Effects of agricultural management on greenhouse gas emissions, carbon and nitrogen sequestration, and DAYCENT simulation accuracy
Agricultural activities affect greenhouse gases (GHGs) sources and sinks in terrestrial ecosystems. Organic fertilizer provides nitrogen (N) and organic carbon (C) to soil, resulting in enhanced N and C substrates for nitrification and denitrification which produce nitrous oxide (N2O) and for heterotrophic activity which generates carbon dioxide (CO2). Therefore, reduction of N and C substrates for N2O and CO2 production can reduce these emissions. Proper organic fertilizer application can regulate or reduce the loss of N2O from soil. In addition to reducing GHG production, increasing the potential ...
