Cold soils can lead to chilling injury for newly planted corn and soybean
Warm soil temperatures for the last couple of weeks in Kansas means that corn planting is well underway. However, temperatures for the week of April 23 plummeted below freezing with durations of several hours in many locations across Kansas, particularly the last weekend.

Because of this, soybeans can respond to starter fertilizer applications on low-testing soils, particularly phosphorus. This article discusses when starter fertilizer is most appropriate for soybean production.
