Manure is organic matter used as organic fertiliser in agriculture. Manure contributes to the fertility of the soil by adding organic matter and nutrients, such as nitrogen that is trapped by bacteria in the soil. As the interest in organic farming and renewable energy production continues to grow, manure is playing an important role in the production of bioenergy, food, and other agricultural products. This book discusses varied topics on the management, uses and environmental impacts of manure, such as: the bioremediational technique of adding nitrite-oxidising bacteria for reducing N2O emission during swine manure composting; improving performance and manure management in the French pig sector; manure management in Africa; phosphorous forms in animal manure and the impact on soil P status; and others.
