This feature is available to "Professional" users.
This calculator is provided by Field Track to aid in finding out the potential of cropping plans based on crop types, area, yields, price/tonne, variable costs and fixed costs.
Give each entry a season and crop type and fill in the potential figures. You can thus soon build up a projection of crop types over serveral seasons to give you a handy forecast of possible cropping plans.
Right-clicking on the grid provides useful features.
