As we go deeper down the rabbit hole this grow season. I will continue to discuss concepts and ideas to consider that will help you as a grower this year. But this week I want to interject with an important nutrient conversation. One that is one of my personal favourite growing methodologies as an organic grower. If you haven’t heard of it or want to give it a go. Have a dive into this week’s topic, Korean Natural Farming.

Korean Natural Farming uses methods that observe the laws of nature and utilize natural materials and products. It is based on the principle of interdependence among all living things. It aims to have a nurturing impact on the environment, in sharp contrast to the disadvantageous effects that often accompany modernized and commercialized agriculture. The observance of the natural cycle and environment-friendly agricultural practices applied in a modern setting refreshes the established perspectives on farming and provides an alternative to technology-intensive agriculture.

How Korean Natural Farming Began

Korean Natural Farming (KNF) was developed by Dr. Cho Han Kyu at the Janong Natural Farming Institute in South Korea. It was originally intended to change the chemical-based and harmful farming methods that were being practised in South Korea. Together with like-minded farmers, he converted his lifelong studies and his own experiences into an innovative farming system that not only promotes respect and care for the environment but also produces more with less cost and labour. KNF Farming recognises the abundance of nature and utilizes indigenous resources for production. Its basic philosophy is to maximize the inborn potential of a life form and its harmony with the environment by not interfering with its growth and development or forcing the crops to yield more than what they can. KNF Farmers believe that the best way to achieve top-quality yield is to respect the nature of life.

The Methodology

The KNF methodology is based on the Nutritive Cycle Theory, which guides the KNF Farmer on what inputs to apply, how much and how often. Korean Natural Farming applies the principle of interdependence in which people should nurture, instead of surmounting it or undermining it. KNF Farming is also envisioned so as to contribute to the alleviation of poverty, disease and environmental destruction by providing an alternative means of livelihood and food production.

As a farming method that goes back to basics using materials from nature and without force or chemicals. KNF Farming guarantees its farmers healthy and strong products needed to provide for their families and society. KNF respecting the natural cycle of life is more than a farming technique. It is a philosophy, a new economics and a way of life.

Strengths and Benefits

Environment-Friendly: Its inputs are made from natural materials, protecting the crops from harmful chemicals used as fertilisers in modern agriculture. In livestock raising, Natural Farming is considered a revolutionary breakthrough, accomplishing the dream method of “Zero emission”. No wastewater is emitted. Also, wastes are recycled and converted to resources.

HigherYield: It strictly follows the Nutritive Cycle Theory, using accurate amounts of substances at the precise moment, nourishing the soil with the right amounts of nutrients when the plants need it. Hence why we discussed in our previous blogs how important it is to test your soil. Here is a link to Kaya Farms, they are local and have an amazing team.

Low Cost: It helps lessen the farmers’ financial burden with the use of homemade materials and making use of resources from the farm. Often recipes call for leftovers like rice or kitchen scraps. Making it ideal for those looking to produce something from nothing too.

High Quality: Better-quality crops and livestock is the result of the non-usage of chemicals that are harmful to their production as well as the environment. This has been proven many times since 2011. From increased terpenes to more natural expressive flowers. KNF inputs are superior when done in sync.

Adaptable: KNF can be replicated in any region of ingredients and products used. All areas are unique and this allows for a more eco-friendly nutrient cycle for the plants. Ingredients can be substituted as long as the core ingredients are being respected.

User Friendly: Methods are free of toxic and poisonous chemicals, which are dangerous to a user’s health. With Natural Farming, farmers cultivate their own substances that truly provide the nutrients to the crops and animals, it also helps without harming the plants, animals and humans.

Respect for Life: Natural Farming gives utmost respect and care to the crops and animals following the natural cycle of life. Better productivity and even better harvest can be made when one nurses and gives attention to the environment.

The Nutritive Cycle Theory

The Nutritive Cycle Theory states that plants and livestock need different nutrients during different stages of growth. Like humans, plants also need different kinds of food at different stages. Just as a baby can only eat baby food, young plants or animals can only be fed with nutrients that are appropriate for their age. The Nutritive Cycle guides farmers in obtaining the best results from their crops and avoiding disease to their crops through proper nutrient management. The Growth and development of a plant takes a certain course along with the passage of time. All crops go through the stages of growth according to the qualitative changes that occur and mature with flowering and fruiting.

