Abstract

Research and estimation have been carried out on a mechanism to generate methane in paddy fields, which relates closely to global warming. For methane flux measurement, the chamber method was used. The result revealed that with paddy fields mixed with organic substances, methane generation was abundant in the order of raw rice straw mixed area > rice straw compost mixed area > chemical fertilizer mixed area. At the Ryugasaki test area, the raw rice straw and fertilizer mixed areas have generated methane annually at 27.0 gm[sup [minus]2] and 8.2 gm[sup [minus]2], respectively. With regard to soil types, the order was peat soil > gley soil > Kuroboku soil > light-colored Kuroboku soil, where the peat soil generated about 40 times as much of methane as the light-colored Kuroboku soil. As regards the influence from drainage adjustment, normally water-filled field, wet field, and dry field generated methane at 9.25, 4.79, and 0.34 gm[sup [minus]1] y[sup [minus]1], respectively. Amount of methane generated annually from paddy fields over the whole world was estimated at 22 to 73[times]10[sup 12] g. It was determined from the above facts that methane generation may be reduced if organic substance mixing and water in paddy fields are controlled  More>>
