OVERSEER® Nutrient Budgets (Overseer) was engineered as a decision support tool to illustrate nutrient flows around farm systems. It also includes maintenance fertiliser nutrient recommendations and is integrated with Fertiliser Company systems to provide fertiliser recommendations.
Its strength is that the user is able to represent a farm system with a manageable amount of input data; the model then estimates nutrient flows around that farm system. Version 6, to be released in 2012 marks a step change in the model development.
