Planting cover crops and returning crop residues (stover) to the soil both adds nutrients and improves overall soil quality. These practices are common with producers across South Dakota and have been recently studied by researchers to identify how they impact the release of greenhouse gases into the atmosphere.
Switchgrass (Panicum virgatum) is a tall, native, prairie grass that is often seeded on marginal lands in South Dakota. It has gained growing popularity over the past decade not only as a source of biofuel and feed, but also as a method to improve soil properties.

Implementing diverse crop rotations and no-till practices are common suggestions to reduce erosion, control pests, and improve yields. These practices can also improve soil health through an increase in soil carbon levels.
For decades scientists have known that a handful of soil contained more micro-biological organisms than the number of humans on earth. Science is just beginning to discover these organisms and learn about their functions and contribution to their soil ecosystem.

South Dakota Governor Kristi Noem has declared February 21, 2020 Soil Health Awareness Day. Agriculture contributes over 132,000 jobs and 32.5 billion dollars in total output to South Dakota’s economy.
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.
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.
Current events have made decisions around crop options very difficult this spring. Field peas are an option that may have a fit for some producers.
Spring is a busy time for South Dakota farmers and ranchers with planting, calving, and other field preparations. Soil sampling and fertilizing pastures, alfalfa, or other forages might be overlooked.

The Every Acre Counts program through SDSU Extension has developed perennial plant mixture suggestions suited for various types of marginal land situations, including saline, sodic and wet soil areas.
