There is no single best way to fertilize corn in Manitoba. The 4 most common N application methods are spring broadcast and incorporated, fall banded, banded at seeding and preplant banded.
In a dry spring like 2019 (similar to 2018), broadcasting and incorporating fertilizer before seeding, risk drying out the seedbed. Many farmers, especially on clay-textured soils prefer not to disturb their seedbed in the spring and so prefer to fall band their N. And although spring preplant banding is a very efficient way to place nutrients for a corn crop, it comes with some particular cautions – thinning and seedling injury.
