S.E. Iowa | We have always waited 3 days which includes using a field cultivator before planting , If you having it custom applied make them knife it in and put it deep, you want the NH3 in the ground where the roots will be when the NH3 is most needed by the plant. The custom people like to use disc not because it gets the Nh3 to the right depth but because they can cover more acres quicker. | |
