Cho’s Global Natural Farming (CGNF)
In a world grappling with food security, climate change, and the rising cost of living, a quiet revolution is taking place on farms across the globe. It’s called Cho’s Global Natural Farming (CGNF), a powerful and simple agricultural system that is empowering farmers to break free from the cycle of expensive chemical inputs and regenerate their land using nature’s own resources.
Developed by a visionary Korean farmer, Cho Han-kyu, CGNF is more than just a farming method—it’s a philosophy centered on simplicity, self-sufficiency, and a deep respect for the living system of the soil.
This article will explore the core principles, practical techniques, global impact, and future of Cho’s Global Natural Farming. We’ll dive into how this unique approach differs from conventional and other organic methods, and how it is proving to be a viable, cost-effective solution for a sustainable future.
With a growing movement of practitioners spanning over 20 countries, CGNF is not just a passing trend; it’s a testament to the power of returning to basics to solve some of our most complex modern challenges.
The Vision and Philosophy of CGNF
Cho’s Global Natural Farming is a complete farming system based on the principles of ultra-low cost, sustainability, and self-sufficiency.
At its heart is a simple idea: that farmers can create all the necessary inputs for their crops and soil right on their own land, using common materials and simple fermentation processes.
This philosophy, often described as “science for the poor,” aims to put the power back in the hands of the farmer by eliminating the need for expensive chemical fertilizers, pesticides, and other inputs.
The founder of this revolutionary method is a Korean farmer named Cho Han-kyu. Motivated by the health and environmental problems caused by chemical-based agriculture, he spent decades developing and refining his techniques.
His mission was to create a farming system that was not only productive but also accessible and affordable for any farmer, anywhere in the world. He envisioned a system that was “farmer-friendly” and “ultra-low-cost,” so that even the most resource-poor farmer could benefit.
This core belief sets CGNF apart from many other farming models, including some organic ones, which can still be prohibitively expensive due to the cost of certified inputs. What truly distinguishes CGNF from conventional and even some other organic farming methods is its approach to input self-sufficiency.
While conventional farming relies on synthetic, often fossil-fuel-based fertilizers and pesticides, and many organic systems rely on commercially produced organic inputs, CGNF champions a “do-it-yourself” approach.
A case study from a Canadian farm reported an incredible 85% reduction in aphid populations and a 45% reduction in overall pest-related crop losses using JADAM inputs, all while improving soil organic matter content by 2.5%.
This success is driven by the farmer’s ability to create their own solutions, drastically cutting down on costs and waste. A farmer in Cebu, Philippines, for instance, reported reducing their farming expenses by a staggering 70% after transitioning to CGNF.
Foundational Principles of Cho’s Global Natural Farming
The success of CGNF is built upon a few core principles that guide every practice and technique. These principles are centered on the idea of working with nature, rather than against it, to create a self-sustaining and resilient farming system.
1. Soil Management
One of the most important principles is a Soil-Centered Approach. In the CGNF philosophy, soil is not just a medium to hold plants; it is a complex and living ecosystem. The primary goal is to rebuild the soil microbiome—the vast community of microorganisms that are essential for plant health and nutrient cycling.
This is achieved by avoiding tillage, which can disrupt soil structure, and by completely eliminating chemical inputs, which can kill beneficial organisms. Instead, farmers use natural inputs to feed the soil and its inhabitants, turning it into a nutrient-rich, living system.
This focus on long-term soil health is a key driver of the method’s sustainability and resilience against environmental stresses.
2. key Natural inputs
Another cornerstone of CGNF is Input Self-Sufficiency. This principle challenges the conventional dependency on a global supply chain for agricultural inputs. Instead, CGNF teaches farmers to use local, readily available materials to create everything they need. This includes things like crop residues, weeds, wild plants, and even everyday kitchen ingredients.
By harnessing the power of fermentation and simple recipes, farmers can produce their own high-quality fertilizers and pesticides. This not only makes farming more affordable but also more resilient to market fluctuations and supply chain disruptions.
3. Crop management
Finally, CGNF promotes a Closed-Loop System, which is a zero-waste, regenerative approach to farming. In this model, everything produced on the farm is either used or recycled back into the system. Crop residues and weeds are not burned but are used for mulching and as ingredients for natural fertilizers.
