OVERSEER®

For on-farm management and decision support

OVERSEER® is an agricultural management tool which assists farmers and their advisers to examine nutrient use and movements within a farm to optimize production and environmental outcomes.
The computer model calculates and estimates the nutrient flows in a productive farming system and identifies risk for environmental impacts through nutrient loss, including run off and leaching, and greenhouse gas emissions.

Why produce nutrient budgets?

OVERSEER® Nutrient budgets is an agricultural management tool that assists in examining nutrient use and movements within a farm to optimise production and environmental outcomes.

The objective of the development program is to maintain and continue development of a New Zealand wide strategic farm-specific model that is ‘fair and equitable’ by

  • Capturing nutrient pathways and transfers within the farm system.
  • Modelling processes where paths change using robust science processes.
  • Using data that the farmer knows, or is readily available, or suitable defaults are available. The methods of capturing pathways and modelling processes must be commensurate with this data requirement.
  • Maintaining consistency between farm systems by modelling all systems in an integrated model to the same scale.
  • Maintaining focus on mitigation options.

OVERSEER® Nutrient budgets calculates and estimates the nutrient flows in a productive farming system and can be used to identify potential risks of environmental impacts through the calculation of nutrient loss such as run-off and leaching, and greenhouse gas emissions.

It is currently used to develop on-farm nutrient budgets, contributes to whole-of-farm nutrient management plans and, through the use of additional proprietary software, the development of farm specific fertiliser recommendations. The model also provides greenhouse gas emissions, including an LCA-type analysis, to the farm gate.

OVERSEER® Nutrient budgets is a valuable tool for a range of users, in particular farmers and their advisers. It also has a potential role informing policy that includes nutrient management in conjunction with other tools, and in the implementation of policy.

OVERSEER® has been developed on the premise that the model is freely available to all and that it benefits New Zealand farmers.

For this reason, OVERSEER® has not been sold for profit (either alone or in conjunction with other farming software products) by the Owners or by third parties.
