This model change features significant enhancements to the modelling of methane (CH₄) emissions from effluent management systems and nitrous oxide (N₂O) emissions.

The new modelling includes incorporating the interaction between animal type and the slope of pasture blocks, an important change for those farming on hill country.

These improvements are designed to enhance the accuracy and reliability of our greenhouse gas (GHG) emission estimates from agricultural activities. The updates are informed by recent advancements in scientific understanding and methodologies, particularly the Agricultural Inventory Model (AIM) approach.

As part of our OverseerFM service, all farm analyses were updated to version 6.5.5 where the farm account had a current paid subscription. All publications were also updated, as were OverseerSci and OverseerEd software services.
