One major misconception about growing a crop is that once the seed is planted and the crop is up, not much more work is required until harvest. In reality, as soon as growers catch their breath after a rigorous planting season, they must continue making critical management decisions to ensure a good harvest. One important decision is how to manage the sidedress application of nitrogen (N) fertilizer. In this blog, we will explore the benefits of sidedress fertilizer application and how to optimize it for maximum corn yield.
Getting the Most Out of Your Sidedress Program, May 20-22
Along with the increased cost of commercial fertilizers, the adoption of the 4R approach to fertilizer efficiency has changed the way many producers apply nutrients—especially N—to a growing corn crop. In particular, the “right” timing is critical for optimal N uptake. A developing corn plant needs the majority of its N later in the growing season. Specifically, rapid uptake and utilization of N is essential for maximum grain yield from growth stage V8 through VT/R1. Any limitations on plant available N at this point can significantly reduce the crop’s final yield.
Sidedressing N by the V6 growth stage is a common practice, employed to supply the needs of the crop when the N demand is highest. The use of nitrogen inhibitor/stabilizer technology can protect the efficacy of the applied fertilizer, but lacks the ability to convert nutrients into plant-available forms or facilitate uptake by the roots. This is where Accomplish LM, a biochemical fertilizer catalyst specifically formulated to increase nutrient availability and improve plant uptake, comes in.
When Accomplish LM is combined with a sidedress application of fertilizer, increased N availability and facilitation of N uptake results in increased corn yield. Field trials around the country from 2008 through 2012 continually show the increased efficiency of the sidedress applications when combined with the biochemical fertilizer catalyst technology in Accomplish LM.
Results from trials in Sargeant, MN in 2008 and Blissfield, MI in 2010 show a larger, more efficient root system capable of extracting more nutrients from the soil when Accomplish LM is added to a sidedress program. More nutrient uptake correlates to increased grain yield.
