This year continues the chain of growing seasons with extremes and rapid changes beyond our long-term experiences. This made for periods of both stress and favorable crop growth despite the planting dates. Frost, potentially killing in the northern half of Iowa, is expected between October 11-13. USDA data indicate a wide range of maturity due to planting date, but the periods of hot weather scattered through September and early October may have reduced the potential for very high moisture corn and soybean. Variability will be the key issue to manage in 2019 corn and soybeans.

Corn Quality Issues in 2008 - Moisture and Test Weight

October 24, 2008

Weather this fall has benefited the corn crop by allowing late planted corn to mature. Much of the state recently experienced its first killing frost. The USDA October yield estimate of 172 bushels per acre in Iowa surprised many. If this is the final yield, 2008 will produce the third highest yield recorded, behind the 173 bushels per acre of 2005 and 181 bushels per acre in 2004.