Importance of IMO

KNF produces a good yield when the land cultivated has an excellent soil condition for crops. Microorganisms play an important role in making soil good for growing plants. These microorganisms can also be collected and cultured. Natural Farming promotes the use of Indigenous Microorganisms (IMOs).

The microorganisms that have been living in the local area for a long time are best for farming because they are very powerful and effective. They have survived and can survive the extreme climatic conditions of the local environment much better than artificially produced microorganisms, which are cultured in some foreign or artificial environment. And since they are already available in the field, they are considered the best inputs for conditioning the land.

Organisms that are found under the heat of the sun are largely different than those found in shaded areas such as under bamboo trees. Dr. Cho and Dr. Elaine Ingham from the Soil Food Web advocate that it is better to culture microorganisms from different areas in order to collect different kinds of microorganisms (Microbial Diversity).

Korean Natural Farming Inputs

It is also good to culture microorganisms at different weather conditions and to mix different types of microorganisms. In “Non-Chemical” agriculture practices we do not feed the plant. We nurture the soil and the soil nurtures the plant through the IMOs. Microorganisms have two major functions in farming:

Microorganisms decompose complex organic compounds such as dead bodies of plants and animals and wastes into nutrients, making them easily absorbable by plants.

They can create compounds such as antibiotic substances, enzymes and lactic acids that can suppress various diseases and promote healthy soil conditions.

Here is how I go about making IMO

It is best to use leftover rice. This will ensure that the rice is not soft or sticky. Rice is placed in a ‘wooden box’ with small holes in the bottom – I normally use a cardboard box. You want to avoid using plastic or glass.

The box is covered with a paper towel. And that is your basic set-up.

Now all that needs to be done is, you have to take your box to an identified fugi dominant area. Usual forestry, old growth woods areas are ideal. A place in which decomposing of plant material is happening naturally, where leaves fall from the trees. You want to look for the best place in the shade and place the box in between the organic matter.

A small collection of sticks and leaves with mycelium attached are laid gently over top of the paper towel—a handful will do.

This rice box is then covered with a tarp and left for 3 to 7 days depending on the temperature (less time in warmer periods), or until mycelium and other microbial populations have colonized the rice in the form of white hyphae spreading through it. The rice should look like a fungus cake almost.

This is what KNF practitioners call IMO-1 (the first stage of IMO). The rice and “mold” is then weighed and mixed together with brown sugar. This sugar stabilizes the microbes, essentially sending them into an arrested state (called IMO-2) where they can easily be woken back up again. Then it is mixed with rice bran or some other carbonaceous material in low piles and lightly composted to enliven the indigenous microorganisms (which makes IMO-3). That mixture is then added to soil and composted at low temperatures again (IMO-4), which itself can be diluted and sprayed on fields or added to a compost pile or woodchips to be composted a third time (making the final IMO-5).

All of these preparations have multiple uses, and KNF deals with more than just soil. There is a whole side to the practice that deals directly with the plants. As stated above, adding the right nutrient at the right time is a critical part of KNF. For instance, Cho recommends a water-soluble calcium (abbreviated WS-CA, made from toasted egg shells and vinegar) at several different stages including “the cross-over period when the growth of crop changes from vegetative to reproductive growth.” Most of the preparations have a multitude of applications and are shelf-stable for months if not years of utility. So even if a little money is needed for brown sugar or rice, that investment theoretically pays back for many years to come.

How to utilize IMO

In order to be effective, use IMOs continuously. Since IMOs are used to make soil fertile and healthy, these should be collected and prepared as the season progresses each year. In order to bring about continued results. IMOs must be maintained in the soil. Avoid being choosy in collecting microorganisms. Instead, microorganisms from different environments should be collected and mixed. It is recommended to collect IMOs from all four directions of the field. We can also collect microbes from mountains, summits, valleys and trenches.

Personally, I prepare IMO and store it as IMO-2 only before and in the middle of my growth cycles do I then apply it. So I only really make as much as I need for the amount of plants I am growing. Whatever is left is added into the compost teas later on in the cycle. So during the transition period of the plants I culture different IMOs again.

After farming KNF it is hard to change direction back. This has been my findings. There is so much more to be said on IMO alone. But for now, I will leave it here. Next week I will give a list of my top KNF recipes and how you should consider going about making your own nutrients. In the meantime, use this method to create your own IMO culture in your grow space and step into the world of real organic farming
