The purpose of this study is to evaluate starter additive products, applied with nitrogen on both sides of the row at planting, and their impact on yield and profitability.

2021 Iowa Corn Starter Additive Study - 2x2x2

When applied at planting, zinc is beneficial to seedling development and nutrient interaction, but it is most successful when placed in the seed trench. Nitrogen stabilizers are most successful when used in situations where leaching or volatilization risks are the highest and usually not in a 2x2x2 placement.
