Utilization of soil water and nitrogen resources in dry land under a long-term fertilizer experiment
旱地长期定位施肥土壤水氮资源利用的研究

Utilization rate of nitrogenous fertilizer and use of deep storage water are studied on the base of a long-term located fertilizer test in this paper.The results show that utilization rate of N is higher in dry land.Lots of N may increase the production and reduce the storage of water.Soil moisture is adjusted by soil reservoir greatly,which is important in drought region.
