Soil and Its Importance

Soil is a fundamental component of food production, providing essential media for crop cultivation. Soil organic carbon (SOC) is a key parameter for agricultural soils,ensuring food security and sustainability. It plays a critical role in the global carbon budget and sequestration. The soil microbial community, including bacteria, archaea, viruses, algae, fungi, and protists, significantly influences soil functions by regulating plant growth through nutrient cycling.

Research and Innovation

To address climate change issues, there is a growing interest in managing soils and plants to increase SOC and reduce GHGs emissions. However, measuring and monitoring SOC is challenging due to its complex interactions with climate, land use, and management practices. Effective strategies require reliable measurement, monitoring, reporting, and verification (MMRV) systems. 

Project Goals

The proposal aims to develop innovative strategies to reduce GHG emissions and enhance soil carbon sequestration without compromising crop yields. An integrated approach will be used to: 

  • Quantify GHG emissions and carbon sequestration using innovative technologies. 

  • Investigate the role of microbes in carbon sequestration. 

  • Develop innovative additives, such as hydrogels and biochar, to increase carbon capture. 

Experimental Approach

Experiments will be conducted on six plots using commercially available hydrogels and biochar in pasture and cropland ecosystems. The impact of these amendments on carbon sequestration will be monitored. GHG emissions will be quantified, and plant growth trials will be performed in a greenhouse setting. Advanced tools, such as soil and water quality sensors, automated soil CO₂ multiplexers, and high-resolution satellite data, will be utilized.

Data Collection and Analysis

Soil samples will be collected at various depths (0-15cm, 15-30cm, 30-100cm) and analyzed using ICP-OES, CHNS, and TOC analyzers. Research findings will be shared and presented locally, nationally, and internationally. 

This project aims to develop novel, cost-effective soil amendments and MMRV systems to enhance soil carbon sequestration, contributing to climate change mitigation and sustainable agriculture.

Labs and Equipment

Eddy Covariance Flux Tower (‘Flux Tower’)
An Eddy Covariance Flux Tower is a sophisticated instrument used in environmental and agricultural research to measure and analyze the exchange of gases, such as carbon dioxide (CO₂), water vapor, and other trace gases, between the Earth’s surface and the atmosphere. The data collected provides valuable insights into ecosystem dynamics, carbon cycling, and energy fluxes in various environments, including agricultural fields.
