摘要：Among the different organic sources which can be used as manure, poultry litter is important as it isrich in major plant nutrients. A laboratory incubation experiment was conducted to study the rate ofcarbon and nitrogen mineralization in soil due to the application of various doses of solid and liquidfermented poultry manure application. The study revealed that the highest carbon dioxide evolution(68.0 mg kg -1 ) and available nitrogen content (63 mg kg -1 ) were present in the soil that received solidfermented poultry manure @ 680 kg ha -1 . The mineralization of carbon (72.8 mg kg -1 ) and the nitrogencontent (64.5 mg kg -1 ) were maximum at 90 th day of incubation. The poultry manure not only addedvaluable plant nutrients to the soil, but also enhanced the mineralization of nutrients. The presentlaboratory study confirmed the increased rate of nutrient mineralization in the soil due to the applicationof various doses of solid and liquid fermented poultry manure.
