Description

This CRP will explore potential farming practices under different agro-ecosystems to enhance soil carbon accumulation-sequestration and reduce greenhouse gas (GHG) emission. Its main objectives are to (i) develop land management practices for reducing soil carbon depletion and enhancing soil carbon and nitrogen capture and storage, (ii) identify factors that influence GHG emissions from farmlands, and (iii) develop soil-water-nutrient management guidelines to   enhance soil carbon and nitrogen capture and storage. Stable isotopic signatures of nitrogen-15 and carbon-13 will be used to identify sources of  carbon dioxide (CO2) and nitrous oxide (N2O) emission and accumulation of carbon and nitrogen under different land uses

Objectives

To mitigate nitrous oxide emissions and minimise nitrogen losses from agricultural systems whilst enhancing agricultural productivity and sequestering soil C.

Specific objectives

To quantify N2 and N2O emissions simultaneously using 15N technique in selected agricultural systems

To quantify N2O emissions only in agricultural systems

To quantify soil nitrogen transformation rates (using 15N) and to assess efficiency of N process inhibitors/biochar used to manipulate them

To specify and test mitigation options (N process inhibitors/biochar) to decrease N2O fluxes to atmosphere
