A guarantee is settled against a target, not against last year's number. Untreated control fields show what the season did on its own; that adjustment sets what the treated ground owed. Bushels above the target are what the product earned.
1 · Which guarantee?
2 · Crop & Prices
Crop
Crop price is $ per bushel. Treatment price and fertility savings are $ per acre.
3 · Control Fields
Untreated ground, averaged. This is what backs the season out of the result — without it there is no target.
4 · Treated Fields
Treated ground, averaged. Both figures come from the production history document.
