On-farm decision support
OverseerFM is a powerful decision support tool that helps farmers and growers to improve their farm's environmental and economic sustainability. The FM stands for Farm Modelling - and sits the Farm at the centre of the software.

The software uses science modelling to create a picture of your farm’s nutrient performance - including how much and where you are losing nutrients into the environment through leaching and greenhouse gas emissions.

By using OverseerFM, you can understand:

  • what management areas on your farm are likely to be leaching more and how that relates to your total farm losses

  • what nutrients are required to maintain soil fertility based on existing production levels

  • the likely greenhouse gas emissions being generated on your farm and the carbon footprint for your products

  • the likely impacts on leaching and greenhouse gas emissions of changes in farm management practices, introduction of mitigations and changes in farm enterprises or systems.

  • what area is recommended for effluent application (for farms with effluent systems).

The real value from Overseer comes when it is used to support decisions around management and system changes. It allows farmers and their advisers to test the potential impacts of different approaches both as part of increasing nutrient use efficiency on farm or when assessing significant changes to land use.

Every farm is different and the right solution will be different for each farm too. When used with other farm support tools and knowledge, Overseer takes the guess work out of making changes.

Overseer analyses most farm systems including dairy, sheep, beef, deer, goats, pigs, kiwifruit, apples, grapes, avocados, peaches and seed, grain and some vegetable crops.

Why move to OverseerFM?

saves time by making it easier to enter and share data - to avoid unnecessary duplication
supports more consistent and more accurate analyses through everyone working from the same base farm information and through separating different types of analyses
creates greater engagement with farmers through presenting results in more meaningful ways (like showing trends over time)
offers greater data security and control through farmer-based permissions and central storage

How it works 

OverseerFM is specifically designed for farmers and rural professionals to support nutrient management decisions and enable environmental compliance.
Anyone can register for OverseerFM, but only those who have permission can access Farm Accounts to undertake farm modelling. 
Scientists and researchers need to continue to use the legacy OVERSEER Nutrient Budgets software until we have our new OverseerScience software available in 2019.


Slide background

Using OverseerFM

To register, go to fm.overseer.org.nz, and you'll find user guides and information sheets once you register.  
For those of you with existing Overseer farm files - these can be uploaded into a Farm Account in OverseerFM, but they need to be in v.6.2.3 or v. 6.3.0. 
Please note, use of OverseerFM is subject to new Terms and Privacy Policy, which you will be asked to read and accept when you register.
Users can continue to use the legacy OVERSEER Nutrient Budgets for a period, but the application will be discontinued in the first half of 2019.           



OverseerFM is currently available for free for six months, but we will be charging an annual subscription per farm account from February 2019.

Using OverseerFM for compliance

The centralised farm account in OverseerFM replaces the XML files in the legacy product. 

Like submitting tax information from online accounting software OverseerFM allows users to provide information to councils as required - this is done through using the "publication" button and publishing a specific analysis to the chosen Council (or other organisation).

We have been working closely with Regional Councils in the development of the new software and to allow them to consider changes they may need to make in their processes.

If you would like further information, please contact your Regional Council directly.
