Freesia is a crop planted from bulbs and is highly vulnerable to severe consecutive planting disorder, making continuous cropping difficult even for 3 years. Despite this, Mr. Go has successfully cropped freesia continuously for 4 years without any major issues. His secret lies entirely in the consistent supply of JMS.

After harvesting the freesia bulbs in mid-May and until replanting them in September, he consistently applied JMS through fertigation once a week without fail. As a result of this thorough application, consecutive planting disorder was kept in check even after 4 years of cultivation. Mr. Go believes that consistent fertigation with JMS before planting not only reduces consecutive planting disorder in freesia but also in leafy greens like lettuce, while also increasing yields and keeping pest and disease pressure in check.

When culturing JMS, Mr. Go adheres strictly to JADAM's philosophy of keeping things simple. He avoids adding compost, urine, or other complex additives, opting instead for a simple recipe containing only leaf mold soil, salt, and potato starch. Even if the culturing process is not complete within 20 hours, he waits patiently for 2 to 3 days. If it absolutely does not progress, he simply adds more leaf mold soil and starch and waits, keeping anxiety at bay.

FAQ: Quick Fact
Q: What is the key secret to avoiding consecutive planting disorder while continuously cultivating freesia for 4 years?
A: The biggest secret was restoring the soil environment by consistently performing fertigation with JMS once a week from the time the bulbs were harvested until replanting.

Mr. Kim became interested in drone pest control after being diagnosed with spinal stenosis. Last year, fearing he might miss the proper timing for pest control in his napa cabbage field due to health issues, he asked a friend who owned a drone to apply it. The results demonstrated exceptionally high efficacy.

For about 0.65 acres of his napa cabbage field, he used JMP and flew a 15 L drone 2 times. He observed that the insects were thoroughly eradicated, lying white on the leaves. Since he achieved the exact same outcome across 3 separate applications, it is no exaggeration to say that JMP drone control delivers outstanding efficacy.

While it is too early to be absolutely certain due to the lack of extensive data on JMP drone control across various farms, Mr. Kim plans to trial JMP drone control on his pepper fields and rice crops this year based on last year's success with napa cabbage. Once the efficacy is further verified, he intends to scale back his tobacco farming and increase his focus on pepper cultivation. By gradually expanding the area under drone control, he aims to compile meaningful data on JMP drone application.

FAQ 
Q: What is the primary reason JMP drone control is drawing so much attention from farmers? 
A: It enables stable pest control with minimal costs and labor, serving as a highly practical alternative for aging farming communities and those facing labor shortages.
 

Seong-hyun Kim of Yeonggwang returned to his hometown 14 years ago to start farming. From his very first year, he challenged himself with Organic Farming but tasted a devastating failure. He planted about 2.45 acres of peppers, but because he only applied compost and did not know how to manage pest control properly, he could only harvest once before plowing the entire field under. Through this, he deeply realized the critical importance of soil preparation and pest control techniques.

Since then, Mr. Kim eagerly attended JADAM lectures and began making donations. Overcoming his disastrous failure, he even obtained organic certification. However, due to the large scale of his farm, direct sales became difficult to manage, and weeding proved too laborious. Today, he has settled into an Ultra-Low-Cost approach, utilizing the JADAM method exclusively for pest control.

Before JMP was invented, he struggled with pepper anthracnose. However, last year, he experienced effective control against anthracnose using JADAM Microbial Pesticide with Sulfur (JMP.S), which is JMP with sulfur added. Encouraged by this, he expanded his pepper cultivation area this year.

Although he gave up organic farming due to weeding challenges, JMP is sufficient for pest management. Consequently, no synthetic pesticides are used at all, as he relies solely on JMP and JMP.S for control. He makes a 1-year supply of JMP all at once in the spring when he has more free time.

When culturing JMS, Mr. Kim installs a heater rod at the bottom of the container instead of using a coil immersion heater, and cultures it by leaving the leftover microbial sediment without cleaning the container. By setting the temperature of 500 L of groundwater to 30°C and adding 500 g of leaf mold soil, 500 g of salt, and 500 g of potato starch, the culture succeeds without a single failure, even without increasing the amount of leaf mold soil or potato starch, or adding other compost or urine.

