A new way to measure denitrification in groundwater has been proved, and could make analysing groundwater’s denitrification capacity more accessible for regional councils and farmers. The new method for measuring excess nitrogen could be used to locate and characterise groundwater denitrification sites, so spatial variability of sites and rates can be mapped. Identifying the location and efficiency of groundwater denitrification sites can result in more effective nutrient loss regulations, more strategic nitrogen loss mitigation measures and improved land management
