Overseer Review

The independent panel of experts set up to review the nutrient management planning tool OVERSEER®, found that OVERSEER® is currently the best tool available for estimating long term, average nitrate leaching losses from the root zone across the diversity and complexity of farming systems in New Zealand, but that further work on the cropping model is needed to enhance confidence in OVERSEER® estimates of nitrate leaching from arable farms.

Panel members were: Dr Mike Dunbier, Dunbier and Associates Ltd (Chair); Dr Hamish Brown, Plant and Food Research; Dr Doug Edmeades, agKnowledge; Dr Reece Hill, Waikato Regional Council; Dr Alister Metherell, Ravensdown Fertiliser Co-operative Ltd; Dr Clive Rahn, PlantNutrition Consulting, UK; Dr Peter Thorburn, CSIRO; Dr Roger Williams, Foundation for Arable Research.
