Agricultural Depletion of Soil Nutrient in Arable Land

Abstract

Land degradation is a concept in which the value of the biophysical environment is affected by one more combination of human induced processes acting upon the land. Soil is the essence of life. Agriculturally soil is a region supporting plant life and from which plants obtain their mechanical support and many of their nutrients. As Indian economy is agricultural based, so to ascertain the role of nutrient in soil fertility and plant growth, this base line survey was undertaken. In our country crop production is far below than population density, resulting in large shortage of food stuff. It is estimated that up to 40% of world’s agricultural land is seriously degraded. Integrated plan nutrient management (IIPNM) adopted scientifically to ensure greater sustainability in agricultural development which combines economic and efficient traditional and frontier technologies to gain from the symbiosis and synergy of crop soil environment biointeractions.

Key words - : arable, nutrients, solvent extraction, depletion.
