Understanding Crop ROI
Return on investment for arable crops measures how much profit you generate relative to total growing costs. A positive ROI means the crop is profitable after all variable and overhead costs. For home-use crops such as wholecrop silage or home-grown cereals, the savings versus buying in can be equally important as the sale value.
