| Description: | Since urea is becoming a primary source of N-fertilizer in dry-granular blends and in liquid formulations, there is reason to be concerned whether such urea-containing fertilizers should be used for grain-drill application with the seed. We found germination damage and root pruning increased progressively 27 days after seeding as the rate of urea-N applied with the seed increased. For every 10 lbs/acre of actual N applied with the seed, spring wheat stands decreased about 13 percent and grain yields decreased 3.1 bu/acre. To prevent such losses, liquid or dry-granular N-fertilizer materials that contain urea-N should be broadcasted and incorporated before seeding or banded to the side and below the seed. |
