Can You Break the Hydro-illogical Cycle?

Regardless of the time of year, it is critical to start thinking about the next drought before we are in it. Learn some key strategies for breaking the Hydro-Illogical Cycle by leveraging drought motioning resources and creating a plan for your operation.

Ranching and Prairie Streams: Why Riparian Areas Matter

For many producers, riparian pastures are essential to their operations. However, land managers need to balance grazing and utilization needs with riparian health for the long-term benefit of their operation.

New Technology for an Old Problem

One of the last projects I was involved with as coordinator for the Lower James River Watershed Project was the installation of a deep pit monoslope barn for a feedlot operation near Alexandria, SD. A deep pit confinement barn is a manure storage system that employs slatted flooring with pit manure storage underneath.

Nitrates and Livestock Water Quality

Nitrate poisoning is something we think about with forages such as millet, oats, corn, sorghum, sudan, kochia and others that have been fertilized or if there is a drought, but water can also be a contributing factor.

Blue-Green Algae and Livestock

With warmer temperatures, the conditions are right for blue-green algae blooms. Different species of blue-green algae contain various toxins, which can poison livestock, resulting in rapid death.

Backyard Biodiversity: Nest boxes for native bees

Many of our native bee species are solitary. In order to ensure that these kinds of bees spend more time in our yards and gardens, it is important to make sure we include places for them to nest.

Water Use by Plant Stage

Over the growing season, solar radiation, air temperature and plant size are the dominant factors in determining evaporative demand and the rate of water use by wheat. Water use can vary dramatically on a day-to day basis, depending on climate and wheat health.

Soil Testing for Vineyards in South Dakota

Not all soils are conducive to growing quality grapes, so prospective vineyard sites should be tested before a decision is made to plant grapes. Tests can identify soils that are either too high in pH, salts, or salinity, or that are “too rich” (too high in organic matter and nitrogen) for grapes. In addition, testing before planting allows for the incorporation of nutrients—such as phosphorus—that do not move easily through the soil to plant roots.