FAQ: Quick Fact 
Q: What was the decisive turning point that allowed a farmer who suffered an initial failure in organic farming to successfully stabilize pepper cultivation? 
A: After realizing the importance of soil management and pest control techniques, Mr. Kim consistently put JADAM lectures into practice. In particular, he successfully controlled anthracnose using JMP and JMP.S, which enabled him to expand his cultivation area.

Because Mr. Kim had experience culturing microorganisms from the past, making JMP did not pose any major difficulties. In the early days, right after he sprayed JMP, cabbage white butterfly caterpillars that got hit by the spray dropped right off, making him marvel at its high efficacy. However, when he checked back a short while later, those caterpillars had disappeared somewhere. When he asked Dr. Youngsang Cho about it, Dr. Cho explained that this can happen if the JADAM Microorganism Solution (JMS) is not cultured properly. Since then, he has paid much closer attention to culturing JMS.

Other farmers said it takes 20 to 24 hours, so to speed up the process, he tried adding some molasses, more leaf mold soil, and even Heuksari compost. However, even after 20 hours, rich bubbles did not form. Since he only needs to spray once a week, there was no need to be constrained by time. He left it alone and kept watching, and after 36 hours, the bubbles were boiling over. He concluded that it is best to culture without being obsessed with time, adapting the process to one's own pest control schedule.

Because coil immersion heaters break down or burn out once or twice a year without fail, he custom-built and used a separate temperature controller. This keeps the temperature consistently regulated and eliminates fire hazards. He continuously uses the leaf mold soil pouch until it becomes too heavy with accumulated sediment to lift; only when it gets that heavy does he discard the contents and refill it. He does not clean the JMS culture container either, simply filling it back up with water over the leftover microbial sediment to reuse it. Culturing this way still yields a highly active microbial solution where the bubbles do not easily break once they form.

FAQ: Quick Fact 
Q: Is it absolutely necessary to limit the JADAM Microbial Pesticide (JMP) culturing time to 20–24 hours? 
A: On-field experience shows that visually checking the bubble status and microbial activity is far more critical than sticking to a set timeframe; allowing ample time according to the farm's schedule yields a much more stable control effect.
 

Before JMP was invented, Mr. Kim unconditionally made and used the JADAM No. 12 Comprehensive Germicide and Pesticide (per 500 L: 1.2 L of JS, 10 L of JADAM Wetting Agent (JWA), and 15 L of JADAM Herbal Solution (JHS) made with ginkgo nuts). However, since planting his strawberry seedlings last September, he has been making and using JMP. After trying JMP, he found that spider mites were completely eradicated and no longer visible. It also controls aphids well, but some pale aphids remain on the undersides of the leaves. He believes the issue is that the spray did not thoroughly coat the undersides of the lower leaves near the ground while using the high-pressure sprayer. When controlling pests, it is crucial to spray thoroughly so that the solution coats the plants completely.

Looking at Mr. Kim's cultivation schedule, once the strawberry harvest ends in May, he floods the greenhouse, closes all the doors, and performs solarization. From July, he conducts fertigation with JADAM Microorganism Solution (JMS) about 4 times on the strawberry ridges before planting the strawberry seedlings in September. Prior to planting, he applies about 30 bags of Heuksari compost per 150 pyeong (≈ 0.12 acres). Once the strawberries begin to bloom, he dissolves compound fertilizer in water and injects it during fertigation.

After planting in September, he sprays 350 L of JMP once a week unconditionally without a second thought. Starting the pest control at dawn on Saturdays, when there are no strawberry deliveries, takes about 2 and a half hours. He has purchased several types of Yamaho nozzles and alternates between them to compare which one provides a finer mist and wider coverage. He uses only JMP from September to January, and switches to making and using JMPS by mixing in JS when mold begins to appear in January.

FAQ: Quick Fact 
Q: What is the core secret behind Mr. Hyung-tae Kim's ability to increase pest control efficiency for his strawberries using only JMP? 
A: Instead of frequently changing chemical products, the core to achieving stable control is spraying consistently once a week and repeatedly adjusting nozzles and spraying methods to ensure the solution thoroughly coats the undersides of the leaves.
 

