Corn growers in Minnesota have been trending to applying more urea than anhydrous ammonia for their nitrogen source over the last few years. That’s according to University of Minnesota Extension Educator Brad Carlson who says that’s due to several factors
He says Urea is generally only effective in the spring and not in the fall and that because it’s usually a much safer product than anhydrous, that has led to more usage of it lately.
Carlson says he hasn’t heard or seen any availability issues with Urea but that anyone storing it should be registered and in contact with the State Agriculture Department.
Besides the shift being more toward Urea over Anhydrous during the last five years, the other trend has been more growers building storage facilities on their farms.
