Figure 1. Planting into cold soil (below 50°F) when cold conditions are expected for the next 48 hours can lead to germination problems and seedlings not emerging or not emerging well. 1a. Corn seedling that started leafing out below ground and now has twisted leaves which will delay or negate normal plant development.. Figures 1b-c. Unemerged seedlings attempting to leaf out belowground. None of the seedlings shown should be counted as a productive plant.

Cold Soil Temperature and Corn Planting Windows April 12, 2018

With stormy conditions back in the picture, many growers may be concerned about planting corn into cold, wet soils? By checking weather forecasts and soil temperature at planting (in the field and online) and the cold tolerance of seed, growers can identify 48-hour windows of opportunity for planting.