Even though he has already made 2 tons of JMP, he is currently culturing JMS to make more JMP. Making a large batch in the spring allows him to conveniently use it whenever needed, and it feels like using it for free, eliminating any financial burden.

Because Mr. Lee attended JADAM lectures in the past and had experience culturing JMS, he has never failed in culturing JMS when making JMP. He draws groundwater and lets it sit for 2 to 3 days. Then, he heats it with a coil heater and adds plenty of leaf mold soil, over 700 g, to 500 L of water. Since he grows potatoes, he boils potatoes instead of using starch, adding a generous amount of 2.5 to 3 kg. When plenty of leaf mold soil and boiled potatoes are added this way, culturing JMS is completed in just 17 hours. Finding it a hassle to weigh the salt every time, he puts 10 kg of salt in a 45 L container to make saltwater, and scoops out 2 L with a beaker each time to add to the mixture.

When culturing JMS is finished, he does not wash the container. Leaving the leftover microbial sediment and culturing it again yields excellent results. In the greenhouse, he uses only JMP. In the open field, he mixes it with JS to make JMP.S during the rainy season. He applies control measures every 5 days when pests and diseases are visible, and unconditionally once a week during normal times. When growing cabbages, he sprays JMP even if bugs are not visible. When he checks the next morning, the bugs have come out and died.

FAQ: Quick Fact 
Q: What is the reason for continuing to culture even after securing 2 tons of JMP, and what benefits does this provide to real farms? 
A: By making a large amount in advance, it can be used immediately whenever needed without cost burden, drastically reducing pesticide costs and improving work efficiency.
 

Before planting peppers in the greenhouse, Mr. Lee applies JMS fertigation 4 times. In addition to JMS, he fertigates with fish JLF and wood vinegar, following a weekly rotation of JMS, fish JLF, JMS, and then wood vinegar. Fish JLF is used to supplement nitrogen, while wood vinegar—harvested from a wood-burning boiler and aged for about 1 year—is applied to provide an effective defense against anthracnose and wilt disease.

After the pepper harvest ends in late September, the residues are left on the ground. Around late October, barley seeds are scattered by hand, followed by a light tilling. After tilling, he simply sprays water once using a sprinkler, and the barley sprouts well and grows without much intervention. In early March, when the barley reaches knee height, he tills it into the soil and adds 40 to 50 bags of organic certified ‘Tokok’ compost to his 0.12-acre greenhouse before tilling again. He relies on the green manure and compost for basal fertilization and does not apply any separate top-dressing, instead meeting the plants' needs through regular fertigation with JMS, fish JLF, and wood vinegar.

The row spacing for the peppers is 1.7m, with 50 to 60cm between plants, allowing for 530 plants in the 0.12-acre greenhouse. Mr. Lee finds pepper farming rewarding as he achieves a yield of 0.6kg (1.3 lbs) per plant—a target many pepper farmers dream of—resulting in a total of 300kg (660 lbs) from his greenhouse.

FAQ: Quick Fact
Q: How did the sequential fertigation of JMS, fish JLF, and wood vinegar lead to such high yields and cost savings?
A: By maintaining soil stability without separate top-dressing, he achieved a harvest of approximately 300kg (660 lbs) in a 0.12-acre greenhouse, significantly reducing costs for fertilizer and pesticides.
 

Mr. Lee, a resident of Suncheon, returned to his hometown to take over his parents' farm 18 years ago. Committed to practicing organic farming from the very beginning, he has attended JADAM Lectures 6 times in various locations including Hadong, Daejeon, and Gongju.

His first year in agriculture was a devastating failure. After just one harvest, his peppers were ploughed under due to anthracnose, and his cabbage crops suffered the same fate because of clubroot before he could even harvest them once. While he briefly considered giving up on KNF, he regained his resolve. By mastering the use of JWA, JS, and making JADAM Herbal Solution (JHS) with ginkgo nuts, Korean pasque flower, and Jerusalem artichoke, he refined his technical skills and successfully obtained organic certification.

