Overseer upgrade released
3 August 2012
Farmers and growers are being offered an enhanced tool to help them use nutrients efficiently.
The owners of the OVERSEER® Nutrient Budgets software are releasing a major upgrade today.
Overseer is available free of charge through a partnership between the Ministry for Primary Industries, the Fertiliser
Association of New Zealand and AgResearch.
The upgrade to Overseer Version 6 reflects user feedback on previous versions says Mark Shepherd of AgResearch, the
Overseer technical team leader.
“Nutrients are a valuable input, and Overseer is a tool that advisors can use to help farmers and growers get the best
use from them. We are continually striving to make it as useful and relevant as possible. This is a major upgrade.”
The owners have worked closely with fertiliser companies as key users, and also with stakeholder groups including local
and central government.
The new version of Overseer includes many changes to better represent farm systems, adjustments following a review of
underpinning science, and new software.
In addition, it includes two new features: the ability to produce a life-cycle assessment of greenhouse gas emissions
and a new dairy goat model.
Philip Mladenov of the Fertiliser Association says the fertiliser industry is pleased to be a partner in the Overseer
development programme. “Overseer Version 6 represents a major advance over the previous version and will help our
nutrient management advisors provide the best advice possible to farmers and growers on using nutrients sustainably.”
