  Organic agriculture is best known as a method of agriculture where no synthetic fertilizers and pesticides are used. This description does not mention the essence of this form of agriculture, however, which is the management of farms in such a way that soil fertility and pest problems are prevented. Although many single techniques used in organic agriculture are used in a wide range of agricultural management systems, what differentiates organic agriculture is the focus of the management. Under the organic system, the focus is on maintaining and improving the overall health of the individual farm’s soil-microbe-plant-animal system (a holistic approach), which affects present and future yields. The emphasis in organic agriculture is on using inputs (including knowledge) in a way which encourages the biological processes of available nutrients and defenses against pests, i.e., the resource “nature” is manipulated to encourage processes which help to raise and maintain farm productivity. The soil is a central part of that system. Most fertilizers and pesticides are considered to hinder that process and are, therefore, prohibited. In organic agriculture, management is directed towards preventing problems, while stimulating processes which assist in nutrition and pest management.
  For market purposes, a strict definition of organic agriculture is required to protect both producer and consumer interests. Definitions were first developed in the private sector. The most widely adopted definition was developed and promoted by the International Federal of Organic Agriculture Movements (IFOAM), a non-governmental organization that has existed for 25 years. The IFOAM Principle Aims are used as guidelines for setting standards for organic agriculture in individual countries.
