It’s time for another Yield Forecast. A new Yield Forecast came out from the UNL project on July 29. For Iowa, this new forecast is similar to the July 15th forecast with the exception of northwest Iowa. Rains in northwest Iowa have increased yield potentials to 94% likelihood of being near or above the long-term average compared to 85% in the July 15th forecast.
The range of yield potentials forecast is still large due to there being most of the grain fill period yet to come. It should be noted that this forecast does not take into consideration stand establishment issues, hail, flooding, replant situations, disease/insect incidence, or nitrate leaching.
