Abstract
We studied the effect of lime and organic fertilizer (mamure and soybean cake) on mineral pollution soils, and the results summerised as follows. (1) The mineral pollution soils were almot acidic, so that lime has been Suitable effect to control of its, but on paddy rice, excess of lime were decrease its products. There seems that soil reaction be come too alkaline to paddy rice growing. The suitabble quantity of lime to be concider about 3 kan per a. (2) Organic fertizer as manure and soybean cake not profit to paddy rice on mineral pollution soil, especially the case of exist of sulphide. But on barley not deleterious effect so paddy rice but increase its production.