This continuous recycling of energy and nutrients on the farm minimizes waste and builds a more sustainable and productive agricultural system over time. The result is a farm that not only produces food but also regenerates its own health, becoming more productive with each passing season.
Core CGNF Practices & Techniques
CGNF provides a practical toolkit of techniques and recipes that farmers can use to implement the foundational principles. These methods are designed to be simple, effective, and, most importantly, low-cost.
The heart of the CGNF system lies in its Key Natural Inputs. These are the DIY solutions that replace synthetic fertilizers and pesticides. The most famous of these is the Jadam Microbial Solution (JMS). This is a potent solution rich in indigenous microorganisms (IMOs), which are essential for rebuilding a healthy soil microbiome.
Making JMS is incredibly simple, often involving just a handful of leaf mold (rich in local microbes), a boiled potato (for food), and some sea salt, all fermented in a bucket of water. This single solution can be used to inoculate soil, treat seeds, and boost plant immunity.
Another critical input is Jadam Liquid Fertilizers (JLF). These are nutrient-rich solutions made by fermenting various plant materials, such as weeds, crop residues, or even specific crops like potatoes.
The process is simple: chop up the plants, add water and a source of carbon (like brown sugar), and let it ferment. The resulting liquid is a powerful, low-cost fertilizer that provides plants with all the nutrients they need to thrive.
For pest and disease control, CGNF offers a revolutionary approach with Jadam Sulfur/Pesticides. These are natural, highly effective solutions that replace toxic chemical sprays. A key recipe involves combining sulfur powder, caustic soda, and a natural wetting agent.
This powerful mixture, when applied in the right dilution, can effectively control a wide range of pests and fungal diseases. The use of a Jadam Wetting Agent (JWA), which is also a simple, DIY solution made from oil and a natural emulsifier, ensures that these pesticides and fertilizers stick to the plants’ leaves for maximum effect.
This natural approach not only protects crops but also safeguards the health of farmers and the surrounding environment.
Beyond these inputs, CGNF emphasizes two key Soil Management practices: mulching and no-till farming. Mulching involves covering the soil with a layer of plant material, such as straw or chopped weeds.
This simple act suppresses weeds, retains soil moisture, and adds organic matter back into the soil as it decomposes. No-till farming, as the name suggests, means avoiding plowing or tilling the soil. This practice protects the delicate soil structure and its microbiome, fostering a healthier, more resilient ecosystem.
Global Impact For Cho’s Global Natural Farming
What started as a small movement in South Korea has now become a global phenomenon. CGNF is being adopted by farmers in more than 20 countries, proving its adaptability and effectiveness across diverse climates and cultures.
This rapid expansion is not driven by large corporations or government mandates but by word-of-mouth and the formation of grassroots farmer networks. The benefits of adopting CGNF are compelling and are the primary drivers of its global spread.
The most significant benefit is Cost Reduction. By making their own inputs, farmers can slash their farming costs by as much as 90%. This financial relief is transformative, allowing them to escape debt and reinvest in their communities.
In countries like India, the Philippines, and various parts of Africa and Latin America, where farmers often operate on tight budgets, this economic empowerment is a game-changer. The NITI Aayog report, for example, has highlighted the growing adoption of natural farming in India as a way to boost rural economies.
Another major benefit is Environmental Regeneration. The CGNF method’s focus on soil health has led to significant improvements in biodiversity and ecosystem health on farms. By eschewing chemical pesticides, farmers are seeing a return of beneficial insects and pollinators.
The no-till and mulching practices also help to improve soil structure, increase water retention, and enhance carbon sequestration, making farms more resilient to the effects of climate change.
Implementation Framework and Scaling CGNF
For many farmers, the transition from conventional farming to CGNF can be a multi-year process, but it is a journey of continuous learning and improvement. The first step, Transitioning from Conventional Farming, involves a gradual reduction of chemical inputs while simultaneously introducing CGNF practices, such as creating JMS and JLFs.
Farmers are encouraged to experiment on a small portion of their land first to build confidence and see the results firsthand.
The spread of CGNF is supported by a robust framework of Training Resources. The JADAM organization, founded by Cho Han-kyu, provides extensive educational materials, including a book series titled “JADAM Organic Farming.”
