Abstract:

Modern agriculture, no doubt has paved the way for “Green Revolution”, but it has led to the application of heavy doses of chemical fertilizers and pesticides with the sole objective of maximizing the yield. The unbalanced and continuous use of chemical fertilizers in intensive cropping system is causing deterioration of soil health, multi-nutrient deficiencies, low productivity, poor quality and environmental hazards. Poor quality of food and fodder has caused serious health problems and disorders in both animals and human beings. Now, the agriculture research is focused on evolving ecologically sound, biologically sustainable and socio economically viable technologies like organic farming which includes local organic sources of nutrients without using chemical fertilizers and pesticides. Adoption of organic farming minimizes the environmental pollution and maintain long-term soil fertility by improving soil organic matter and essential plant nutrients including secondary and micronutrients. For producing quality food by sustaining the soil productivity and soil health are the challenges before us on one side and minimizing the pressure on non renewable sources or limited available sources on other hand needs immediate attention by all the stakeholders engaged in agriculture. Application of technologies available in organic farming and use of all locally available organic sources particularly on farm biomass which are rich in secondary and micronutrients will meet the twin objective of quality food production and reducing the pressure on non renewable resources.
