Sidedressing Corn

Corn planting progress this spring has been favorable. However, unsuitable field conditions last fall allowed for little, if any, fertilizer application. As a result, much of the nitrogen (N) fertilizer was applied pre-planting or will be sidedressed this spring. Sidedressing provides the crop with N closer to when it is needed. Growers should be aware…

Goss’s Wilt of Corn

Since its identification in Nebraska in 1969, Goss’s wilt has spread through Colorado and Kansas in the Western Corn Belt, and now occurs in several Midwestern states including Illinois, Indiana, Iowa, Minnesota, South Dakota, Wisconsin, and Wyoming.  Over the past few years, there has been an increase ¡n the incidence and severity of Goss’s wilt…

White Corn Seedlings

Corn seedlings can turn white for several reasons including herbicide injury, genetics, stress which can inhibit chlorophyll production, and low temperature sunscald. The two predominant sources of white corn this year have been stress inhibiting chlorophyll accumulation or low temperature sunscald. It is always important to ask several questions to diagnose the likely cause of…

Possible Causes of Nutrient Deficiency Symptoms in Corn

Several fields are showing what is believed to be nutrient deficiency. Several causes including weather, soil conditions, and nutrient availability may contribute to this symptom. Questions regarding whether the deficiency is due to processes within the plant, problems with root uptake, or an actual soil deficiency should be answered before making additional fertilizer applications this…

Maximizing Soybean Yield Potential

Achieving maximum soybean yield potential will likely depend on increases in stress tolerance, efficient use of all plant growth resources, and increased biomass production. A variety of agronomic practices have shown benefit to increasing soybean yield potential. Selecting what works best on your farm requires careful consideration and implementation.  Agronomic Spotlight – Maximizing Soybean Yield…

Soybean Seedling Diseases

Wet, poorly drained soils and air temperatures below 68° F can be typical during spring planting and crop emergence.  These characteristics favor the development of fungal pathogens that cause soybean seedling diseases. Germination and plant growth can also be reduced. It is important to take steps that may help prevent soybean seedling diseases and scout…

Planting a Range of Soybean Maturities

Stress can lower yield potential in soybeans, especially if the stress occurs during specific growth stages.  Planting a range of soybean maturities, that are adapted to your geography, can help reduce the risk of potential yield loss by spreading out flowering, seed fill, and physiological maturity.  Staggering soybean maturities can also maximize yield potential by…