These books serve as detailed manuals, offering step-by-step instructions for all the core inputs and practices. In addition, CGNF is disseminated through workshops, online forums, and farmer-to-farmer networks, which are crucial for sharing knowledge and adapting techniques to specific local conditions.
Despite its rapid growth, CGNF faces certain Scaling Challenges. One major hurdle is the Knowledge Dissemination Barrier. Because the system is so heavily reliant on DIY recipes and hands-on learning, spreading the knowledge effectively can be a challenge, especially in remote areas.
However, this is being overcome by the “open-source” philosophy of JADAM, which encourages practitioners to share their knowledge freely. Another challenge is Adapting to Diverse Agroecological Zones.
What works perfectly in Korea might need slight adjustments in a tropical climate in the Philippines or a dry region in Africa. The local knowledge of farmers is key to adapting the recipes and practices to their specific environment.
Criticisms and Scientific Validation
Like any new or non-conventional farming method, CGNF has faced its share of Common Criticisms. One of the most frequent is the potential for yield variability during the transition period. As the soil ecosystem rebuilds, farmers may experience fluctuating yields.
Another critique, particularly from conventional farmers, is that the methods can seem labor-intensive, especially during the initial stages of preparing the various inputs. Some critics also point to the lack of large-scale, peer-reviewed scientific studies to formally validate the method’s claims.
They question the efficacy of some of the inputs and raise concerns about the potential for pathogens if the fermentation process is not managed correctly.
However, a closer look at the research reveals a more nuanced picture. While there is a lack of large-scale, formal scientific validation from major institutions, there are numerous emerging studies and research gaps being filled by smaller academic and community-driven projects.
Reports from “community service” activities in universities, for instance, have shown that JADAM-based fertilizers have a positive effect on soil health and plant growth.
These smaller studies, while not conclusive, provide a positive body of evidence supporting the method’s claims. They confirm that the natural inputs can indeed restore soil health, improve plant resilience, and even make food safer.
The Future of CGNF
The future of Cho’s Global Natural Farming looks bright and is poised to play an increasingly important role in global food security and sustainability. Its low-cost and regenerative nature makes it a highly relevant solution for addressing the challenges of a growing population and a changing climate.
One of the most exciting developments is the embrace of Innovations. The JADAM organization has developed a mobile app with features like a “Pest Identifier” and a “Mix Master” to help farmers easily create the right concoctions for their needs.
This use of digital tools is helping to overcome the knowledge dissemination barrier and makes the system even more accessible to a new generation of tech-savvy farmers.
Furthermore, there is a growing movement towards Policy Advocacy. In South Korea, the government has already recognized the value of JADAM farming, providing subsidies for ingredients used to make Jadam Sulfur and the wetting agent.
This is a powerful precedent, indicating that CGNF is moving from a grassroots movement to an officially recognized and supported agricultural method. As its benefits become more widely known, CGNF has the potential to be integrated into national agricultural programs, helping to transform food systems on a global scale.
Resources for Practitioners
For those interested in exploring Cho’s Global Natural Farming further, there is a wealth of resources available. The Must-Reads for anyone serious about the method are the books authored by the founder himself, including the “JADAM Organic Farming” series. These books provide comprehensive, easy-to-follow guides for all aspects of the system.
The JADAM organization serves as the central hub for the movement. Their website acts as a digital library, offering articles, videos, and a platform for practitioners to connect and share experiences. Finally, as mentioned, Digital Tools are becoming increasingly important.
The JADAM mobile app and online community forums provide an open-source database of recipes and solutions, making it easier than ever for a new generation of farmers to adopt this transformative approach.
conclusion
Cho’s Global Natural Farming (CGNF) stands as a transformative agricultural approach that empowers farmers to produce healthy, abundant crops while regenerating the environment and reducing costs. Rooted in soil health, self-sufficiency, and closed-loop systems, CGNF offers a practical path away from chemical dependency toward resilient, locally adapted farming.
Its adoption across diverse countries proves its adaptability, while innovations in training, digital tools, and policy advocacy promise to expand its reach. Although challenges such as yield variability and labor demands remain, growing scientific interest and farmer-led success stories suggest CGNF can play a vital role in ensuring food security, restoring ecosystems, and building climate resilience for future generations.
