Dryness impacting in-season fertility plans
June 21, 2021 By Mark Dorenkamp Filed Under: Crops, Minnesota, News
Widespread dryness is limiting in-season fertilizer applications.
University of Minnesota Extension soil fertility specialist Daniel Kaiser says some farmers planning to side-dress are unsure of when and what to apply.
“Mainly because there’s some risk, particularly with dry conditions, for volatility of ammonia off of urea and urea-based fertilizers. Certainly dry urea is going to be the worst in terms of overall risk.”
He tells Brownfield because UAN is banded with 50 percent urea, there’s a lower chance for loss.
“Really the best option if you can’t play the game of trying to apply right before a rain would be looking at putting on some product like an AGROTAIN would really be the best option (because) it would limit volatility.”
Kaiser suspects potassium deficiency will also become a bigger problem in the next month in areas that remain dry.
