Abstract:
Tillage can largely reduce the soil CH
4 sink because of its long inhibition on soil CH
4 uptake.Ammonium can inhibit CH
4 oxidation in the soi1 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 acidification has a large inhibition on soll CH
4 oxidation.Biowaste compost has a short-term inhibition on soll CH
4 oxidation.Irrigation and the use of pesticide can decrease the soil CK,uptake.No-tillage,application of ammonium and organic fertilizer are the available measures to remain or increase the potential of CH
4 uptake in arable soil.
