15-30-15 is our most common “pop-up” for members of the grass family, including corn, grains, and sorghum.   Although many growers have used it successfully as a row place product with soybeans, there is the possibility of some germination problems due to the sulfur that is part of the nutrient package.   It may be used as either a stand-alone row place product, or due to its very high trace mineral content, can also be mixed with common liquid fertilizers such as 10-34-0 to enrich the overall nutrient package.

It is designed to be applied in the row, but has also shown to be of strong benefit applied through drip irrigation systems.
