Cover crops to improve soil health in the North American Great Plains

Short communication Soil response to long-term grazing in the northern Great Plains of North America

Grazing management affects ecosystem function through impacts on soil condition. We investigated the effects of long-term (over 70 years) grazing on soil properties and nitrous oxide (N2O) emission within a moderately grazed native vegetation pasture (MGP), heavily grazed native vegetation pasture (HGP), and a fertilized crested wheatgrass (Agropyron desertorum (Fisch. ex. Link) Schult.) pastur...

Human Responses to Middle Holocene (Altithermal) Climates on the North American Great Plains

H w p The climate of the Great Plains during the middle Holocene aried considerably, but overall it was marked by a north–south radient of increasingly warmer and drier conditions, with a reuction in effective moisture, surface water, and resource abunance, and an increase in resource patchiness, sediment weatherng, erosion, and aeolian activity. Pronounced drought conditions ere most evident o...

North American Indians: Indians of the Plains

THE PLAINS The Plains region, an area delineated by the Rocky Mountains on the west; the Canadian provinces of Alberta, Saskatchewan, and Manitoba on the north; the Mississippi River on the east; and the Gulf of Mexico on the south, is home to philosophies, traditions, and ways of life that are some of the most varied and complex in the United States. The Great Plains measure 1,125,000 square m...

Forum Effects of Grazing Pressure on Efficiency of Grazing on North American Great Plains Rangelands

Comparisons of stocking rates across sites can be facilitated by calculating grazing pressure. We used peak standing crop and stocking rates from six studies in the North American Great Plains (Cheyenne, Wyoming; Cottonwood, South Dakota; Hays, Kansas; Nunn, Colorado; Streeter, North Dakota; and Woodward, Oklahoma) to calculate a grazing pressure index and develop relationships for harvest effi...
