Left: Soil from long-term no-till field, exhibiting good soil aggregation through clumping and smaller pieces of soil. Right: Soil from conventionally managed field that included tillage and crop residue removal. Notice the soil is lighter brown, indicating lower organic matter, and the pieces of soil are in larger chunks with no visible indication of clumping or structure.

Organic Agronomy Starting to Impact

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.

Range Roundup: SDSU’s Native Plant Initiative

The SDSU Native Plant Initiative aims to improve our understanding of South Dakota’s native plants, including which ones are best-suited for restoration and production. This information will help guide stakeholders in matching native species to desired restoration outcomes.

Selecting a Calving Season Based on Matching Nutritional Needs and Resources

Choosing the calving season is a complex and highly individual decision for each beef cattle producer. A primary consideration in pasture-based cow-calf operations is choosing a calving season that will best match the forage supply to forage demand.

West Dakota Water Development District Looks To Improve Rapid Creek Water Quality Through Stormwater Mitigation and Erosion Control Projects

Two pilot projects initiated by the West Dakota Water Development District are intended to improve water quality in Rapid Creek by reducing suspended sediment loading over time.

Haul the Feed or the Cows

Reduction in pasture forage availability may require producers to decide between hauling feed or hauling cows. Learn how to decide which option is best for your operation.

Two rows of corn at V5 leaf growth stage looking down from above. Between the corn rows there are 3 separate cotton strips placed on the soil surface just before burial in a 2-inch-deep trench. The cotton strips are numbered for their identification after recovery at three different dates.

Cotton Strip Soil Test: Rapid Assessment of Soil Microbial Activity and Diversity in the Field

Soil has always been considered as a living system due to its biological components: fungi, bacteria and plant roots. Under several ongoing research projects, we started researching how we can use ‘cotton strip assay’ to compare different cover crop mixes to optimize field soil activity and build up better soil health.

Earthworms on the soil surface inside a white hard-plastic ring, after mustard-vinegar solution was drained down through the soil profile forcing earthworms out onto the surface in order to be counted.

How’s Life in the Soil? Ask (Count) the Earthworms.

Earthworms are ‘very special’ creatures on earth, and their contribution in soil nutrient cycling and fertility management has been acknowledged from the beginning of agriculture. So, the question needs to be asked, how can we help improve earthworm populations?
