Conservation of soil ecosystem by arresting land degradation, preventing soil errosion and maintaining health of soil for sustainable agricultureculture and food security

Land and soil media are monopolistic and significant Agro-Eco system for Agriculture production. On the advent of green revolution, the information on natural resources is not utilized in true sense for intensification Agriculture. As result, the country has witnessed mass degradation of land resources. Present estimate indicates about 121 million Hectares Land (39% of total geographic area) is affected by various kinds of degradation (ICAR 2010), of the total degraded land 55 mh is waste land and 6.6 mh is salt affected area. 64 mh of net cultivable lands are prone to affected by one or the other kind of degradation (NBSS- LUP 2015). Deficiency of microflora and secondary nutrients is increasing rapidly, which results in bad health of soil and fertility. Different degradation process occurring alone or in combination are one of reason for declining total agriculture productivity particularly in irrigated lands. According to Agro – ecological survey (AES -2016), quantified that the area under semi aerid type of Bio-climate is increased and the area under Humid type of Bio climate is decreased.
