Biochar created from poultry litter is a way to produce a value added soil amendment that isrich in nutrients and locally, but effects on crops and soil properties are unknown. The effect of poultry litter application was studied on a degraded soil to determine its optimum rate enhancing growth and yield of corn and evaluate its effect on the soil physico-chemical properties. Five treatments using 0, 2.5, 5, 10, 20 tons of poultry litter char per hectare were used in a randomized complete block design (RCBD) with three replications. The study showed that poultry litter char is a valuable organic fertilizer and can serve as a suitable alternative to chemical fertilizer in the Philippines. Poultry litter char treatments significantly increased the plant height, resulted to earlier tasseling, fruiting and harvesting of corn and increased their yield particularly number of fruits, fruit yield, ear length, weight of 1000 seeds and stover yield as well. On the other hand, addition of poultry litter char significantly improved the physico-chemical properties of degraded soil such as reduction of soil strength, increased porosity and water holding capacity, increased pH, % OC, total N, Extractable P, Exchangeable K and Ca. The study recommends an application rate 20 tons per hectare on this type of soil to improve the growth and yield of corn and properties of degraded soil
