The purpose of this study is to evaluate various starter additive products, applied in-furrow, and their effects on yield and profitability.

2017 Iowa Corn Starter Additive Study - In-Furrow

Data shows that the utilization of a starter fertilizer has produced good results as it provides another application of fertilizer in addition to pre-plant and sidedress. With the addition of an additive in a starter fertilizer program, we have seen some strong results on certain hybrids. XL® 5828AMX™*brand benefited from using an additive, while BECK 6076SXbrand had a relatively large return on investment by just adding a simple additive with an in-furrow fertilizer. This may have been caused by the biologicals in these products increasing the availability of phosphorous that was tied up in the soil.
