It has been observed in the previous investigation, that the rate of CN2, HCN2 ions remowal were more rapid from an acid soil with high buffer capacity, and the toxicity thus induced by this fertilizer may be accordingly reduced. It was also stated that for a soil with high exchange capacity, high percentage of base unsaturation and high lime requirement value, a greater effect through the application of calcium cyanamide may be expected. In the present investigation, both field and pot experiments of rice with various treatments of calcium cyanamide and sulfate of ammonia, as shown in Table 3, were made with three acid soils and one alkali soil. The physical and chemical properties of these soils are tabulated in Table 1 and 2.
