Abstract: Loessial soil is the main cultivated one in the Loess hilly and gully area of Northern Shaanxi. It is characterized by deep soil layer, which can store a large amount of rainwater. It is called the soil reservoir for the growth of dry land crops. However, due to the lack of rainfall and the lack of soil nutrients caused by soil erosion, soil fertilization has become an important measure to improve the productivity of loessial soil. In order to explore the effects of continuous application of chemical fertilizer to crops, Ansai National Field Scientific Observation and Research Station has carried out the Continuous Fertilization Experiment of different land types of loessial soil in the hilly and gully area of loess since 1980’s. The experiment has been carried out in tableland, terrace and slope fields. In this paper, the dataset of soil moisture in the experiment of continuous application of different fertilizer combinations from 1997 to 2011 was collected. The dataset continuity is good, the quality is reliable, it will supports the important soil nutrient basic data for further studies.
