Soil and vegetation responses to simulated trampling
Date: 1987
Authors: A. H. Abdel-Magid, M. J. Trlica, and R. H. Hart
Summary: Abdel-Magid et al. used an artificial hoof to simulate 4 levels of trampling intensity typical of continuous and short duration grazing systems, on shortgrass prairie sods, maintained at varying levels of water stress under greenhouse conditions. Ch ...

Seasonal dynamics and defoliation impact on herbage yield in aspen boreal habitats of Alberta
Date: 2003
Authors: N. T. Donkor, M. M. Okello, R. J. Hudson, and E. W. Bork
Summary: Authors used an experimental design to investigate seasonal changes in the live and dead phytomass components of a Bromus inermis-Poa pratensis community, and the effects of initial timing, height, and frequency of clipping on accumulated herbage rem ...

Cattle foraging behavior in leafy spurge (<em>Euphorbia esula</em>) infested rangeland
Date: 1987
Authors: R. G. Lym, and D. R. Kirby
Summary: Cattle foraging behavior was observed over three years on a 121 ha pasture near Leonard, North Dakota. Cattle were grazed season long at a heavy stocking rate (0.53 AUM/ha - 0.61 AUM/ha) in a pasture with four levels of leafy spurge infestation rang ...

Botanical composition, light interception, and carbohydrate reserve status of grazed 'Florakirk' bermudagrass
Date: 2000
Authors: C. G. S. Pedreira, L. E. Sollenberger, and P. Mislevy
Summary: Pedreira et al. determined persistence of the "Florakirk" cultivar of bermudagrass (<em>Cynodon dactylon</em>) at different stocking rates (stubble heights of 8-,16-,24-cm) and management regimes (rest period of 7, 21, 35 days) ...

Date: 1997
Authors: W. L. Stout, S. A. Fales, L. D. Muller, R. R. Schnabel, W. E. Priddy, and G. F. Elwinger
Summary: In a Pennsylvania field study, Stout et al. measured NO<sub>3</sub>-N leaching loss from spring-, summer-, and fall-applied urine and summer-applied fecal beneath N-fertilized orchardgrass (<em>Dactyls glomerata</em>) using dr ...
