VRA Rekenmachine
With use of the VRA Calculator, formulas can be created which can be applied on datalayers of the field. The data layer can be converted into a task card of the field which can be easily used by machinery. In this way, a soil scan or yield calculation of the previous season can be used to create a manure application task card.
