Grazing Intensity Impacts on Pasture Carbon and Nitrogen Flow

Grazing Intensity Impacts on Carbon Sequestration in an Alpine Meadow on the Eastern Tibetan Plateau

Livestock grazing has the potential to substantially alter carbon (C) storage in grassland ecosystem. In this study, we evaluated the soil-plant system C (0-30cm) under three different grazing intensities by yaks (light: 1.2, moderate: 2.0, and heavy: 2.9 yaks/ha) in alpine meadow on the eastern Tibetan Plateau. Soil organic C at 0-30cm depth and total plant components C increased from light gr...

Ground cover impacts on nitrogen export from manured riparian pasture.

Maintaining ground cover of forages may reduce the export of nitrogen (N) from pastures. The objective of this work was to determine the effect of ground cover on N export from pastured riparian areas receiving simulated rainfall. Plots were established on two adjacent sites in the North Carolina Piedmont: one of 10% slope with Appling sandy loam soils and a second of 20% slope with Wedowee san...

Impacts of grazing systems on soil compaction and pasture production in Alberta

Donkor, N. T., Gedir, J. V., Hudson, R. J., Bork, E. W., Chanasyk, D. S. and Naeth, M. A. 2002. Impacts of grazing systems on soil compaction and pasture production in Alberta. Can. J. Soil Sci. 82: 1–8. Livestock trampling impacts have been assessed in many Alberta grassland ecosystems, but the impacts of animal trampling on Aspen Boreal ecosystems have not been documented. This study compared...

Effects of stocking and nitrogen fertilization rates on steers grazing dallisgrass-dominated pasture.

To compare the performance of steer calves managed under different stocking rates (SR; 3.7, 6.2, 8.6, and 11.1 steers/ha for 140 d; chi(I1)) and N fertilization rates (112, 224, and 336 kg of N/ha; chi(I2)) in May 1996, 1997, and 1998, 72 steer calves (BW = 231 +/- 2.5 kg) were assigned randomly to one of 12 0.81-ha dallisgrass (51%)/common bermudagrass (32%) pastures. One-third of the fertiliz...
