Late planted soybeans and grain sorghum have taken two successive weekend shots of cold weather, including heavy, killing frosts in many areas of the Upper Southeast.

The result is predictable, ultra-late planted grain yield is almost certain to be well below average for the region.

The problems began with heavy rainfall and long periods of cool, cloudy and damp weather, dating back to May. The rainfall never quit from early May until August and then plants with very shallow root systems — from all the rain — often became drought stressed as rainy weather turned to long stretches of dry weather.

The combination of weather factors in much of the Carolinas and the southeastern areas of Virginia will likely take a heavy toll on all crops, but especially vulnerable are soybeans and grain sorghum planted in July, and in some extreme cases in August.

Growers who planted a month to six weeks behind schedule because of wet ground at normal planting time for double-crop beans and sorghum knew they were rolling the dice. Hoping for a late frost and ideal harvest time conditions, they got dry conditions and a first frost that arrived just about average in most parts of the Upper Southeast.
