About

Currently engaged in R&D planning and monitoring of ICAR-Agricultural Technology Application Research Institute (ATARI), Kolkata and 59 KVKs across West Bengal, Odisha and the Andaman & Nicobar Islands. Spearheaded GPS/GIS-based soil fertility mapping and nutrient plans for 173 districts across 20 states. Developed STCR-based nutrient strategies for dryland agriculture, soil quality indices, bio-amelioration for salt-affected soils, MIR spectroscopy based algorithm for soil health assessment and wastewater use in non-food crops. Quantified carbon sequestration in alkali and sodic soils under diversified systems and advanced conservation agriculture strategies in reclaimed lands.
Patent granted: Two (#347189 & 572808) and Commercialized; Software Copyrights: Five (Registration No. SW-14310/2021; SW-18892/2024; SW-19621/2024; SW-19646/2024; SW-2025022050). Developed and nationally adopted two ICAR-certified extension models: the Impactful Model for Farmer FIRST Programme (ICAR-AEXT-NAARM-Model-2024-083) and the Rural Agripreneurship Incubation Centre (AIC) Model for Youth (ICAR-AEXT-ATARIPAT-Model-2024-035). The Mridaparikshak technology was commercialized nationally, contributing over 15% of Soil Health Cards under the GoI scheme, earning ICAR-IISS over ₹4 crore in royalty.
Executed 64 research projects, including 22 in-house projects, 21 projects of National Importance including 2 consultancy projects, 21 externally funded. Built STCR labs in 21 universities and 4 ICAR institutes; led 217 capacity-building programs for 12,047 tribal farmers and conducted over 6,000 FLDs showcasing STCR benefits. Delivered 16 TV and 14 radio talks on agri-technologies.
