Backgrounding Beef Calves on Cover Crops May Improve Steak Tenderness

Can short-term backgrounding diets of beef calves have long term impacts of meat quality? Recent research from the meat science team at South Dakota State University says, “Yes.”

Using Annual Cover Crops and Forages in Lieu of Row Crops

Although there are many factors to take into consideration, annual forages and cover crops can be an excellent tool to mitigate challenging planting seasons.

Herbicide Considerations for Cover Crop Planting in 2019

Long residual pre-emergent or early post-emergent herbicides may cause stand reduction or complete failure of cover crops. Depending on efficacy of the herbicide, each situation can both affect in-season and/or post-harvest cover crop establishment.

South Dakota Herbicide Damage

As the spray season starts, it is always good to be aware of resources and testing facilities where you can send in possible herbicide-affected plant samples. SDSU Extension offers suggestions on how to handle possible herbicide damage situations as well as recommended labs that receive plant matter samples to test for herbicide residues.

Herbicide Interactions With Cover Crops After Oats

After oats have been harvested, options exist to keep a living root in the soil. This can be done through growing cover crops. In 2018 an on-farm trial was preformed near Salem, South Dakota to observe how cover crops grown after oats would germinate after common herbicides had been applied.

Perennial Solutions for Alkali Areas

Reclaiming marginal lands, especially those considered saline or sodic can be very challenging and may take many years to accomplish. The key to turning around salt or alkali areas in your fields, begins with getting a living root established in the affected area.

Managing Weeds While Transforming Marginal Land Into Perennial Forages Production

There are currently millions acres across South Dakota impacted by saline and sodic conditions. Research has shown that salt-tolerant perennial grasses are a possible way to bring land back into production.
