Soil Science

Soil Science

Soil Science division deals with importance of soil and water testing, issue of soil health cards, soil suitability for agriculture, horticulture and soil fertility management strategies to the farming community.

The main objective of this Division is to carry out research on the improvement and maintenance of soil fertility for sustained optimum agricultural production; nutrient requirement  and management of different horticultural crops and to develop suitable INM packages for enhancing productivity; nutrient management through balanced nutrition and increasing nutrient use efficiency; utilization of organic residues (agriculture wastes) as a manure and production of biogas as fuel; soil test crop response correlation studies; utilization of microbes for improvement of crop production and residues management; training and extension of services for students and farming community; advice to the farmers on soil test-based fertilizer recommendations.
