2025-12-23 Long-term Monitoring Dataset of Soil Nutrient Spatiotemporal Distribution in a typical Mollisols small Watershed doi:10.57760/sciencedb.ecodb.00225 en Long term monitoring and research have been conducted on soil, vegetation, and erosion in a typical black soil small watershed (Guangrong Small Watershed in Hailun City) from 2007 to 2021. We have created a small watershed black soil dataset that includes all factors and time continuity, including soil physical, chemical, and biological factors, crop growth, vegetation coverage, soil erosion modulus, erosion amount, and runoff. To provide basic data support for analyzing the spatiotemporal distribution characteristics, formation mechanisms, and modeling of nutrients in black soil, as well as technological support for soil nutrient, soil quality, and soil health management. Note: The data is raster data and is named according to the rule of "year_0_20cm variable name". The soil properties measured in each batch are not completely the same, so the indicators included in different datasets and years may vary, but they all include TC/SOM, TN, TP, AN, and AP.  Black soil region; Soil properties; Soil ersion Zhang Shaoliang xiao zi liang RESTRICTED dataset http://www.doi.org/10.1007/s12665-014-3081-4 Science Data Bank
