Title: Animal and plant response on renovated pastures in western Canada: Journal: Journal of Range Management; Authors: D. H. McCartney, J. Waddington, and L. P. Lefkovitch; Date: 1999; Summary: Seeded grasslands in northern Saskatchewan were fertilized or unfertilized, and grazed with continuous, 4-paddock or 6-paddock rotational grazing systems to determine if the grazing season in this area could be extended by using any of these management techniques. Available AUMs and length of grazing season was greatest under the 6-paddock rotational grazing system, intermediate under the 4-paddock rotational system, and lowest under continuous grazing. The increased grazing season length and increased gains per hectare under the rotational systems were probably a result of the increased qua ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Modulation of diversity by grazing and mowing in native tallgrass prairie: Journal: Science; Authors: S. L. Collins, A. K. Knapp, J. M. Briggs, J. M. Blair, and E. M. Steinauer; Date: 1998; Summary: Two long-term field experiments were performed in native tallgrass prairie grassland to assess the effects of fire, nitrogen addition, and grazing or mowing on plant species diversity. In the absence of grazing by bison (Bison bison), or through simulated herbivory in the form of clipping, burning increased the dominance of warm season grasses and reduced plant species diversity. After 9 years of treatment, plots burned annually or burned and fertilized with nitrogen, no longer included any cool season grasses or woody species. With the addition of mowing, burned and fertilized plots retain ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Nitrate levels in shallow groundwater under pastures receiving ammonium nitrate or slow-release nitrogen fertilizer: Journal: Journal of Environmental Quality; Authors: L. B. Owens, W. M. Edwards, and R. W. Van Keuren; Date: 1992; Summary: An intensively managed, grazed grassland system was examined to determine the effects of nitrogen fertilization levels on surface runoff and groundwater on the North Appalachian Experimental watershed near Coshocton, Ohio. Beef cows grazed four pastures rotationally over the 5 years prior to the study from May-October with hay fed in one pasture (previously grazed) from November-April. During this time each pasture received an annual application of ammonia nitrate. For the next 7 years grazing followed the same pattern with the summer grazed pastures receiving increased ammonium nitrate or s ...; Agrovoc Control Words: Riparian zones, Grazing, Water quality; View more details about this article

Title: Prosopis glandulosa growth: Influence of nutrients and simulated grazing of Bouteloua curtipendula: Journal: Ecology; Authors: O. W. Van Auken, and K. J. Bush; Date: 1989; Summary: Van Auken and Bush determined the effects of inter-plant and resource competition on the growth of Prosopis glandulosa, when this shrub was grown in experimental plots with clipped or unclipped Bouteloua curtipendula grass plants. Clipping reduced the biomass of B. curtipendula and increased the biomass of P. glandulosa, suggesting that grazing may enhance the growth and encroachment of shrub species, such as Prosopis glandulosa, in grass-dominated plant communities. The addition of fertilizer to the soil enh ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Effect of defoliation frequency and N-P-K fertilization on maidencane: Journal: Journal of Range Management; Authors: R. S. Kalmbacher, and F. G. Martin; Date: 1988; Summary: Kalmbacher and Martin determine the effects of clipping frequencies and fertilization on maidencane (Panicum hemitomon) forage production, quality, and mineral content in order to determine proper grazing management for this plant. In general, more frequent clipping enhanced forage quality and reduced forage production, tiller density and rhizome yield, especially in the second year of the experiment. Fertilizer was able to overcome the reduction in plant production and tiller density sometimes, but did not affect rhizome yield and in most cases the benefits of fertilizi ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
