Managed grazing in WICST prairies: Tradeoffs between plant functional diversity, forage availability, and resistance to weed invasion

To explore the relationships between plant functional diversity, forage production, and forage quality in native grasslands managed for sequential grazing, managed grazing was employed across a diversity gradient in reconstructed tallgrass prairie communities. A well-established switchgrass monoculture was compared to reconstructed (planted) prairies that had been seeded with varying levels of native plant functional diversity [...] More »

Forage Production and Quality of Restored Prairie Interseeded with Native Legumes

Motivations for restoring tallgrass prairie in the Upper Midwest range from natural resource conservation to developing new forage and cropping systems. Cropping systems based on the tallgrass prairie may be well-suited to providing reliable summer forage for livestock, feedstocks for home heating, electricity production, and ethanol, as well as ecosystem services such as carbon sequestration.

Responses of Shrub Midstory and Herbaceous Layers to Managed Grazing and Fire in a North American Savanna (Oak Woodland) and Prairie Landscape

Worldwide, savanna remnants are losing acreage due to species replacement with shade-tolerant midstory forest species as a response to decades of fire suppression. Because canopy closes grasses and other easily ignitable fuels decline, therefore, fire, when reintroduced after years of absence, is not always effective at restoring the open structure original to these communities. Our [...] More »

Effect of Aeration on Yield and Quality of Pasture Forage at the Krusenbaum Farm.

Forage yield has been lower than expected on the intensively managed pasture at the Krusenbaum farm in recent years. One hypothesis was that heavy stocking rates have resulted in surface soil compaction adversely affecting forage yield and through reduced legume growth-forage quality as well. It was decided to see if mechanical aeration of the surface [...] More »

WICST Intensive Rotational Grazing of Dairy Heifers in 1997 and 1998

Of the three dairy systems represented in the Wisconsin Integrated Cropping Systems Trial (WICST), rotational grazing is the lowest input system. Pastures were established at the Lakeland Agricultural Complex (LAC) and the Arlington Agricultural Research Station (ARS) in 1990. Initially, species included red clover, smooth bromegrass and timothy; later, orchardgrass, perennial ryegrass and [...] More »
