Experimental addition of nitrogen to a whole forest ecosystem at Gardsjon, Sweden (NITREX): Nitrate leaching during 26 years of treatment
Original language description
Chronic high deposition of nitrogen (N) to forest ecosystems can lead to increased leaching of inorganic Nto surface waters, enhancing acidification and eutrophication. For 26 years nitrogen has been added asammonium nitrate (NH4NO3) at 40kgN ha 1 yr 1 to a whole forested catchment ecosystem at Gårdsj€on,Sweden, to experimentally simulate the transition from a N-limited to N-rich state. Over the first 10 yearsof treatment there was an increasing amount of nitrate (NO3 ) and to a lesser extent ammonium (NH4þ)lost in runoff, but then N leaching stabilised, and for the subsequent 16 years the fraction of N added lostin runoff remained at 9percent. NO3 concentrations in runoff were low in the summer during the first years oftreatment, but now are high throughout the year. High frequency sampling showed that peaks in NO3 concentrations generally occurred with high discharge, and were enhanced if high discharge coincidedwith occasions of N addition. Approximately 50percent of the added N has gone to the soil. The added N isequivalent to 140 years of ambient N deposition. At current ambient levels of N deposition there thusappears to be no immediate risk of N saturation at this coniferous forest ecosystem, and by inference toother such N-limited forests in Scandinavia.
