“…Spruce had less throughfall than broadleaved species and it is suggested that the percolation in forest ecosystems is largely controlled by canopy throughfall and interception and to a lesser degree by transpiration and soil evaporation. These findings are in accordance with previous studies (Alavi et al, 2001;Ladekarl, 2001;Mossin & Ladekarl, 2004;Christiansen et al, 2006;van der Salm et al, 2006) which found that canopy interception accounted for the major differences in percolation between deciduous and coniferous forests. As future afforestation projects mainly focus on broadleaved forest types it is also relevant to evaluate which deciduous species will yield the highest amount of percolation water and at the same time retain N.…”

“…It was possible to simulate the water balance adequately at Mattrup and Vall based on calibration of simulated input of water to measured values of throughfall and subsequent calibration of simulated soil water content. Chloride flux balances are often used in studies of forest water balances to validate water balance simulations (Ladekarl, 2001;Mossin & Ladekarl, 2004;van der Salm et al, 2006). As chloride is assumed to be a conservative element in the environment the input flux should ideally be equal to the leaching flux, but the response of the leaching flux to chloride input events can be delayed for long periods due to changes in soil water storage and uncertainties of chloride concentration measurements (Wood, 1999;van der Salm et al, 2006).…”

Water and nutrient fluxes for single stands of different tree species have been reported in numerous studies, but comparative studies of nutrient and hydrological budgets of common European deciduous tree species are rare. Annual fluxes of water and inorganic nitrogen (N) were established in a 30-year-old common garden design with stands of common ash (Fraxinus excelsior), European beech (Fagus sylvatica L.), pedunculate oak (Quercus robur), small-leaved lime (Tilia cordata Mill.), sycamore maple (Acer pseudoplatanus) and Norway spruce (Picea abies [L.] Karst.) replicated at two sites in Denmark, Mattrup and Vall during 2 years. Mean annual percolation below the root zone (mm yr À1 AE SE, n 5 4) ranked in the following order: maple (351 AE 38)4lime (284 AE 32), oak (271 AE 25), beech (257 AE 30), ash (307 AE 69) ) spruce (75 AE 24). There were few significant tree species effects on N fluxes. However, the annual mean N throughfall flux (kg N ha À1 yr À1 AE SE, n 5 4) for spruce (28 AE 2) was significantly larger than for maple (12 AE 1), beech (11 AE 1) and oak (9 AE 1) stands but not different from that of lime (15 AE 3). Ash had a low mean annual inorganic N throughfall deposition of 9.1 kg ha À1 , but was only present at Mattrup. Annual mean of inorganic N leaching (kg ha À1 yr À1 AE SE, n 5 4) did not differ significantly between species despite of contrasting tree species mean values; beech (25 AE 9)4oak (16 AE 10), spruce (15 AE 8), lime (14 AE 8) ) maple (1.9 AE 1), ash (2.0 AE 1). The two sites had similar throughfall N fluxes, whereas the annual leaching of N was significantly higher at Mattrup than at Vall. Accordingly, the sites differed in soil properties in relation to rates and dynamics of N cycling. We conclude that tree species affect the N cycle differently but the legacy of land use exerted a dominant control on the N cycle within the short-term perspective (30 years) of these stands.

“…For Ei the shares are 18% for beech and 46% for N. spruce, thus the interception loss in spruce is more than twice of that in beech. A high interception loss in spruce forests was also reported by Alavi et al (2001) and Mossin and Ladekarl (2003). Mossin and Ladekarl also concluded that a high interception loss would lead to low percolation.…”

Two contrasting forest ecosystems located in close proximity to each other were selected for evaluating the importance of tree species and afforestation in relation to the water balance and the quality of the water leaving the forest root zone. Measurements included soil water content and the collection of precipitation, canopy throughfall, stem flow and soil solution on a weekly basis during 15 months (1999)(2000). Soil solutions were extracted using suction probes installed at all major horizons within the upper 120 cm of a Norway spruce (N. spruce) stand (Picea Abies [L.] Karst.) and a European beech stand (Fagus Sylvatica L.) located on the same soil type. Soil solutions were analyzed for the content of all major ions, including nitrate. A water balance model (CoupModel) was used to estimate percolation rates beneath the root zone. Percolation at the beech stand was 292 mm and only 41 mm at the N. spruce stand mainly due to differences in the interception loss. The highest annual leaching of Mg, K, Na, Al, Cl, SO 4 -S was noted in the N. spruce stand while leaching of NO 3 -N was highest in the beech stand, corresponding to 39 kg ha À1 year À1 . By contrast, the annual leaching of NO 3 -N in the N. spruce stand was only 0.5 kg ha À1 year À1 . The larger amount of NO 3 -N was leaving the beech forest soil despite the fact that the N. spruce stand had the highest atmospheric N-deposition. Thus, differences in NO 3 -N leaching between the stands must be related to differences in uptake and accumulation of N in the vegetation and within the upper 120 cm of the soil. Differences in the water balance and NO 3 -N leaching between beech and N. spruce stands call for further attention to the selection of tree-species on a soil type basis when planning future afforestation projects, particularly when such projects aim to improve the quality of water infiltrating to the groundwater zone. #

“…The K c value used for forest is relatively high. However, on the basis of investigations by Mossin and Ladekarl [2004] and van der Salm et al [2006] evaporation from the intercepted water is responsible for a relatively high potential evapotranspiration from conifer trees in this area.…”

[1] This paper presents a quantitative comparison of plausible climate and land use change impacts on the hydrology of a large-scale agricultural catchment. An integrated, distributed hydrological model was used to simulate changes in the groundwater system and its discharge to rivers and drains for two climate scenarios (2071-2100). Annual groundwater recharge increased significantly (especially the B2 scenario), giving higher groundwater heads and stream discharges and amplifying the seasonal dynamics significantly. Owing to drier summers, irrigation volumes increased by up to 90% compared to current values. Changing the land use from grass to forest had a minor effect on groundwater recharge, whereas CO 2 effects on transpiration resulted in a relatively large increase in recharge. This study has shown that climate change has the most substantial effect on the hydrology in this catchment, whereas other factors such as irrigation, CO 2 effects on transpiration, and land use changes affect the water balance to a lesser extent.
