Standing Corn Considerations
The January 2020 South Dakota Crop Progress Report indicated four percent of S.D. corn acres remain in the field. Given the record rainfall of 2019, current snow pack levels and the 3-to-6-month precipitation forecasts, farmers will likely be dealing with a wet spring in 2020, thus making the removal of those acres important but hard to accomplish.
Estimating Corn Yield in the Field
As a result of late planting and inconsistent weather, both in-field and across-field variations have been significant this year in South Dakota. Even on highly productive land, it is expected for corn yields to vary significantly. Estimating corn grain yield prior to harvest can help growers make management decisions, especially storage and marketing.
Corn Grain Moisture Discount: Why and How Much?
Corn marketed at the standard moisture content of 15.5% and 56 pounds per bushel typically contains 47.3 pounds of dry matter and 8.7 pounds of water. At harvest, a producer has to decide whether to sell (or even store) his corn at ‘as is’ moisture content or mechanically dry it before taking it to the buyer.
Valuing High-Moisture Corn and Earlage
A key advantage to using commodities that meet standard specifications and are frequently traded is that it is very easy to establish an economic value that is accepted by most users. The marketplace sets the value of corn, and other feedstuffs on a daily basis, provided those products meet some set of standard specifications.
A Case of Mistaken Caterpillar Identity
Tweets about European corn borer (Ostrinia nubilalis) caterpillars in the stems of conventional corn and feeding in the whorls of corn are crossing my Twitter feed. Unfortunately, there is a problem with some of these tweets. Not all of the caterpillars that are being identified as European corn borer caterpillars are actually European corn borer caterpillars!
Storing Wet and Modified Distillers Grains
One of the primary challenges for livestock producers in the coming months could very well be feedstuff cost and availability due to the fact that the corn planted acreage and crop progress are both well behind normal benchmarks. One opportunity that might help cattle feeders proactively secure feed supplies would be storing wet or modified distiller’s grains now to be fed at a later date.
Black Cutworm Caterpillars Are Actively Feeding in South Dakota
We received numerous reports this week of small holes in V1-V2 corn plants. The holes are the result of early instar cutworm caterpillar feeding and, more specifically, black cutworm caterpillars. After hatching, black cutworm caterpillars initially feed on the leaves. As they develop and become larger, they pose a clipping or cutting threat to corn.
Corn Production Costs in the Northern Great Plains
Supply and demand regulates U.S. agricultural and non-agricultural markets all the time. Prices increase when scarcity of a certain item is anticipated. Similarly, prices drop if the market is saturated because of oversupply or there is a reduced demand for the product.
Watch Corn for Bronzed Cutworm Activity
Bronzed cutworms are not a common pest of corn in South Dakota. However, they can become an issue when corn is planted into areas that were previously grassland. Like its name implies, bronze cutworms feed on corn above the soil surface, which often results in cutting or clipping.
Monitor Newly Emerged Corn for Black Cutworm Activity
There are several important insect pests that can severely injure corn during the early vegetative stages. One of these pests is the black cutworm. Although black cutworm caterpillars injure corn by feeding on leaf tissue, the serious damage occurs when caterpillar feeding results in the cutting of young corn plants.
