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.
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.
Cattle and Land Conservation in South Dakota
Analysis of results from a 2017 South Dakota farmer survey reveals that cattlemen tend to be more land conservation oriented than their grain farming counterparts.
