This paper comprises the results of two experiments in successive to evaluate the fate of chlorine radicals of ammonium chloride in the field conditions. Rice was used as the first test plant, followed by soybean as a succeeding crop. Ammonium sulphate and urea at rates of 8 and 16 kg N/rai were used as standard fertilizer, of which both are effective sources of nitrogen for paddy. The yields obtained from ammonium chloride were somewhat similar to those of the commonly used nitrogen fertilizer. Higher rates of these three nitrogen fertilizers gave higher grain yields. The radioactive Chlorine, Cl, made it possible to trace chlorine radicals in the plant top and its residual distribution in the soil profile prior to growing the second crop. The results indicated that chlorine content in rice markedly increased with increasing rate of ammonium chloride fertilizer application when compared to the plant receiving ammonium sulphate and urea. Residual chlorine from fertilizer after growing rice showed no effect to soybean
