Contributions of selected animal manure and common farming and soil fertility management practices to soil organic carbon status and greenhouse gas mitigation in Ogbomoso, southwestern Nigeria: In: Unraveling the contributions of the Nigerian Livestock and other more prominent sectors in mitigation of global greenhouse gases.

Agricultural activities is a major anthropological driver for greenhouse gas emissions in the world of which crop and livestock production account for more than half of the total emissions. Agricultural activities can significantly contribute to and/or mitigate soil organic carbon depletion and greenhouse gas emissions depending on how sustainable the prevailing farming practices are. This review revealed indiscriminate use of agro-chemicals dominantly chemical fertilizers and herbicides to be major drivers for soil organic carbon depletion and greenhouse emissions in Nigerian soils. Poultry manure application could be a blessing and woe to our soils depending on its mode of application into the soils. Its application in almost raw form significantly contributed to enhanced CO2 emissions, nutrient leaching and environmental pollution. Modifications of poultry manure through aerobic decomposition into compost and thermo-chemical conversion into biochar are sustainable means to putting poultry manure to use to the advantage of the environment.
