Recovery and Damage Assessment of Hail Damaged Corn in June and July

Recently, severe storms marched across the region bringing along hail that damaged corn in localized areas. After the initial shock of viewing a severely damaged corn field has diminished, the stages of determining the extent of the damage begin.  Agronomic ALERT- Recovery and Damage Assessment of Hail Damaged Corn in June and July

Greensnap and Lodging Issues in Corn

Greensnap mainly occurs in the Western to Central Corn Belt where high winds are more prevalent.  Rapidly growing corn in the late vegetative stages to tasseling is most vulnerable to greensnap.  Rainstorms, with high winds, impact the likelihood of greensnap as well as root lodging.

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…


Iron Deficiency Chlorosis in Soybean

Inquiries occasionally occur about symptoms associated with Iron (Fe) deficiency in soybeans. This article discusses causes, symptoms, and a few management practices if the problem is severe.


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…


Cold Saturated Soil Effects on Corn Germination and Emergence

Corn planted this season could be exposed to cold temperatures and saturated soils. Soil that is saturated and cold can have a negative impact on corn germination and emergence. In addition, cold, saturated soils can cause other problems including surface soil crusting, compacted soils, and seedling diseases. If all of these factors occur, extensive emergence…
