Carbon Sequestration

I work on sustainability science (environmental sustainability) with an emphasis on food and nutritional security in climate change context. My current affiliation is with Centre for Oceans, River, Atmosphere and land Sciences (CORAL), Indian Institute of Technology, Kharagpur, India, as a doctoral candidate and working as a visiting scholar at ICRISAT Hyderabad. My research focuses on the comparative assessments of conventional and new flanged concepts to sequester carbon in soil and analysing its effect on soil carbon fractions, crop production, soil fertility and potential emissions arising from chemical fertilizer use in soil.

Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. My research integrates scientific principles from soil science, agronomy, biology, and chemistry to elucidate how soils provide essential ecosystem services. My research also provides an understanding of how soil properties relate to and can be managed for optimal agricultural production, and agro-waste disposal and management. I address nutrient management, sustainable agriculture, soil biogeochemical cycles and climate change.

We build on soil as well as with it and in it. Soil plays a vital role in the Earth's ecosystem. I also work on designing and production of biochar based on the need of soil. Being an agricultural systems researcher by training my focus is on agroecology and environmental footprints of agriculture. I have experience of working with crop simulation models on DSSAT platform and DNDC. Advances in watershed, natural resource, and environmental sciences have shown that soil is the foundation of basic ecosystem function. Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.

As our awareness of the value of natural and managed ecosystems services grows, new biodiversity, carbon, and water markets are emerging, such as the Chicago Climate Exchange, and the nutrient trading programs under the new executive order on the Protection and Restoration of the Chesapeake Bay. These markets place an economic value on management practices which increase those ecosystem services, producing goods that enhance human and environmental health.

Objectives

• Preparation, characterization and comparative evaluation of biochar with compost for soil nutrient dynamics
• Effect of biochar biofertilizer as compared to conventional organic and inorganic nutrient management in rice and maize
• Evaluation of residual effect of biochar and compost fertilizers on legume yield

Importance

• To improve soil organic carbon and soil fertility for food security
• To promote use of agro-residues and avoid their wasteful burning
