Abstract

Soil hydro-physics (SHP) properties are the key properties that determine soil–water interactions. As water is the primary transport medium for dissolved compounds, such as nitrogen, phosphates, pesticides, antibiotics, organic matter, etc., SHP properties are also important for the transport behaviour of these substances. Examples of these properties are water retention, saturated/unsaturated hydraulic conductivity, shrinkage and swelling, organic matter content, texture (particle distribution), structure (soil aggregation/pore structure), density and capillary rise. SHP properties are determinants in research areas related to soil-water conditions: food security (drought and water damage), agricultural development (precision drainage, irrigation), soil salinisation and sodification (evaporation and capillary rise equilibrium), soil greenhouse gas emissions (N2O, CO2), nature conservation (wet and dry ecosystem types), sustainable land use and healthy soils (function allocation), water quality (nutrients, contaminants, antibiotics, percolation, leaching and run-off to groundwater and surface water), flooding and ponding (dike stability, infiltration, soil water repellency) and infrastructural damage (soil shrinkage). Given the increasing demand for current data of high quality and the fact that existing databases lack sufficient potential for upscaling, this project serves as a means to generate additional high quality data each year. The SHP properties and related meta information are implemented in the BIS soil information system and from 2021 will be implemented in the Key Register of the Subsurface (BRO) database as well. Currently there are 240 samples linked to profile descriptions and other meta information in the BIS database.
