摘要

Decreased soil fertility represents a major constraint towards agricultural production and food security in farming. As farmers are unable to massively invest in fertilizers, they use green manure to compensate for this. This study was carried out in an experimental farm and laboratory of Inst. of Sustainable Agrotechnology, University Malaysia Perlis, Padang Besar, Perlis, Malaysia to determine the optimal time for decomposition and nutrient release from green manure legume (mungbean residue) in a tropical soil. The treatments involved four decomposition duration of 0, 1, 2, and 4 weeks after its incorporation. They are laid out in a Randomized Complete Block Design (RCBD) with five replications. The content of nitrogen (N) decreased, while other elements increased during decomposition. Organic matter content (OM) increased from 2.10% (non-treated) to 2.50, 2.65, and 2.60% after 1, 2, and 4 weeks of incubation, respectively. The content of P increased by 60 mg kg-1 when treated for two weeks. The contents of potassium (K), magnesium (Mg), cation exchange capacity (CEC), organic carbon (OC) and carbon to nitrogen (C:N) ratio were all significantly influenced by periods of incubation. The pH of the soil also increased after four weeks of incubation.
