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.

A picture of a lawn showing a ring of dark green grass in the middle of the lawn due to fungi in the soil.

Fairy Rings in Lawns

Seeing greener grass in circular pattern in your lawn? This is not due to uneven fertilizer application, but rather due to a fungi feeding on decomposing matter and releasing nitrogen in the affected areas.

Wheat tillers with lower leaves covered with tan-brown lesions. The ground beneath has wheat stubble from previous wheat crop.

Scout for Tan Spot in Winter Wheat

Tan spot was observed in a few winter wheat fields scouted recently. It is important to scout winter wheat for tan spot and other early diseases developing before deciding to apply an early-season fungicide tank mixed with herbicide.

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?