Since JMP was invented last year, he says farming has never been easier. Because he can produce it in bulk and use it as if it were free, the burden of management has vanished. Having practiced making JMS for 15 years, he achieved vigorous microbial activity without any issues, never once failing a cultivation. The entire yield from his 1.63-acre farm is sold at Suncheon Local Food markets. His venture is highly successful, as his products sell out despite being priced significantly higher than conventional produce.

FAQ:
Q: How did JMP and self-culturing technology allow farms to simultaneously achieve cost reduction and production stability? 
A: By making large quantities at once for repeated use, pesticide costs were virtually eliminated. Additionally, stable JMS cultivation ensured high productivity by providing a robust defense against diseases.
 

They used to live in Gyeonggi-do, but through connections with Mrs. Lee's acquaintances, they moved to Hongcheon, Gangwon-do to farm. When they previously had a small vegetable garden, they hated the smell of pesticides so much that they decided to do organic farming if they ever became farmers. While looking for various eco-friendly farming methods, they were impressed by Dr. Youngsang Cho's YouTube videos on no-till farming, so they attended JADAM Lectures together.

However, they were still unsure if it was right for them, so they initially farmed using commercial eco-friendly materials. As the weather got hotter, many diseases occurred, but the commercial eco-friendly materials were only expensive and ineffective. This led them to recall the JADAM Organic Farming materials they had learned before. They made and used JADAM Sulfur (JS) and JADAM Wetting Agent (JWA). Since JMP was invented, they have mainly been using JMP for their farming.

Since they could not apply JADAM pest control throughout the entire growing season last year, they plan to properly practice it starting from the seedling stage this year.

Frequently Asked Questions
Question: Why did Mr. and Mrs. Yoo switch to JADAM Organic Farming instead of using commercial eco-friendly materials?
Answer: Commercial eco-friendly materials were expensive and ineffective against the increasing diseases caused by climate change. By switching to JADAM Organic Farming and making their own materials like JADAM Microbial Pesticide (JMP), JADAM Sulfur (JS), and JADAM Wetting Agent (JWA), they were able to significantly reduce pesticide costs and take control of their pest management.
 

When they first tried culturing JMS, they started around evening. It was not ready even after 48 hours, so they dumped it all out and started over. During the second attempt, they added 500g of sea salt to 500L of water. They doubled the amount of leaf mold soil and potato starch to 1kg each. They heated it, and the culture was finished in 30 hours.

Someone mentioned leftover microbial sediment. So for the third attempt, they did not clean the container used for the second batch. They added another 500g of sea salt, 1kg of leaf mold soil, and 1kg of potato starch to the leftover microbial sediment. The time was significantly shortened, and the culture was finished in just 11 hours.

Some might suspect that it was not fully cultured. They might think the foam from the leftover microbial sediment caused an optical illusion. However, the initial foam almost disappeared while the water was heating up. After 8 hours of culturing, foam started to form around the coil heater. Seeing the entire container fill with foam in 11 hours confirmed that it was properly cultured.

They were able to reduce the culturing time by repeating this up to four times without cleaning the container, simply doubling the amount of leaf mold soil and potato starch. Adding Heuksali compost (organic compost) and molasses also helps to cut down the culturing time.

Question: How can the culturing JADAM Microorganism Solution (JMS) time be reduced to 11 hours?

Answer: You can drastically reduce the culturing time by continuously utilizing the leftover microbial sediment without washing the container. Along with this, double the amount of leaf mold soil and potato starch from 500g to 1kg while heating the water. Adding a small amount of Heuksali compost or molasses can also help speed up the culturing rate.

Mr. Choi makes two tanks of JMS once a week, doing so outdoors even in the middle of winter. He fills two 500L tanks with water and first heats the water to 35 degrees using an immersion heater. To this, he adds 500g of leaf mold soil, 500g  of salt, and 500g of boiled potato starch. He cultures both thanks simultaneously. In a recent instance, after 22 hours, one tank was foaming vigorously and was almost finished, while the other tank was just starting to foam showing a stark contrast in culturing speed. Why is there such a difference in culturing speed under the exact same conditions?

For one tank, Mr. Choi cultured JMS by leaving the leaf mold soil residue from the previous batch in the mesh bag and simply adding more leaf mold soil residue from the previous batch in the mesh bag and simply adding more leaf mold soil, resulting in a much faster and richer culture. He has repeated this process of adding leaf mold soil without washing the bag up to 5 consecutive times, and it consistently cultures richly without any issues. 

