Estimating Corn Emergence With Growing Degree Days: Data from May 7, 2021

With corn planting well underway in South Dakota, the next step is monitoring its emergence. One of the factors that can speed up or delay corn emergence is air temperature.

Should I Get Rid Of My Dandelions?

While there is much appeal to having a lawn that is free of other plants, there can be benefits to having some early-season diversity. Some weeds that are sprayed out of lawns, including dandelions, can serve as early-season food sources for pollinators.

Cabbage White Butterflies Are Here!

Keep an eye out for cabbage white butterflies in your garden. These butterflies lay eggs on the underside of the vegetable leaves. Once the eggs hatch, their caterpillars feed on cabbage, broccoli, Brussel sprouts, cauliflower, kale, turnips and radishes.

Wireworms in the Garden

With warming soil temperatures, overwintering wireworms have become active throughout South Dakota. Wireworms are soil-dwelling insects that can be pests of germinating seeds, seedlings and root crops.

Using Data for Better Seed Selection

As harvest wraps up across the region, winter preparation and planning for next year begins. Yield trial results are a key component when making sound seed selection decisions.

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.

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?

Beets: How to Grow It

Beets are commonly grown for their bulbous roots, but their tops can also be harvested for greens, and they are an excellent source of Vitamin A as well as calcium. They grow best in the cooler temperatures of spring or fall.
