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?

Counties Designated as Disaster Areas and Qualify for Other Programs

Five South Dakota counties have been given disaster declarations due to dry summer conditions. This declaration gives producers in these counties and those in contiguous counties access to USDA-FSA emergency loans.

How Early Is Too Early to Plant Row Crops?

Although it can be tempting to get a head start with row crops, it is important to be mindful of soil temperatures and the associated risks with planting early.

Organic Herbicides: Garden and Flower Bed Weed Control

Many South Dakota homeowners do not want to use inorganic or synthetic herbicides due to potential health impacts. Organic herbicides can be a useful tool for weed control when combined with other management practices.

Drought Conditions Magnifying Impact of Black Grass Bugs

With much of South Dakota continuing to experience moderate-to-extreme drought conditions, black grass bugs could become a concern in some areas. Large populations of black grass bugs can cause severe damage to pasture.

Crop Tolerance to Soil Herbicide Residual

Some herbicides can persist in soil, especially dry soil. Herbicide carryover could be an issue in 2021 across the state depending upon last year’s moisture levels and field conditions.

Weed Control in No-Till Gardens

Mulch is the key to successful weed control in no-till gardening. It is best to start a no-till garden in the fall to give applied mulch the time to breakdown and suppress any weed growth.
