Livestock manure contributes 30-50% to global nitrous oxide (N2O) emissions from agriculture (where ammonia (NH3) is an indirect source of (N2O)), and 10-40% of total agricultural methane (CH4) emissions for most countries.
Improve our understanding of the influence of key variables (incl. manure type, climate & soil conditions) affecting N2O, NH3 and CH4 emissions from manure management
