Numerous studies have been conducted over the last 40 years on soybean combine losses which show that yield loss can be as high as 15 percent.

When taking a plant sample for soybean nutrient analysis, it is important to take the right part of the plant at the right growth stage and send it to the lab in the right way for proper results
The new Fusarium (Scab) Head Blight Prediction Center is now up and running. The purpose of this Assessment Tool is to provide producers and crop consultants with a Fusarium Head Blight (FHB/scab) risk assessment tool which leads up to and includes flowering (anthesis).
Dormant seeding is when a crop is placed in a soil long before soil temperatures and/or moisture conditions are going to allow the seed to germinate and grow. This technique is commonly used for plants like native grasses and forbs. It is less common with grain crops.
To legally sell wheat seed in South Dakota, a standard test—following Association of Official Seed Analysts (AOSA) seed testing protocols, for germination, purity, and noxious weeds—is required. This standard analysis, plus a seed count provides information needed to determine the seeding rate.
Many Midwest producers have limited options for their primary forage source this year and, must utilize ear-less corn stalks as silage for their in livestock feeding systems. Despite the lack of ears on stalks in some areas the resultant corn stover silage is still expected to contain 80% of expected level of energy under normal growing conditions.
A five year study conducted in southwestern South Dakota evaluating seven winter wheat varieties over four planting dates from September 15 to November 1 showed that delayed planting decreases yields. The results determined that planting mid September to the first of October consistently had the highest grain yield over the duration of the experiment.
Crop rotation has long been recognized as a standard component of integrated pest management in cropping systems.
If you are growing oats this year for grain, be sure to scout and plan a fungicide application to protect the oats from crown rust.
Over the growing season, solar radiation, air temperature and plant size are the dominant factors in determining evaporative demand and the rate of water use by wheat. Water use can vary dramatically on a day-to day basis, depending on climate and wheat health.
