Across Iowa, the forecasted average day/night temperatures are between 30 to 40 degrees F in the coming ten days, so the time is right to cool any grain that went into the bin at higher temperatures. Good harvest conditions and warm weather early this fall mean that there is on-farm grain that...

With rising fertilizer prices, and concerns about possible shortages, it pays to time our applications of anhydrous ammonia and manure well. When the value is high, the focus on management is even more important.

I have yet another weird insect situation to add to what feels like an already comprehensive list of issues for 2021. Last week, a farmer in central Iowa brought a grain sample into an ISU county extension office that was full of small, black beetles. These beetles had survived through the...

Anytime after R3 (milk stage) has traditionally been a great time to do yield checks in corn. After R3, kernel abortion is less likely and plant stress will result in reduced kernel size or fill rather than kernel loss. In addition to performing a yield check, walking late reproductive corn...
