There is no doubt that, green revolution technologies have revolutionized the food production scenario and transformed the Indian agriculture from subsistence to surplus generating enterprise. But indiscriminate use of chemical inputs (fertilizers, pesticides and hormones) and over-exploitation of natural resources led to decline in soil health and fertility, depleting natural resources and contamination in environment, water and food. All these concerns have underscored the need for exploring alternative agricultural systems, that are sustainable, environment friendly, non-degrading, non-contaminating and offer better income opportunities to the farmers along with safe and healthy food to citizens.

Non-chemical natural farming systems which rely largely on biomass recycling, biological rejuvenation of natural nutrient cycles and promote usage of on-farm plant and livestock-based inputs are being used with considerable success in various parts of the country by individual practitioners. Such natural farming systems, besides being sustainable, non-degrading, non-depleting and resource conserving are also low cost. They give freedom to farmers from purchased inputs, ensure comparable productivity, increased income and are safe to soil, environment and all the life forms including human and animals.

Adoption of natural farming practices on farmer fields have been found to be enriching the soils with organic carbon, increased microbial activity, increased activity of earthworms leading to restoration of natural nutrient cycles, improved water holding capacity and increased biological activity. Natural farming fields with adequate diversity have been found to be less prone to insect pest attacks.
