Our Methodology
Our crop rotation ROI calculator is based on more than 10 million acres, combined with the latest research compiled by Granular Data Scientists. We account for the expected yield penalty for repeat crops (based on your state) as well as the anticipated cost increase for the suggested mitigation strategies. Budget costs are calculated using numbers provided by your local state university, and the crop price is market closing cost (updated daily via Barchart™.)
*Other considerations we took into account:
A second-year corn crop typically requires:
Additional nitrogen inputs estimated at $19/per acre
Pesticide application estimated at $24/acre
Slightly more labor input (for pesticide applications, scouting, and more intensive tillage than conventional corn on soybeans crop) estimated at $4/acre
Continuous crops typically mean a yield reduction of as much as 4% for corn and 10% for soybeans (although the corn on corn reduction can generally be offset by increasing N)
Although not included in the calculation, many fungal infections can survive the winter in soybean residue and thus a second-year soybean crop may require seed treatment or in-season fungicide application
