While the cycling and leaching of nitrogen in the soil profile (root zone) is reasonably well understood, there is limited information available about its transport and transformation in the subsurface environment (below the root zone), particularly in the Manawatu River catchment. To address this, Massey University’s Institute of Agriculture and Environment (IAE) and Horizons Regional Council has established a collaborative research study to monitor and model the transport and transformation of nitrate-nitrogen from farms to river via groundwater in the Manawatu River catchment.11en© The Authors and FLRCnitrogensubsurface environmentConference Contribution - publishedANZSRC::0503 Soil SciencesANZSRC::060204 Freshwater EcologyANZSRC::079902 Fertilisers and Agrochemicals (incl.
