What is a Hydrologic Unit Code (HUC)?

HUC is the acronym for Hydrologic Unit Code. It is a hierarchical land area classification system that is based on surface hydrologic features in a standard, uniform geographical framework.

Multiple Rounds of Severe Weather Bring Heavy Rainfall, High Winds, and Soil Erosion

A combination of tillage, no residue, and lack of crop canopy can lead to severe erosion and topsoil loss in the face of extreme weather patterns in the spring. The most effective strategy for producers to adapt to these extreme events is to improve soil health.

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.

Temperature and Herbicide Performance

In South Dakota, the spring can come with a wide range of temperature fluctuations. This will affect the performance of burndown herbicides. Depending upon the target weed, type of herbicide and application rate, there will likely be decreased weed control in cooler temperatures.

How to Stop Drift

The goals of applying any crop protection products include: increasing effectiveness, mitigating drift, and maximizing profits. We will focus on mitigating drift, even though all three interact with each other.
