The purpose of this study is to compare the use of different sugar products, applied at the V4 growth stage, and their impact on yield and profitability.

Many of the products tested in our sugar study contain nutrients and organic acid. We targeted the V4 growth stage for these sugar applications as it’s at this point that corn plants are relatively small and have little leaf surface area in comparison to the bare soil surface. Because of this, we rationalized that a majority of the applied sugar ended up on the soil surface, which may have had a positive effect on the naturally occurring soil bacteria. Because early-season temperatures and rainfall were above average, these applications may have provided a boost to already active soil microbial populations, resulting in greater nutrient availability for the corn crop during the remainder of the growing season.
