Few studies have examined the use of poultry litter as an alternative to inorganic P and K fertilizers for flood-irrigated rice. The objective of this study was to compare fresh and pelletized poultry litter to inorganic P and K fertilizers to document the availability of P and K in poultry litter. Inorganic P and K fertilizers, fresh broiler litter, and pelletized litter were preplant-incorpor...
