Soil Fertility Assessment, Mapping And Fertilizer Recommendation through Geospatial Approach

Not AvailableFood production in India witnessed an unprecedented increase over the last four decades. It bounced from nearly 71 million tonnes during 1960’s to 247.6 million tonnes during 2010’s. This achievement was mainly the resultant of intensification of agriculture rather than contribution from the marginally increased (135 to 145 m. ha) land over the same period. But in the process, it caused soil exhaustion especially through depleted plant nutrients. Because of imbalanced and inadequate fertilizer use coupled with lower input efficiency, the response (production) efficiency of chemical fertilizer has declined tremendously under intensive agriculture in recent years. Soil characterization in relation to soil fertility status is an important aspect in sustaining agriculture production. However exploitative nature of modern agriculture involving use of high analysis N P K fertilizers coupled with limited use of organic manures and less recycling of crop residues are important factors contributing towards accelerated exhaustion of micronutrients from soil. As seen, deficiency of micronutrients has become a major constraint for productivity, stability and sustainability in many Indian soils.Not Availabl
