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 (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 (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 (20-60g kg-1
soil) of PLC resulted in consistent increase on weekly plant height, pHH2O,
%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.
