The experiment was conducted to see the phosphorus (P) mineralization pattern of bioslurry under aerobic and anaerobic soil conditions. Two bioslurry (cowdung bioslurry and poultry manure bioslurry) and their original manure (cowdung and poultry manure) at 3, 5, 10 and 20 t ha-1, respectively were thoroughly mixed with soil and incubated in aerobic and anaerobic moisture condition for 12 weeks. Among the four different types of manure, P release from poultry manure slurry was the highest. Poultry manure and cowdung slurry recorded very closer amount of available P. Both cowdung slurry and poultry manure slurry released higher amount of P compared to their original state (cowdung and poultry manure). P mineralization reaches in peak within 4-6 weeks of incubation. Under anaerobic condition the P mineralization was found higher compared to aerobic condition. The P mineralization data fitted strongly to the first order kinetic model. The bioslurries had lower rate of mineralization but had higher potentiality to release P in the soil compared to their original state. 

Key words: Bioslurry, cowdung, incubation, phosphorus mineralization, poultry manure
