| Description | The decomposition processes of intact rice residue (leaf blades) in Maahas soil of the Philippines were investigated by incubation experiments at 30°C. The experiments dealt with nitrogen immobilization by rice residue under lowland and upland conditions. Rice residue which is low in nitrogen. absorbed nitrogen from the soil and from the added fertilizer (ammonium sulfate) during its decomposition under both conditions. Under lowland conditions, the amount of nitrogen immobilized was small during the first week but became large after 2 or 3 weeks. Under upland conditions the immobilized nitrogen reached its maximum during the first week but the amount was not so large as under lowland conditions. The added fertilizer stimulated decrease of weight of the rice residue early in the incubation period but retarded it later under both conditions. The absorption of fertilizer by rice residue ceased at the early stage of the residue decomposition, but the nitrogen content of the residue continued to increase. |
