Climate-smart agriculture practice brief: Integrated manure management

Manure Practice brief

Overview of Integrated Manure Management

The key benefit of Integrated Manure Management is the prevention of nutrient losses as much as possible under the site-specific circumstances, while reducing greenhouse gas emissions and improving food security. Manure discharge should be prevented at all times.

The overall nitrogen losses from manure are estimated at approx. 40% (IPCC, 2006). Most nitrogen is lost as ammonia (volatilization) and nitrate (leaching and run-off). A 40% loss of a total of 70 million tonnes of nitrogen applied to soils (including pastures) with manure from swine, poultry and cattle, implies the loss of approx. 28 million tonnes of nitrogen; which accounts for about a quarter of the total nitrogen use with synthetic fertilisers (FAO, 2016).
