There’s never a bad time to think about nitrogen applications for next year’s corn crop. The recurring question is when is the right time for your customers to apply? Consider these factors relative to the debate about applying in spring versus fall:
Farmer and former Maryland Secretary of Agriculture Roger Richardson and his family have farmed on Maryland’s Eastern Shore since 1767. They remain steadfast about ensuring the land stays healthy and productive for the next 250 years.
Nitrogen remains the staple nutrient required to maximize corn yields. Other nutrients, however, including phosphorus (P) and potassium (K), also are important.
Dean Sponheim has worked diligently to enhance the quality of the soil of his Iowa farm ever since he began farming in 1979.
Farmers understand that the soil is their most important investment, and operating a profitable farm starts with enhancing soil health.
Spring rain can dramatically increase nitrogen loss through leaching by pushing nitrogen lower into the soil profile.
Do you want Mother Nature to dictate your season, or do you want to keep nitrogen available to corn plants regardless of weather?
Early spring rains can reduce nitrogen availability during key times of early plant growth by converting it to a form subject to loss from leaching and denitrification. Regardless of soil type, up to 70 percent of applied nitrogen is lost below ground through leaching or denitrification, says Eric Scherder, Ph.D., field scientist, Dow AgroSciences.
