Scientific models in GrazPlan applications

Overview of the GrazPlan models

The GrazPlan suite of Decision Support tools are software applications designed to work on desktop and laptop computers. They work on Microsoft Windows machines. Some of the applications also work on Mac OSX and Linux.

MetAccess makes it easy to examine the historical climate and summarise the probabilities and long term weather.

GrazFeed is principally a computer version of the Australian Ruminant Feeding Standards and is targeted at producers and advisors.

GrassGro is designed to analyse management of sheep and beef grazing systems. It is targeted at skilled producers and advisors.

AusFarm is a multi-enterprise modelling tool that is primarily designed for researchers to model mixed farming systems.
