Farmers on the fence about whether their corn crop needs more nitrogen should go ahead and bite the bullet. Thanks to excessive rain and waterlogged soil, corn crops throughout Missouri don't have access to enough nutrients, and a University of Missouri Extension agronomist says that could mean a major loss from unrealized yield.
"I think that rescue nitrogen applications will be profitable on 80 to 90 percent of Missouri cornfields outside of the Bootheel, and many farmers can make a lot of money on it," said Peter Scharf. "Last year we estimated that the whole northeast part of the state was 50 bushels per acre below what it could be, and when you start thinking what you can do for that kind of money, you realize you can do quite a lot."
Scharf estimates that nitrogen deficiencies are even worse than last year, when an estimated 113 million bushels of corn yield weren't realized in Missouri alone due to the lack.
