Decomposition of organic residues in soil in relation to mineralisation of carbon and nutrient availability
1981
Agyekum, S.F.
Two organic residues, farmyard manure (F.Y.M.) and paddy rice straw were incorporated in soil and incubated for 120 days to evaluate their rate of decomposition, pattern of nutrient mineralisation, and efficiency as soil organic matter builder. The rate of CO2 evolution was higher within the first 48 hrs of incubation. F.Y.M. was better material as soil organic matter builder. As supplier of N, P and K to the immediate next crop, the efficiencies of organic materials are in the order for N, FYM straw, for P, FYM straw, for K, straw FYM. Straw maintained nitrate depression throughout the period of incubation
