The technology of laser land leveling can improve the accuracy of land leveling and it is the important measure of improving irrigation efficiency and facilitating more uniform distribution of irrigation water. The technology is more widely used in China in recent years. As the work process of laser land leveling machine can result in disturbances of cultivated horizon, the chemical properties may be changed ,and the case will have an impact on crop yields. But, few studies have been conducted to characterize the impact on soil productivity after using laser land leveling in China. The objective of this study was to evaluate application effect of laser land leveling in yellow heavy loam region. The study to carry out a experiment of laser land leveling by using the machine developed by ourselves in Shanxi province. A grid-sampling approach was used to collect soil samples of pre- and postleveling, and the contents of organic matter, P, K, AN (available nitrogen), TN£¨total nitrogen£©in the top 20cm was analyzed. The study evaluated the impact on soil productivity after using laser land leveling through analyzed the contents change and spatial transfer of organic matter, P, K, AN, TN. Results of this study demonstrate that the contents of AN significantly decreased, the others have a little decreased. Laser land leveling will has short-term impact on soil productivity in the region, Further research is required to ascertain long-term effects of laser land leveling in the region, so as to provide a reference for application of laser land leveling and postleveling management in the similar areas in China.
