| Abstract/Contents: | "As an increasing amount of European arable land is being set-aside, the impact of non-agricultural vegetation types on freshwater and groundwater formation becomes increasingly important. Terrestrial ecosystems are widely recognized to be a major factor in determining the quality of groundwater and steamwater. However, to a certain degree, the vegetation will also affect the quantity of water delivered to groundwater and streams. In this study, the differences in composition of soil solution and water-use between arable, grassland and heathland sandy soils were investigated over 2-4 years, with particular reference to the changes occurring as arable soil is set aside as low productive grassland. The arable soil had consistently higher amounts of nitrate, phosphate, potassium and calcium in soil solution, and even though the arable soil was planted with winter barley or winter rye, nitrate concentrations at a depth of 90 cm during winter, reached levels above 2 mM. When arable soil was planted as `set-aside` grassland, the soil solution almost immediately converged to the level of heathland sites with regard to nitrate. Notably, the grassland sites were lower in chloride, sodium and in one region also phosphate concentrations, than the corresponding heathland sites, presumably owing to the accumulation of biomass and litter. In order to simulate the water content in the rootzones of the heathland and grassland soils, it was necessary to decrease the vegetation-specific potential evapotranspiration to 40-60% of that required to simulate the water content of the arable plot. In conclusion, the amount of inorganic constituents in the soil solution from low yielding grassland soils was comparable with that from heathland, while the evapotranspiration from the grassland soil was considerably lower than that on an adjacent arable soil. Thus, by choice of vegetation and management strategy, it is possible to gain some control of the quantity as well as the quality of water delivered from set-aside soil." |
