10+ years ago tried strip-tilling in the spring, memory might be little off on the rates, but I believe was shooting for 100 lbs. actual N and was using shank style machine set at 5-6". Waited at least 4 days and started planting, all of the corn germinated and came out of the ground, this I remember because I was nervous about doing this in the spring. Couple weeks after corn emerged, I started spraying the corn and noticed areas of the field where corn didn't look real healthy. Then found some fields that looked terrible so we called seed rep to come take a look. I did not even think about NH3 burn because all of the corn made it out of the ground and looked good earlier. Seed rep started pulling plants and noticed the bad looking plants had roots that were brown, not healthy, and some were trying to grow sideways and not straight down. If my memory serves right, there was no rain after planting. Although the corn was able to emerge, the hot zone where I placed nh3 was burning the roots. The better and darker the soil was, the less harm I noticed to the corn.
No way of knowing how much yield was lost, but I do know it was significant, and the corn was higher in moisture than neighbors when combining. I know I never tried gas in the spring with strip-till after that experience. | |
