The purpose of the report is to provide insights into the perceptions of Overseer, what influences these perceptions and why? This was achieved through the completion of 35 interviews. To enable the author to analyse a range of views, interview groups included dairy and drystock farmers from the Waikato, farmers facing nitrogen regulations, agricultural consultants and regional council staff.
The main findings of the survey were:
- Age and past exposure to the Overseer model are key influencers on farmer’s current perceptions.
- The users of Overseer are key influencers of farmer perceptions, understanding and acceptance of the Overseer model.
- The accuracy of Overseer model output is viewed to be influenced by a number of factors, including accuracy of data supplied, consistency of file creation and the limitations of Overseer to model complex farm systems.
- There is a real concern across all sectors of the future use of Overseer in regulation, at its current perceived level of accuracy and credibility.
- The Overseer model is effective at completing the tasks that it was initially designed for, that being to aid on-farm nutrient management decision making.
