%X Tillage can largely reduce the soil CH 4 sink becaus e of its long inhibition on soil CH 4 uptake. Ammonium can inhibit CH 4 oxidatio n in the soil but nitrate can not do that. The effect of ammonium inhibition on soil CH 4 oxidation is better than the manure with the same amount of nitrogen as ammonium. Crop residue that has small C/N ratio or can lead to soil acidifica tion has a large inhibition on soil CH 4 oxidation. Biowaste compost has a shor t-term inhibition on soil CH 4 oxidation. Irrigation and the use of pesticide c an decrease the soil CH 4 uptake. No-tillage,application of ammonium and organ ic fertilizer are the available measures to remain or increase the potential of CH 4 uptake in arable soil.
