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.
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.
Bacterial Leaf Streak of Corn: A New Corn Disease in South Dakota
Bacterial leaf streak, caused by Xanthomonas vasicola pv. vasculorum (Xvv), is a recently discovered disease of corn in South Dakota. The disease was first identified in Nebraska in 2016 but now has been found in the majority of the Corn Belt states. Under favorable weather conditions bacterial leaf streak can develop to reach yield reducing levels. Like any other bacterial disease, once symptoms develop there is little that can be done to control it in the field. However, it is important to correctly diagnose this as a bacterial disease because it can be confused with gray leaf spot which is a fungal disease.
Fungicide Resistance: Risk and Management
What is fungicide resistance?
