Picture of the week: Frost damaged soybeans
These soybeans have suffered frost damage last weekend in Michigan. Soybean yields can decline if frost comes too early, when soybeans are not fully matured. From the looks of this picture, these beans might have some yield loss because they still have some green color. North Dakota State University has an explanation of frost damage in soybeans:
Soybean tops are easily damaged by frost in the 30 F to 32 F range. Temperatures under 30 F for any extended period of time can completely kill soybean plants (stems and leaves). Generally speaking, the soybean fields planted to narrow row spacing (6-7 inches to 15 inches), may have slightly more tolerance to light frosts than soybeans planted in wider rows (30-36 inches). Also soybean plant populations that have thin stands are more affected and injured by frost.
