Abstract
Demands for forest biomass production for energy, construction and carbon storage purposes are increasing, and therefore measures to increase tree growth are required. One potential measure is nitrogen (N) fertilization, as N is usually the most growth-limiting nutrient in boreal forests and partly due to decreasing atmospheric N deposition in northern Europe in recent decades. However, N fertilization can have adverse effects, such as soil acidification and N leaching, particularly nitrate leaching via streamwater flow. To mitigate the acidification risk, dolomite (CaMg(CO3)2) is added to N fertilizer boron (B) as increased tree growth hamper tree uptake of this essential micronutrient. This study examined the effects of forest fertilization on streamwater chemistry in the 45 ha Swedish catchment Risfallet (RF), around 80% of which was treated with fertilizer. That was rather exceptional, as most previous catchments studied have had
