Since its discovery as a new species in 2019, soybean gall midge continues to be found in new counties across five states in the Midwest. For some farmers, the presence of soybean gall midge had a significant impact on soybean yield. The persistence of this new pest in existing areas and its...

Planting soybean in the same field that just grew soybean is not recommended. Soybean yield will suffer even before factoring in environmental conditions, weather, and pest/disease pressures. 

Four different studies in Minnesota and Wisconsin have shown a yield decline of at least 5% and...

Farmers may be planning to grow soybeans in 2022 in fields cropped to soybeans in 2021 because of high prices and limited availability of inputs for corn production. Doing this in fields infested with the soybean cyst nematode (SCN) is always a risky proposition. But growing beans on beans in...

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...

The November and the meteorological winter (December-January-February) temperature and precipitation outlooks were recently released by NOAA’s Climate Prediction Center (CPC). Below is a recap of what those outlooks are predicting and the potential impacts those outlooks could have on...

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.

Anhydrous costs are reported to have risen to $850 or more per ton.

Much of Iowa is currently abnormally dry or in some state of drought according to the latest U.S. Drought Monitor. If dry field conditions persist, the potential for combine and field fires this fall could...

As corn has quickly reached maturity, the next hurdle of the 2021 growing season is harvest. Stalk quality will be a concern for fields across that state that experienced the stress of too much or not enough moisture. Alison Robertson recently wrote an...

I got invited to SERF (ISU Southeastern Research Farm) field day last week to highlight corn rootworm management. I was easily distracted when it wasn't my stop and started walking around soybean plots looking for insects. [this is a common occurrence with entomologists!] Soybean was in...

As the 2021 growing season comes to a close, what should you be thinking about in terms of corn disease and how that might impact your harvest plans?

With harvest quickly approaching, it’s time to make sure your combine is prepped and ready for the field. This article published in fall of 2020 has some good tips for...

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...
