Kyusei Nature Farming, which was started by Mokichi Okada, is another method of organic farming, though it differs a bit from the previously discussed Natural Farming Method. Kyusei Nature Farming, unlike the Natural Farming Method, does not prohibit tilling or weeding, however it does also try to encourage a more natural approach to agriculture.  Mostly, the Kyusei Nature Farming is very similar to any ordinary organic farming method except for one thing: it is often used in conjunction with Effective Microorganisms (EM).

The concept of beneficial Effective Microorganisms was first developed by Teruo Higa from the University of the Ryukyus in Okinawa, Japan around the 1980s. From his research, he reports that there are certain microorganisms that when used in farming, can positively affect numerous parameters. He found this group of beneficial organisms to contain lactic acid bacteria, photosynthetic bacteria, ray fungi, yeasts and mycorrhizal fungi. In his research, Higa claims that these organisms, in mixed cultures through fermentation reactions, produce organic acids, plant hormones, vitamins and antibiotics. They also did many things that were beneficial to the growing crops. For example, they dissolved nutrients that are often difficult to dissolve (such as rock phosphate), bound heavy metals to prevent the uptake by plants, provided organic molecules for plant consumption, protected crops from pathogens, insects and diseases, stimulated plant growth, and improved the properties of the soil.

For the EM to work optimally, the soil pH must be adjusted to around 6 or 6.5, the soil must be kept moist, a humus content of about 3% must be maintained, and EM must be diluted to about 1:1000.

There has been some debate as to the validity of the claims, and even Higa himself admitted the main issue is the lack of reproducibility and inconsistent results. He went on to say the most difficult aspects of using EM is one must understand the nutritional and environmental requirements of the microorganism as well as its interactions with the environment and other microorganisms very well, which is still being investigated.

Nonetheless, EM is now being researched further, as it could be a promising new addition to organic agriculture. It could allow us to increase productivity while not having to use fertilizers or pesticides. In a paper by Myint Lwini and S. L. Ranamukhaarachchi that talks about controlling wilt disease, it was shown that the most effective bio-control for the disease was EM. Even more, other experiments have been done by numerous individuals that tested the effect of EM use on yield of crops. These studies usually found that there is an increase in crop yield when EM is used.

It seems EM may be a great new way to boost organic agriculture. For the past few years, EM has even used for composting residential waste in Christchurch, New Zealand. The local city council backs EM and is beginning to conduct local research for use as an organic fertilizer.
