Marestail growing abundantly in a soybean field.

Marestail Fall Control

Marestail (also known as horseweed) is considered either a winter annual or biennial species that is often difficult to identify at the rosette stage. In the Dakota’s, marestail will germinate in the fall and bolt in the spring.

Low Temperatures During Soybean Maturity

This year, we had a slow soybean planting due to high rainfall in spring. This was followed by below normal temperatures for most of the growing season, which delayed soybean growth and development. This brings up a question about what these low temperatures will do to soybeans that are in the field.

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.

Weaning Calves on Cover Crops

What do we do if it is time to wean calves, but the pen isn’t ready? That can be a real concern during wet fall seasons, such as 2019. Putting calves into muddy pen conditions is far from desirable, but holding calves on the cows deep into fall increases the risk of adverse winter weather and tends to pull body condition off the cows.

Assess for Corn Stalk Rots

Several corn fields are beginning to show stalk rot and top dieback symptoms. Stalk rots cause the entire plant to die prematurely, which can lead to plants lodging under windy conditions making harvesting problematic.

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.

Ergot in Western Wheatgrass and the Potential Effects for Winter Grazing

2019 has been a year fraught with challenges for ranchers across South Dakota. Abundant precipitation is usually a blessing, however, wet conditions coupled with a cool spring followed by warmer temperatures has caused another problem across the rangelands of South Dakota: ergot poisoning.

Climate Adaptability of Winter Wheat

For most of us, wheat is wheat. However, there is a distinct difference between spring and winter wheat, even though the vegetative characteristics of these two wheat types are very similar.

Gibberella and Fusarium Ear Rots Developing in Corn

Corn ear rots are one of the last diseases to scout for in the corn growing season, and sometimes they are ignored or forgotten entirely. Ear rots can cause yield loss in the form of grain quality at harvest, but also cause losses during storage.

Farm Practices That Improve Soil Health: Integrated Crop-Livestock Systems

An integrated crop-livestock system can provide an alternative management strategy that benefits producer’s income, soil health, and the environment—all while increasing production.
