Carbon (C), especially carbon dioxide (CO2), is a topic that is constantly being discussed for its role in the environment.
Growers may consider reducing fertilizer rates for various reasons such as lower crop prices, higher input costs, lower than expected yields, or uncertainty of profitable yield responses.
Organic matter (O.M.) plays a significant role in crop production and soil health. Building and maintaining a healthy soil that has more O.M. can aid in providing a stronger foundation for higher crop yields and resiliency to environmental stresses.
Evaluate the corn yield response to MOP (0-0-60) and K-Mag® Premium (0-0-21.5-10.5Mg-21S).
Evaluate soybean yield response to MAP (11-52-0) + MOP (0-0-60) and a combination of MicroEssentials® S10® (12-40-0-10S) + Aspire® (0-0-58-0.5B)
Evaluate soybean yield response to Aspire®, MOP and a MOP + Granular B blend in fall vs. spring applications.

Evaluate onion marketable yield response to MAP (11-52-0), MAP + MOP (0-0-60) and MAP + MOP + K-Mag® Premium (0-0-21.5-10.5Mg-21S).
Sulfur (S) is an essential element for all crops. Sulfur deficiency has become more common due to decreased atmospheric inputs, higher yields, and a shift to high-analysis fertilizers with little or no S. Commonly used S fertilizer sources contain either sulfate-S (SO4-S) or elemental sulfur (ES).
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.
