How to reduce greenhouse gas emissions from organic matter amended soil?

  • 13.Climate action
  • 2.Zero hunger
  • 12.Responsible consumption, production
  • 15.Life on land

Background

   Agriculture is responsible for emissions of greenhouse gases such as carbon dioxide (CO2) and nitrous oxide (N2O). Production of these gases in farmland soil results from biological processes like organic matter decomposition, nitrification and denitrification, and highly depends on organic matter inputs. We aim at analyzing effects of organic matter amendment on CO2 and N2O emissions. In particular, we are interested in agricultural soil amended with livestock compost.

Expected results

   We can propose the best organic matter management practices in rural areas according to scientific data analysis using new technologies.

Inputs of organic matter are essential to maintain soil quality. In the greenhouse, rice husk was incorporated into the soil for soil fertility maintenance.
Rice bran and corn with more easily decomposable C enhanced N2O emissions for the first 12 h, whereas N2O emission rates reduced towards 72 h
