Interseeding Cover Crops Effect on Corn and Soybean Production: 2019

Incorporating cover crops into our cropping systems and moving from conventional tillage to no-till can improve soil organic matter, soil structure, and water and nutrient holding capacity of our soils.

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.

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.

Farm Practices That Improve Soil Health: Cover Crops and Crop Residues

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.

Farm Practices That Improve Soil Health: Planting Switchgrass on Marginal Lands

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.

Farm Practices That Improve Soil Health: Crop Rotations and No-Till

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.

South Dakota Pest Management Guides

The South Dakota Pest Management guides are now available for free. The guides offer recommendations for controlling weeds, insects, and diseases in a variety of South Dakota crops.

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.

Black Grass Bug Activity Expected in Coming Weeks

Spring green-up is the time to be watching for black grass bug activity. Large populations of this early-season pest can cause severe damage to pasture (up to 90% forage reduction) and infest the edges of wheat fields.
