I know it has been talked about before but need opinions on following my field cultivator/anhydrous applicator with my air seeder planting winter wheat. Is there a certain number of days I should wait for the NH3 to "incorporate"? The rains just won't stop and am getting farther behind every time. Still have about a week before I normally start planting but got 2.5 inches rain over the weekend after 14 inches in the last three weeks. I can punt on the NH3 but it is much cheaper than Urea or 28%, cheap grain prices have me looking for anyway to save a few bucks.
