Whether due to planting delays, a cooler growing season, or an unexpectedly early frost, stress factors sometimes result in crops that do not meet standard test weight requirements. So how does reduced test weight affect the feeding value of corn and cattle performance?
Corn ear rots are one of the last diseases to scout for in the corn growing season, and sometimes they are ignored or forgotten entirely. Ear rots can cause yield loss in the form of grain quality at harvest, but also cause losses during storage.

With many flooded and saturated fields in South Dakota this fall, harvesting silage before corn dries past desired moisture levels or frost occurs may be a challenge for some producers.
The chances of a wet October increased with the latest climate outlook update, released on September 30, 2019. In the first few days of the month, rain or snow has scattered across much of the state. There hasn’t been a heavy rain or snow event this month. The outlook shows odds leaning towards much of the same pattern in the weeks ahead.
Corn marketed at the standard moisture content of 15.5% and 56 pounds per bushel typically contains 47.3 pounds of dry matter and 8.7 pounds of water. At harvest, a producer has to decide whether to sell (or even store) his corn at ‘as is’ moisture content or mechanically dry it before taking it to the buyer.
Several corn fields are beginning to show stalk rot and top dieback symptoms. Stalk rots cause the entire plant to die prematurely, which can lead to plants lodging under windy conditions making harvesting problematic.
