Phosphorus (P) fertilizer is often added to cropping systems to increase yield, but growers should not overlook the importance of micronutrients like Zinc (Zn). Understanding some of the nutrient interactions that affect nutrient availability can help with management decisions like fertilizer source.
Evaluate the yield response of corn to potassium (K) using MOP and Aspire® in a spring broadcast application.
Evaluate the yield response of corn to Aspire®, MOP and MOP + Granular B blend in fall vs. spring applications.
Regardless of fall or spring application, a banded application of MicroEssentials® SZ® is a superior technology for improving nutrient use efficiency.
Quantify the effect of a comprehensive fertility program including MicroEssentials® SZ® (12-40-0-10S-1Zn) + Aspire® (0-0-58-0.5B) compared to a conventional fertility program of MAP (11-52-0) + MOP (0-0-60) or MAP Only in a four-year cropping system.
The growing season of 2014 has the potential to yield a record harvest in many areas of the country. With good weather conditions, high soil fertility and a combination of high-yielding varieties, crops look strong and healthy. But there’s more being removed from the fields than just a crop harvest — record yields mean record nutrient removal from the soil.
A common practice in the U.S. Midwest is to combine the quantities of phosphorus (P) and potassium (K) recommended for both corn and soybean crops into a single application. This biennial application of fertilizer is usually applied after soybean harvest. In a corn/soybean rotation, this results in a “direct” application to corn and a “residual” application to soybeans. Less common, although also studied by scientists, has been a biennial application applied after corn, resulting in a direct application to soybeans and a residual application to corn.
Whether you are growing wheat, canola or corn, you can set the stage for a healthy growing season and maximum yield with early-season treatments and starter fertilizer.

A recent study from DuPont Pioneer outlined the continuous-corn yield penalty, and the causes for that penalty. Over a six-year period, the study found that continuous corn yields, on average, 25 bushels per acre fewer than corn that follows soybeans.
Corn growers need balanced crop nutrition to maximize a corn crop's yield potential and get the most out of their fertilizer investment. In practice, this requires making all of the required nutrients available to the corn crop at the right time.
