As harvest is starting to wrap up in Iowa and the cooling temperatures are making their appearance right in time for fall activities, it’s time to think of our next field operation, anhydrous ammonia. Anhydrous ammonia is an effective nitrogen fertilizer for Iowa corn production, but successful application takes more than an open field and available equipment.

Harvest is often a race against time. Delayed harvest can increase grain losses, reduce grain quality, and create additional weather risk. Wheeling on wet soils during harvest and grain handling may be unavoidable this fall. Iowa has received higher precipitation over the months of July, August and September than average. When soil is wet, the soil bearing capacity is weak, with top and subsoil layers vulnerable to soil compaction.

As harvest progresses, keep in mind that sampling fields for soybean cyst nematode (SCN) after harvest is a great way to finish up the crop season. Results of fall samples from corn fields can be very useful in developing or adjusting SCN management plans for 2027 if soybeans will be grown in the fields. Alternatively, fall sample results from soybean fields may provide information that helps explain 2026 soybean yields. This article provides additional details on how to collect meaningful SCN soil samples and where to send them for processing.
