We used to use urea for this very purpose ahead of no till beans, even ploted some of the yields. A complete waste of money both for the bean and 2nd year corn and when accounting inputs for crop year 3-4. the subject is AMS, not Urea there is NO comparison in the Two products. even the Nutrient content is completely different. one would have to be willing to throw 100. $$$ bills away to spread Urea in the fall. with No Sulfate |
