Abstract :Abstract   Biochar created from poultry litter is a way to produce a value- added soil amendment that is lighter and less expensive to transport out of manure nutrient excess areas but its effects on nutrient availability are less known. A pot experiment was conducted to: 1); evaluate the phosphorus availability and growth performance of corn applied with poultry litter char grown in degraded soil. 2); determine the optimum rate of poultry litter char as amendment for corn in degraded soil. There were four treatments with four rates of PLC application insert ignore into journalissuearticles values(T1-0g kg -1 soil; T2-200g kg -1 soil, T3 - 400g kg -1 soil and T4 - 60g PLC kg -1 soil);. Each treatment was replicated four times and arranged in Randomized Complete Block Design insert ignore into journalissuearticles values(RCBD);. Corn plants were used as a test crop for nutrient availability. Planting was done after 10 days of incubation of soil and poultry litter char mixture for reaction. Plants were harvested 30 days after planting for soil and tissue analysis. Results revealed that addition of poultry litter char enhances phosphorus availability and better growth performance. Generally, addition of increasing rates insert ignore into journalissuearticles values(20-60g kg -1 soil); of PLC resulted in consistent increase on weekly plant height, pH H2O , %OC, and extractable P of soil after harvest. On the other hand, similar increasing trend was observed in the soil extractable P within 10 days of incubation before planting. Tissue P concentration were increased after addition of increasing rates of PLC. However, there were no significant differences observed between the rates of PLC. Dry matter yield was also significantly increased with increasing the rates of PLC addition.
