Trigger Dates: Critical Decisions for Drought Management

Having a drought plan in place ensures that you can overcome the inhibitions surrounding a drought response, the basis of which is figuring out trigger dates.

Drought Planning

A drought plan will be an essential component to your overall grazing plan, as it provides guidance in making decisions during critical times when forage may be lacking.

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.

Management-Intensive Grazing Plays a Key Role in Expanding Grass-Based Agriculture

By improving livestock carrying capacity and reducing feed costs, grazing strategies at greater management intensity have the potential to improve grass-based livestock production profits.

Ready, Set, Manage Hay Differently

Feed is expensive and sometimes hard to find. Pasture prices, harvest expenses, hauling and waste add to the total feed bill. Evaluate your forage situation this winter and make changes that improve your profitability.

Creating Management Zones Using Electrical Conductivity

The first step to practicing zone management is to identify the variations that control yield. There are various methods for characterizing soil variations within a field, and among them, electrical conductivity measurement is one of the most-reliable.

Introduced Grasses and Forbs

While native grasslands contribute greatly to the integrity of the overall grassland community in South Dakota, the use of introduced grasses has proven a popular alternative for some producers.
