The relationship between drainage water chemistry and soil properties
Soil drainage is a natural process. Soil stores the largest terrestrial pool of organic carbon and can act as a source and/or filter for water pollutants like nitrogen. Meanwhile, fine soil particles play a crucial role in the stability of carbon and nutrients in soil. Even a few decades of increased drainage, due to subsurface drainage installation, can change the proportion and composition of fine soil particles closest to the drain. What happens if there is increased precipitation, and thus increased soil water flux? How does this impact the mineral composition and carbon and nutrient stability in soil? The EU-funded IDESoWa project will search for answers. It will calculate soil element fluxes within soil and their losses with drainage water.
