Land application of broiler litter is a common disposal method due to its value as a fertilizer substitute, but presents potential environmental problems because of nutrient runoff. Composting has been suggested as an alternative due to the formation of more stable organic components. The land application of fresh and composted broiler litter are compared as alternative disposal methods. The costs of land application of broiler litter are dominated by spreading because of low nutrient densities relative to commercial fertilizers. Composting broiler litter before land application appears to be substantially less economically attractive than land application of fresh broiler litter because of high costs of production and higher spreading costs due to even lower nutrient density. However, when environmental constraints are placed on the phosphorus concentration from hayfield runoff, composting becomes a more attractive alternative. Composting becomes more viable as the land base for application becomes smaller relative to broiler production; as alternative disposal costs for litter become higher; and as environmental constraints become stricter.
