Why’s My Alfalfa Field Turning White?
There have been a lot of reports of alfalfa fields in South Dakota with a white or light-brown canopy. This discoloration is the result of extensive alfalfa weevil larvae feeding.
Grassland Fertilization: Exotic Grass Planting Case Studies - McPherson and Jerauld Counties
Our previous installment of this series discussed the effects of fertilization on native grassland plantings. This last installment addresses the options for fertilization on low-diversity exotic grassland plantings.
Grassland Fertilization: Native Grass Planting Case Study - Codington County
Management goals of planted grasslands are an important driver in the consideration of whether fertilizer applications will be beneficial or harmful. Here, we will discuss various plant communities and the impact of fertilization on each.
Grassland Fertilization: Native Pasture Case Study - Hamlin County
Whether fertilization pays or not depends on the species present, the past management history and the type of grazing strategy. This study compares two very different plant communities that represent typical pastures and management schemes in this area.
Alfalfa Weevil Activity Prediction Update: May 27, 2021
Alfalfa weevil activity is still being reported across much of the state. Although the degree day estimates for South Dakota indicate that much of the state has populations that are pupating, these estimates are not accurate. Scouting should continue throughout South Dakota.
Using the ‘Grazing Stick’ To Assess Pasture Forage
Assessing pasture forage is a key step in planning grazing strategies. A grazing stick is a tool that uses simple math and measurements to determine herd size, stocking rates and available grazing days. We will address how to use a grazing stick in this article.
Alfalfa Weevil Activity Prediction Update: May 20, 2021
This week we accumulated degree days for alfalfa weevils at a rapid rate. As a result, we observed many areas of the state potentially move through more than one larval life stage.
Haul the Feed or the Cows
Reduction in pasture forage availability may require producers to decide between hauling feed or hauling cows. Learn how to decide which option is best for your operation.
Impacts of Drought on Soil, Water, Forage and Livestock Grazing Systems
Grazing systems are complex, because soil, water, forage and livestock components are interconnected and affect each other. Producers can put themselves back in the driver’s seat by developing annual systems-level grazing plans for favorable and unfavorable situations.
Alfalfa Weevils Are Active, and It’s Time to Scout
Scouting and managing alfalfa weevils when they reach the determined thresholds can prevent yield loss and encourage healthy regrowth of infested alfalfa stands.
