Summary
Rice yield in various improved acid sulphate soils
To get yield of 6.0 ta/ha/crop, to alleviate toxicity, leaching water should be the first ranking measure. Amount of fertilizer use: 7-10 kg P2O5/ha/crop in well improved thionic fluvisols, or 50-70 kg K2O/ha/crop in light improved thionic fluvisols.
