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

2017 Minnesota AgRevival Corn Starter Additive Study - In-Furrow

Each of these starter additive products contains microbes that appear to have promoted nutrient availability and helped feed the corn plants. The addition of microbes, even in small quantities, were likely beneficial as the naturally occurring microbes in these soils would not reach full activity levels until later in the summer when soil temperatures had risen. It also appears that the microbes in the first three products had more affinity for these soils.
