Please note: OVERSEER Nutrient Budgets will be phased out by the middle of 2019, at which time you will no longer be able to use this software. We have developed new, more user-friendly OverseerFM software that is available at – you can find out more information at You can upload XML farm files from this legacy software into an OverseerFM farm account. The files need to be created in (or have been updated to) version 6.2.3 or version 6.3.0.

Please note: OverseerFM is free to use until January 2019 at which time a subscription charge will be applied per farm. Those using this version of OVERSEER Nutrient Budgets for research and science projects need to continue with this legacy software until we have the new OverseerScience product available later this year.
