The Implications of Animal Manure Management on Ammonia and Greenhouse Gas Emissions

Abstract

High livestock densities and the subsequent generation of large quantities of manure, in some areas of the world, generate hotspots of increased environmental risks through ammonia (NH₃) and greenhouse gas (methane, CH₄; nitrous oxide, N₂O) emissions. Livestock production is therefore facing increased pressures from society to comply with environmental legislation, so that production systems are managed in a sustainable and environmentally friendly manner. A key solution to minimize or avoid environmental and health concerns associated with manure is to ensure appropriate feeding strategies as well as manure management techniques through the entire manure management chain from animal housing, storage of manure, treatment operations and finally application to soil. An integrated framework is needed to allow practical, cost-effective on-farm strategies to be selected, which will reduce losses and improve resource use efficiencies.

In this chapter, we first analyse the contribution of manure management to NH₃ and GHG emissions with focus on bovine, pig and poultry manure. We then describe different mitigation options for reducing gaseous emissions along the manure management chain in terms of their efficiency to decrease NH₃ and GHG emissions and their applicability. Finally, we present and assess two case studies of integrated manure management strategies to reduce gaseous emissions.
