The laboratory are equipped with highly sophisticated analytical instruments (Semi Automatic Nitrogen Analyzer, Double beam UV-VIs Spectrophotometer, Flame Photometer, Atomic Absorption Spectrophotometer coupled with Hydride Generator, ASTM, Chlorophyll Meter, Tensiometer, Pipette Apparatus, BOD shaker incubator, Laminar Flow) for evaluation of physical, chemical and biological parameters of the samples to farmers and other private organizations on payment basis. Based on the soil testing results, fertilizer recommendation is provided to the farmers to meet the crop specific nutrient management system for better soil health and enhancing economic return to farmers.
