Abstract: Loessial soil is the major type of cultivated land in the loess hilly and gully area of northern Shaanxi. It has a thick soil layer which can store a large amount of rainwater. It acts as the “moisture reservoir” vital for crop growth on dry land. However, due to lack of rainfall and soil nutrients caused by soil erosion, the productivity of loessial soil has to be improved through artificial means, an important one of which is soil fertilization. In order to explore the effects of continuous application of chemical fertilizer to crops, the Ansai National Field Scientific Observation and Research Station has carried out continuous fertilization Experimentation on different land types of loessial soil in the hilly and gully area of loess since 1980’s. The experimentation has been carried out in tableland, terrace and slope fields. This paper presents a dataset of soil moisture under continuous application of varied fertilizer combinations from 1997 to 2011. For its good continuity and reliable quality, the dataset can support research on soil nutrients.
