This tool by the Rodale Institute allows you to create a side-by-side comparison of conventional and organic management on your farm. Just select the crop you’d like to compare and the acreage. They will fill in the rest with historical data derived from USDA and projections from their own research at Rodale Institute. The Crop Conversion Calculator will then show you a line-by-line comparison of the two systems so you can see just how they would stack up on your farm.
