The first step in initiating seed germination is imbibition of water. As the seed takes on water (up to 30 percent of its own weight for corn and 50 percent for soybeans!), enzymes within the seed start converting starch from storage forms into forms that will help feed the newly awakened embryo. Cell membranes in the seed have to rehydrate to re-initiate growth; that process can go awry in cold temperatures.

The planter pass is the most important pass of the season. It sets the stage for everything else. Equally important is the time spent doing planter maintenance, prep, and set up. Each planter or row unit manufacturer has specific guidelines as to how to set and adjust specific equipment, so always reference the owner’s manual, but the following holds true for most planting implements.

Winter wheat breaks dormancy if there is a two-week period with an average temperature of at least 41°F. As soon as the plants resume growth, you need to get back out in the field so that you can make critical decisions about nitrogen, insecticide, and fungicide, and most importantly, preserving yield potential.

Farming at a profit is more challenging when grain prices are low. Producers with owned ground and sound management can likely farm at a profit albeit at a narrower margin than previous years. Producers shelling out high cash rents will find it more difficult to operate at a profit even with sound management. Many paying high cash rent will operate at a loss. This is especially true if looking at profitability in a “site-specific” manner — considering profit/loss variability across a field or operation.

Soil surface compaction can affect soybean plant height, root growth and development, pod set, and yield

When a farmer ends up with damaged grain at harvest, the best thing to do is sell it as quickly as possible. However, sometimes due to the obligation to fulfill contracts or the ability to utilize bin space to capture carry in the market, it becomes necessary to store damaged grain.

We have received a lot of phone calls about down corn throughout the season.
Early on, this issue was primarily caused by saturated soils and heavy winds that pushed the corn over at the root system.

There are numerous stalk rots that affect corn in mid to late season. Weather, nutrition and genetic disease tolerance all play major parts in the disease cycle. Plants move nutrients from the stalks to the ears during grain fill. High yields mean heavier ears. These two phenomena combined can make stalk quality issues a problem even in very high-yielding areas.

Tar Spot is a new phenomenon in the US. It is caused by a fungus called Phyllachora maydis, native to Central America. Tar Spot had only been identified in very isolated geographies in the U.S. until the summer of 2018. In Central America, the yield-robbing form of Tar Spot forms a complex with two other plant pathogens, neither of which have been documented in the U.S. It is unknown whether the Tar Spot organism is forming a pathogenic complex with other species present in the Midwest.

High rainfall and warm temperatures after maturity physically cause the soybean pod to swell and shrink. Any structural weakness in the pod from diseases or insect feeding will allow moisture into the pod where it affects the soybean itself. The pods then split open from the physical stress of swelling with moisture. Soybeans exposed to warm temperature and high moisture are also subject to germinating in the pod. All soybean varieties are susceptible to damage in exceptionally wet years.

We are having a particularly wet harvest in many areas. Keep an eye out for deteriorating grain quality. Here’s a good reference guide from Steve Gauck on ear molds in corn.

When scouting corn, it's important to focus starting now through brown silk, or the R2 growth stage. This is the most important time to protect the plant as it's going through grain fill.

Data has shown that the best time to apply fungicides on soybeans is at the R3 growth stage.

High heat and humidity, especially like we have experienced this summer, creates a perfect breeding ground for diseases such as gray leaf spot. Because of this, you may find that your corn fields are in need of a fungicide application.
In this latest agronomy update, I am evaluating the overall differences we have seen in our Wheat Planting Date Study.