For the other thank, Mr. Choi cleaned it thoroughly and added a small amount of leftover microbial sediment, but the temperature and time being identical, the culturing speed was noticeably delayed. This practical observation provides valuable insight into the microbial culturing process.

Q: What causes the difference in JMS culturing speed under the same conditions? 

A: Maintaining the continuity of microorganisms by reusing the leaf mold soil mesh bag without washing it results in a much faster and more vigorous culturing process compared to starting with a thoroughly cleaned tank.

When he first attempted no-till farming last year, he wondered if it would really work, but the farming was successful without any issues. Preparing for no-till farming again this year, he left the chili pepper residues in the furrows as they were in February and applied 12 bags of organic compost to the ≈ 0.12 acre greenhouse. After making the ridges by turning the soil in the furrows once with a cultivator, he drenched the soil thoroughly with JMS twice. He plans to drench it about two more times before planting the chili peppers in mid-April, which means a total of four JMS drenches will be applied before planting.

He cultures JMS regularly once a week. When drenching JMS, adding a small amount of liquid fertilizer, such as fish liquid fertilizer or bone meal liquid fertilizer, at about 300 mL per 500 L ensures there is no lack of nutrients. He makes JMP once a month. Preparing one 500 L batch lasts for a month, which costs no money and simplifies the farming work, allowing him to farm with physical and mental ease.

After planting chili peppers or onions, he begins pest control once every 5 days. Initially applying it every 5 days and later just once a week, controlling pests with JMP alone ensures successful farming without worrying about diseases or insects. He uses JMP as the base for pesticides. Only occasionally during mid-summer when pest pressures are high, he applies JMP.S, which is made by adding JADAM Sulfur (JS) to JMP. This approach effectively keeps pests in check, making farming simple and easy.

The case of farmer Gyeong-seop Choi, who connects small-scale multi-crop production with local food direct markets, presents a sustainable model that modern eco-friendly organic farming should pursue. Starting from the philosophy of Korean Natural Farming (KNF) introduced by Master Han-gyu Cho, this method applies the Ultra-Low-Cost farming system of JADAM Organic Farming to the field, achieving the dual goals of reducing production costs and restoring the ecosystem. In particular, it is highly notable that the problem of pests like aphids, which is considered the greatest difficulty in early farming, was resolved through no-till farming and formulating self-made JADAM  Microbial Pesticide (JMP).

Gyeong-seop Choi, who runs Chamsaegol Green Farm (Sparrow Valley Green Farm) in Sejong, says he thought he should do eco-friendly farming someday while taking KNF lectures from Master Cho when he was working. While working in Busan, he started farming in a kitchen garden, and after retiring, he took JADAM lectures in Hadong and settled in Sejong to start farming about 2.45 acres with small-scale production of multiple varieties. Although it is a lot of work due to the diverse crops, it is rewarding because he sells to 4 local food stores and a Nonghyup Hanaro Mart (a Korean agricultural cooperative market) in Sejong, so there is no worry about sales.

From the beginning of his farming, he farmed in an eco-friendly way as he learned from JADAM and received organic agricultural product certification. Even though he prices his products 10 to 50 percent higher than regular agricultural products at the local food store, many people recognize the value and buy them, so they sell well. Small-scale multi-crop production requires a lot of labor, from small packaging to local food displays, but since his wife dislikes farming, he finds it comfortable to work alone without forcing her to come to the field. He starts working at 6 in the morning and works until 8 or 10 at night, but he doesn't consider it work. He lives joyfully without feeling tired, thinking of it as playing and communicating with the crops.

In the early days, controlling aphids was somewhat difficult, and there were tough times when he had to apply treatments continuously every 1 or 2 days. However, now with no-till farming and making JMP, pests are successfully controlled just by applying it once a week, so there is no difficulty.

Sa-kyun Kim continuously cultures JADAM Microorganism Solution (JMS) to control pests on his chrysanthemum farm of about 2.5 acres. He initially used a standard immersion heater ("pig tail") to adjust the temperature, but it broke down frequently. After removing the heater's internal sensor and installing a separate temperature controller, there have been no breakdowns, and he has completely eliminated the stress of maintaining the temperature.

