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 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?

S.D. Producers’ Willingness To Adopt Patch Burn Grazing vs. Winter Patch Grazing

Patch-burn grazing and winter patch grazing are heterogenous rangeland management practices that aim to increase the variety of grass composition to benefit wildlife and maintain livestock production. To learn about producers’ desire to adopt these practices, we conducted an online survey between November 2019 and January 2020.
