Up to 250 hectares, you pay a fixed amount; from 250 hectares we use a graduated scale per hectare. The reference date for determining the number of hectares in AgroVision Crops is 15 May. The invoices of quarter 1 and 2 are based on the hectares (Cultures) on 15 May of the previous crop year and the invoices of quarter 3 and 4 are based on the hectares in use on 15 May of the current crop year.
