Information Management to Maximize Your Yields

Optimum Temperatures for Planting

Corn requires a soil temperature of 50° F to germinate and grow, while soybeans require a soil temps above of 54° F. Temperatures below the optimum will cause seeds to sit dormant and become more vulnerable
to diseases, insects, and animal predators.

Planting into cold and/or wet soils can lead to numerous problems. Waiting for appropriate soil temperatures and conditions may help avoid chilling injury, disease, lack of oxygen to the seeds, and restricted plant growth which can all lead to poor emergence.

Although it is important to plant within the acceptable planting window for the region and crop, rushing to plant in cold, wet conditions can lead to yield reducing problems later.
