The Right Soil Type

Different soil textures (e.g., the percentage of sand-, silt- and clay-sized particles in the soil) can dramatically affect the emergence and growth of a corn plant, as well as its ability to recover from heat and moisture stress during different growth stages of the corn life cycle. Work with your WinField representative, and use Answer Plot® data and the R7® Tool to help select hybrids that include the type of root system morphology (fibrous versus penetrating) that will perform best with the soil texture in each field.

Hybrid Characterization By Soil Type

Answer Plot® data show the importance of selecting the correct hybrid for your soil type based on its characteristics, as this can create a difference in yield potential. In this example, Hybrid A, given the percent of mean, performed consistently in a fine, medium and coarse soil. Yet, there are other products that could have been selected to achieve a higher percent of mean on those soil types. In comparison to other products on fine soils, Hybrid A is actually one of the top-performing hybrids. Hybrid B expresses its greatest yield on medium and fine soil. However, Hybrid C performed more favorably than others when planted in a coarse soil environment.

R7® Tool Soil-Type Map

It’s important to know the predominant soil type of each field to select the best corn hybrids. The R7® Tool lets you view both traditional soil-type maps as well as satellite-derived bare soil images. This field-specific information can help you determine the right hybrid for each field.

Soil Texture Triangle

For optimal performance, hybrids should include the right root systems to match the soil conditions within each field.
