Neglecting the spatial variation in soil nutrient status may result in unused yield potential and in environmental damage.
Site-specific management has been suggested to reduce inappropriate fertiliser application that can adversely affect soil, ground and surface water. Decision criteria for determining variable-rate nitrogen fertiliser applications are however still lacking, partly due to the poorly understood spatial and temporal variation of nitrate concentrations in soils.