At first, moving the microbes from the culturing tank to the pesticide tank was extremely difficult. He built a unified system that connects the JMS tank directly to the pesticide tank, the fogging system, and the soil drenching tank. He is now using it with great ease. It is convenient to store all the tools needed for making JMS on a cart and push it around for use.

When making JMS, he adds 500g of leaf mold soil, 500g of salt, and 500g of starch to 500L of water. He also adds 200g (about 2 handfuls) of "Heuksal-i" compost. Using a microbial starter (leaving a small amount of previous JMS) enables more vigorous culturing.

Foam that is resilient and restores itself even when touched by hand. For vigorous microbial culture, adding "Heuksal-i" compost and about 50L of microbial starter to the basic conditions produces JMS with large, viscous foam within 20 hours.

 Jinyoung Park, who returned to farming in Jeju Island in 2016 started tangerine farming in 2018. He decided to farm with eco-friendly methods from the start and studied by watching JADAM lectures on YouTube more than 50 times. Thanks to that, he was able to perfectly control Ruby scale insects, which are considered one of the most difficult pests in tangerine farming.

Ruby scales, which cause significant damage to Jeju tangerine trees, are such troublesome pests that even pesticide companies say they cannot control the adults. However, after successfully controlling Ruby scales this year with JADAM Microbial Pesticide (JMP), it feels like a new world of agriculture has opened up.

On the surface, it looks like Ruby scales are still stuck to the tangerines trees. However, if you press live Ruby scale, red body fluid comes out, whereas dead ones have turned into jelly gum or have fungus on their carcasses. On Mr. Jinyoung Park’s tangerine trees, not a single live scale insect could be found; they were all exterminated. It is said that there is nothing difficult in tangerine farming if you can just control citrus leafminers and Ruby scales. Now that he can successfully control Ruby scale insects, he is confident that a major change will occur in Jeju Island tangerine farming.

When making JADAM Microorganism Solution (JMS) initially, he went to an Oreum (volcanic cone) to leaf mold soil, but now there is no problem collecting it from around the tangerine field. He uses potato starch and utilizes seawater, taking advantage of the characteristics of the Jeju region, to culture JMS. At first, he suffered a lot because making JMS did not go well due to abnormal low temperatures, but after succeeding once, culturing continues to go well now. You should set the temperature to 32 degrees with a pig tail heater and not be bound by the “20-hour culturing” rule. Just culture JMS until bubbles become vigorous, whether it takes 2 days to 3 days.

Mr. Jong-ryul Lee, who cultivates rice on about 24.5 acres in Damyang, Jeonnam, encountered JADAM by chance. Realizing, “This is the true alternative for eco-friendly agriculture,” he immediately took the lectures and began donating to JADAM.

He was actively practicing JADAM Natural Pesticide (JNP) by making JADAM Sulfur (JS) and JADAM Wetting Agent (JWA) and boiling ginkgo nuts (JHS). Upon hearing the news that JADAM Microbial Pesticide (JMP) was invented, he immediately started manufacturing it. Initially, when making the JMP, he cultured JADAM Microorganism Solution (JMS) by grinding boiled potatoes. However, after hearing that starch was more effective, he switched to using starch, but he faced continuous failures in culturing thereafter.

After failing more than 10 times, he inquired with Dr. Youngsang Cho and found that storing starch in a low-temperature warehouse was the problem. He bought new starch and tried culturing again, but the failures continued. Upon consulting with Dr. Cho again, he discovered the cause was not boiling the starch sufficiently. Since undercooked starch cannot serve as food (medium) for microorganisms, he changed his method from roughly boiling the starch to boiling it thoroughly until bubbles rose vigorously. Finally, the culturing JMS was successful. 

First, never store starch in a low-temperature warehouse; keep it at room temperature. Second, when boiling starch, it is fine to boil it for a longer time, so boil it thoroughly until bubbles rise sufficiently. If you are careful about these two points, making JMS will proceed smoothly without significant difficulties.

