Sponsored: A holistic Approach to Nutrient Management

In addition to nitrogen, phosphorus and potassium needed for corn development

Nitrogen remains the staple nutrient required to maximize corn yields. Other nutrients, however, including phosphorus (P) and potassium (K), also are important.

Realizing maximum yield in the fall begins with a holistic approach to nutrient management. This includes making sure phospohorus and potassium levels are adequate to support growth throughout the entire season and protecting nitrogen applications with a nitrogen stabilizer.

“Making sure that adequate levels of P and K are available for the crop throughout the growing season is critical for achieving optimum crop growth and development,” says Eric Scherder, Ph.D., field scientist, Dow AgroSciences. “Realizing maximum yield in the fall begins with a holistic approach to nutrient management. This includes making sure P and K levels are adequate to support growth throughout the entire season.”

Soil fertility levels for P and K are affected by their inherent availability in the soil, past crop removal amounts and soil pH. Prior to the growing season, existing P and K fertilizer programs should be evaluated. If soil tests indicate adequate P and K levels, farmers should continue to apply fertilizer to compensate crop removal levels. If soil tests are below minimum levels, additional P and K fertilizer should be considered.

To round out the holistic approach to nutrient management, farmers also should make sure that applied nitrogen is still available in the root zone for plant uptake, especially if heavy rains occurred after nitrogen was applied, as was the case in many areas of the Corn Belt early this spring.

“If additional nitrogen is required during the growing season, it is important for farmers to consider using a nitrogen stabilizer like Instinct with sidedress applications to ensure maximum uptake and to minimize potential leaching if midseason rains occur,” Scherder says.
