Abstract

Winter cover crops are cultivated during cold fallow season in temperate countries for green manure and animal feed. Literature on incorporated biomass composition in relation to soil respiration like CH4-C and CO2-C is not available. Therefore, soil respiration as affected by variable biomass composition was determined from paddy soil. Soil respiration rate (1280-1341 kg ha-1) was significant when 197 and 204 day-old plants were incorporated. The CH4–C and CO2-C respiration rates were significantly correlated with cellulose, lignin, protein, and ash. However, CH4-C respiration was negatively related with CO2-C respiration. These implies that biomass composition is influenced by age of cover crops that ultimately dictates paddy soil respiration rates.

Key words: Rice field, biomass composition, age of biomass, CH4-C, CO2-C.