Changseol Lee named his farm Tree Frog Farm because the area was filled with green tree frogs, which became the farm’s symbol. The frogs were always jumping around the beds, a sign of a healthy ecosystem. However, during a winter crop season, severe aphid infestations forced him to use several organic commercial inputs. The result was shocking: the frogs vanished, and Lee realized something was deeply wrong. “This isn’t right,” he thought. That awareness changed everything. Searching online, Lee came across JADAM Microbial Pesticide (JMP) and decided to try it. Since then, he hasn’t had to worry about pests.

Because his greenhouse stands beside a rice paddy, the humidity is high and slugs used to thrive. At night, they were so dense it looked as if white flowers had bloomed across the lettuce beds. The damage was severe, he often had to abandon one-third to two-thirds of his crop. Then he began spraying JMP 3 times a week in the evenings. Astonishingly, the slug disappeared. Even grasshoppers, which once swarmed the fields, have all but vanished. Now Lee says he doesn’t worry about pests at all. 

As long as you follow what JADAM teaches, there is no problem, he says. After 2 to 3 successful JADAM Microorganism Solution (JMS), anyone can handle it. Compared with the organic commercial pesticides he once bought, costing nearly $296 per month, his costs dropped dramatically. Making JMP is simple: collect water, mix in leaf mold soil, culture the microbes, add decyl glucoside, and spray. Repeat the process, and success naturally follows. For Lee, Tree Frog Farm now thrives again, tree frogs hopping, lettuce lush and green, and no need for chemical pesticides.

In conventional organic farming, crop rotation is emphasized to prevent diseases, but JADAM thinks differently. In the JADAM method, continuous cropping, growing the same crop repeatedly, is believed to achieve higher yields more quickly. Thirty years of farming experiences have proven this to be true.

Continuous cropping disorder refers to the phenomenon in which the nutrients required by a crop become depleted as the same crop is cultivated repeatedly in the same soil, making cultivation increasingly difficult. Therefore, most farmers have been taught to practice crop rotation and believe it is the only path to abundant harvests. However, JADAM began to question whether continuous cropping necessarily leads to crop failure and sought answers from nature. 

In nature, there is no such thing as “crop rotation". The same species can grow in one place for decades, even centuries, without any problem. The trees in the forest do not wither with time. Instead, they become even more lush. This is because nature does not view stems and leaves as sources of disease but as nutrients to sustain life. In autumn, fallen leaves and branches return to the soil, becoming nutrients for the trees once again. This is nature’s continuous cropping, the most perfect form of farming.
The difference between human farming and nature’s farming is that humans remove stems and leaves from the field, thinking they are breeding grounds for disease and pests, while nature recycles them as the best source of nutrients. The stems and leaves contain precisely the nutrients that the crop needs. When they return to the soil and decompose, they become fertilizer with the ideal nutritional balance for that crop.

JADAM sees crop residues not as a source of disease, but as a rich source of nutrients. Therefore, JADAM strongly recommends making compost or liquid fertilizer from crop residues and returning them to the soil. Through this process, the soil becomes more nutrient-rich each year, eliminating continuous cropping problems and allowing for truly abundant harvests. 

Many agricultural experts claim that crop residues must be removed to prevent diseases such as anthracnose or powdery mildew in the following season. However, these pathogens already exist naturally in the soil as part of the microbial ecosystem. Removing crop residues does not eliminate them. Just as humans cannot completely separate themselves from the common cold virus, the key is not to eradicate microbes but to maintain a healthy ecological balance. 

JADAM researches and promotes organic farming techniques, but it does not support crop rotation. Agricultural technology should follow nature. Nature does not discard diseased leaves, it transforms them back into nutrients. By following this same cycle, human farming can also achieve perfect ecological balance and the path to high yields. 
 

The beet armyworm (Spodoptera exigua) is a pest widely distributed across the world, inhabiting temperate and subtropical regions. It particularly prefers warm and dry climates and causes severe damage in Asia, including Korea, as well as in North America. With the expansion of international trade and logistics, infestations are increasingly being reported in new climate zones.

