The test, demonstration and research on rice and the results indicated that the technology about precise application of nitrogen can save nitrogenous fertilizer, increase utilization efficiency, increase the yield, reduce pollution and protect the environment of soil. From the test we knew the precise application can save the nitrogenous fertilizer by 4.9 kg/667 m2, increase the yield by 30 kg/667 m2, improve the efficiency of nitrogenous fertilizer by 6.5%.
