Strategies for and Implications of Long-Term Grain Storage

Author:  Comments Off on Strategies for and Implications of Long-Term Grain Storage

Several questions have come in this week regarding longer-term grain storage. Commodity prices for both corn and soy have prompted this question as producers look to 2025 futures. How long grain can be safely stored without a degradation in quality depends on several factors.

Soybean Seed Quality Following Hurricane Helene

Author:  Comments Off on Soybean Seed Quality Following Hurricane Helene

I want to enter into this conversation with great humility and respect, as many of our neighbors and fellow Tennesseans have suffered great loss in the wake of Helene. As devastating as crop loss and seed damage can be, many have lost much more.

Nevertheless, as we have returned to soybean harvest following hurricane Helene, myself and producers alike are experiencing a severe decline in soybean seed quality. I have heard reports that elevators are rejecting some loads entirely, and of dockages as high as $2 bushel-1 for others. With average yields and commodity prices not where we’d like for them to be in 2024, this is definitely not the finish we were hoping for.

Nitrogen loss potential in wet corn fields

From late April and throughout the month of May, many parts of Middle and West TN have received persistent rainfall that is well above the average for this period. These rains have produced persistently wet soil conditions and have coincided with sidedress N fertilizer application where most or all of the recommended N is applied. With this much rain, there is potential for N loss. Continue reading


Harvest Aid for Soybean

Author:  Comments Off on Harvest Aid for Soybean

Soybean cultivar selection in the Mid-southern U.S. has shifted toward early maturing, indeterminate maturity group (MG) 4 varieties. This shift has increased the adoption of harvest aid application in these environments. Leaf retention and green stems and pods in earlier maturing, indeterminate varieties after physiological maturity can delay harvest. Application of harvest aids also assists in late-season weed control and may allow producers to achieve earlier crop delivery at an above-base premium. Continue reading


Irrigation Termination Decisions for Corn and Soybean

Author: and  Comments Off on Irrigation Termination Decisions for Corn and Soybean
As we approach the end of July, much of our corn and some of our soybean acres are in the latter portion of their respective reproductive growth stages. As we progress toward physiological maturity, lets revisit irrigation termination decisions for these two crops.
