Abstract

- Short-term increases in soil solution nitrate (NO3-) concentration are often observed after forest harvest, even in N-limited systems. We model NO3- leaching below the rooting zone as a function of site productivity. Using national forest inventories and published estimates of N attenuation in rivers and the riparian zone, we estimate effects of stem-only harvesting on NO3- leaching to groundwater, surface waters and the marine environment. Stem-only harvesting is a minor contributor to NO3- pollution of Swedish waters. Effects in surface waters are rapidly diluted downstream, but can be locally important for shallow well-waters as well as for the total amount of N reaching the sea. Harvesting adds approximately 8 Gg NO3-N to soil waters in Sweden, with local concentrations up to 7 mg NO3-N 1(-1). Of that, similar to 3.3 Gg reaches the marine environment. This is similar to 3% of the overall Swedish N load to the Baltic. (C) 2010 Elsevier Ltd. All rights reserved.