The beet armyworm is a highly polyphagous pest, attacking over 200 different crops. Major hosts include vegetables, beans, ornamentals, and cotton, where it causes significant damage. Depending on the temperature and region, it can produce 5–7 or more generations per year. After hatching, larvae actively feed on crops for 2–3 weeks before pupating and then emerging as adults to repeat the cycle. The larval stage is the most destructive: early instar larvae (1st–2nd instars) feed in groups on the undersides of leaves, scraping away the tissue and leaving only the epidermis, resulting in whitish damage (leaf “skeletonization”). As larvae grow (3rd instar and beyond), they consume entire leaves or bore into fruits and stems, causing much more serious injury. If not controlled at this stage, crop growth is severely hindered, and yields drop drastically.

The beet armyworm is notorious for developing resistance to chemical pesticides. Repeated use of the same pesticide quickly becomes ineffective, and cross-resistance to new chemicals often develops as well. Its rapid reproduction and high fecundity mean that missing the control window leads to explosive population increases. Since adults are nocturnal while larvae hide during the day on leaf undersides or inside plant tissues, pesticides often fail to reach them effectively. With its wide range of host crops, infestations also spread rapidly.

Multinational pesticide companies are racing to develop microbial pesticides against this pest, but most of these products remain expensive, narrow in spectrum, and only partially effective. By contrast, the JADAM Microbial Pesticide (JMP), invented by Dr. Youngsang Cho, offers a groundbreaking alternative that overcomes all of these shortcomings.

This video demonstrates the control of beet armyworm with JMP—one of the most difficult pests to manage. JMP can be easily self-manufactured by farmers using inexpensive materials, yet it delivers powerful, broad-spectrum pest control. It empowers farmers to take pest management into their own hands while opening a new path forward for organic farming worldwide.

 The ten-spotted ladybird beetle (Henosepilachna decempunctata) is an insect belonging to the order Coleoptera and the family Coccinellidae. Its body length is around 1 cm, with a light yellowish-brown color marked by 10 distinct black spots, making it look very similar to beneficial ladybird beetles. It is widely distributed across Asia, including Korea, Japan, China, India, and Southeast Asia.

This beetle causes significant damage to crops, particularly those in the Solanaceae family. Both adults and larvae feed on the epidermis and mesophyll of leaves, leaving only the veins and creating a net-like appearance. Severe damage disrupts photosynthesis, stunts plant growth, and reduces yields. The beetle is active mainly from May to September, with peak damage occurring in June and July when larvae are abundant. Depending on the climate, it has 3–4 generations per year. Overwintered adults attack crops in spring and lay eggs, which hatch in 1–2 weeks. The larvae then cause major damage before pupating and emerging as adults, repeating the cycle throughout the growing season. Populations increase rapidly during the summer months.

Most ladybird beetles are well-known as beneficial insects that prey on aphids, but the ten-spotted ladybird beetle is often mistaken for such beneficial species due to its similar appearance. Unlike predatory ladybirds, this species is plant-feeding, making it a pest rather than a natural enemy of aphids. Some related phytophagous ladybirds have even been reported to bore into and feed on eggplant fruits, creating further confusion for farmers. While the commonly beneficial ladybird has seven spots, this pest species is marked with ten spots, and its relative, the large 28-spotted ladybird beetle (Henosepilachna vigintioctomaculata), has 28 spots and also damages crops.

Unlike many insect pests that damage crops only at specific stages, both adults and larvae of the ten-spotted ladybird beetle feed on plants throughout the growing season, making damage prolonged and severe. Its wide range of host plants also makes it difficult to control. With multiple generations per year and high reproductive capacity -each female lays hundreds of eggs - the population grows quickly. Adults are capable of flight, allowing them to migrate easily between fields. Chemical pesticides can achieve partial control, but larvae often hide on the undersides of leaves where sprays cannot reach, and adults can escape and reinfest crops. Furthermore, the beetle quickly develops resistance, reducing the effectiveness of repeated pesticide use.

At JADAM Organic Farm, the application of JADAM Microbial Pesticide (JMP) to larvae feeding on grape leaves demonstrated strong control effects, as shown in the latter part of the video. JMP is highly effective against a broad range of pests and has the major advantage of not inducing resistance. Over two years of field testing on nearly all insect pests found on the farm, JMP was effective against almost all species. One of the most remarkable outcomes is its ability to completely eliminate mosquitoes.
