Walvoord et al. (1) reported a large nitrate pool located deep (1 m) beneath desert soils.Two aspects of this work were particularly surprising: the large pool size, estimated to beup to 104 kilograms of nitrogen per hectare, as nitrate (kg N ha1); and the shape of thenitrate profiles, which resembled the conservative solute-accumulation profiles of Cl morethan typical nutrient depletion profiles.............
