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.
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).
