英文摘要	The date palm (Phoenix dactylifera), an important agricultural crop in arid and semi-arid areas around the Mediterranean Sea, has high nutritional, cultural, and economic values. Date palm cultivation in Israel is practiced in the arid and hyper-arid Jordan and Arava Valleys and is associated with high water and nitrogen (N) fertilization inputs, with rates of up to similar to 170 m(3) water and similar to 6 kg N per full-grown tree annually, on average. While the palm's water needs and budget have been intensively studied, the fate of applied N has received little attention to date. Understanding this fate is especially important since high fertilization rates of similar to 740 kg N ha(-1) may have deleterious effects on the environment. Specifically, soil emissions of nitrous oxide (N2O) and leaching of nitrate (NO3-) are of major concern, due to their impact on climate change and groundwater contamination. We have measured the effect of four levels of N fertigation (fertilization + irrigation), between 0 and 2.55 kg N tree(-1 )yr(-1), on N2O and NO3- fluxes during an annual growth season in a three-year-old date palm orchard located in Israel's hyper-arid Arava Valley. We used static chambers for soil N2O flux estimations and measured drainage water NO3- concentrations at a 60-cm depth, together with a CF mass-balance-based water budget to estimate the NO3- leaching. We observed trivial soil N2O emissions of up to similar to 0.02% of applied N, while NO3- leaching was estimated to be as high as 36%. Dry areas between the trees, which did not receive any fertilization or irrigation, exhibited even lower N2O emissions than the irrigated areas. Inorganic N, however, accumulated during the dry months in the upper layer of the soil and was later lost at the onset of the winter rains. Our results provide the first-ever estimations of the potential environmental impact of date palm plantations in Israel and the Mediterranean Sea Basin.
