title: Soil Moisture Profile Dataset of Wheat-Millet-Corn Rotation (2023–2024) in Loess Plateau
title: 黄土高原小麦-糜子-玉米轮作土壤水分剖面数据集（2023–2024年）

description: This data set was derived from the long-term rotation fertilization experiment of Changwu Loess Plateau Agricultural Ecological Experiment Station (107°40′30″E,35°12′30″N) of the Institute of Water and Soil Conservation of the Ministry of Water Resources, Chinese Academy of Sciences. The experiment located in a typical dryland agricultural area on the Loess Plateau, with a semi-arid continental monsoon climate. The dataset was based on the wheat-millet-corn rotation system and recorded the dynamics of soil moisture, temperature and electrical conductivity at the rootzone profile (20 cm, 40 cm, 60 cm, 80 cm and 100 cm) from 2023 to 2024, with a total of 500 data points. CR800 data collector combined with RS-WS790 three parameter sensor were used for continuous automatic monitoring, and then the data were calculated as daily average. For data quality verification, drying method was used to measure the soil moisture and the thermometer was used to measure the temperature of the plow layer. The dataset fully presents the temporal variation patterns of soil water, heat and salt parameters at different soil depths. This dataset provides direct observational evidence for studying the changes in the microenvironment of farmland soil profiles in the Loess Plateau region and evaluating the coupled transport mechanism of water, heat and salt at different soil depths. It is of great significance for deepening the research on efficient water utilization and soil health management in dryland agricultural ecosystems.
