Description:	Determining optimal poultry litter (PL) application rates for long term use is challenging due to the poorly characterized effect of antecedent applications on soil fertility, especially in organic grain systems where livestock manures which provide multiple nutrients in ratios different than crop needs are often a dominant nutrient input. Evidence from the long term Farming Systems Project (FSP) in Beltsville, Maryland, USA (established 1996) suggests that repeated applications of PL at University recommended rates especially in shorter rotations are greater than optimal to meet agronomic and environmental goals of sustainability (Table 1).
