The research was divided into two main objectives which comprised firstly of generating herd testing data (using urine sensor technology) on four case-study dairy farms (located in Waikato and South Auckland, New Zealand) over the first two years of the project (Objective 1). The second phase of the project (Objective 2) utilised data generated in Objective 1 for scenario-based modelling using OVERSEER® model (OverseerSci, version 6.5.1) and subsequent research on how this information could be integrated into the model to mitigate farm N leaching loss with future research and challenges identified.
