Five Major Contributions
S.No.Major Contribution
1 • Developed natural resource management through mapping and genesis of soils of India, minerals transformation and their applications.
2 • Developed Soil and Land Quality Indicators for Indo-Gangetic Plains and Black Soils Region (BSR) for monitoring and agricultural land use planning.
3 • Identified cropping systems and management of soils that showed increase in soil organic carbon since Green Revolution.
4 • Developed soil organic and inorganic carbon stocks for India and their variability and modelling vis-a-vis effects of global climate change.
5 • Soil and natural resource based agro-technology transfer in different land use systems in NER for doubling farmers income.
