The early spring and accompanying early planting, together with last fall’s dry conditions in many areas, may present unique management challenges to growers planning nitrogen (N) applications. These conditions can mean nitrogen loss and impact corn yields.
“For a successful corn crop, it’s important to factor in the uncertainties of weather and the dynamic nature of the nitrogen cycle,” said John Shanahan, Pioneer agronomy research manager. “After all, a sound corn nitrogen plan sets the stage for a high-yielding crop.” Last fall’s dry soil conditions led to anhydrous ammonia applications on many of the acres in the Corn Belt. In the spring, excessive rain can threaten these soil nitrogen reserves and hinder resupply by ground equipment. Excessively dry conditions in the spring also can prevent applied nitrogen from moving from the point of application to the root zone of plants. Temperature and moisture conditions also can impact the amount of nitrogen mineralized from the organic matter fraction of soils.… Continue readingRead More »
