Poultry litter provides an important source of plant nutrients including nitrogen, phosphorus, potassium, calcium, magnesium and sulphur. The potential for phosphorus (P) surplus at the farm scale can increase when farming systems change from cropping to intensive poultry and animal production, as P inputs become dominated by poultry and animal feed rather than fertilizer. Cost-effective and innovative solutions are needed to expand the range of acceptable options in the management of nutrients, especially P in poultry manure. This will involve refining feed rations, using feed additives to increase P absorption, managing P in the manure, moving manure from surplus to deficit areas, finding alternative uses for manure, and targeting conservation practices to critical areas of P export during land application. This paper gives an overview of various strategies used in managing P in poultry manure in relation to its disposal through land application.
