Title: The influence of harvest management and fertilizer application on seasonal yield, crude protein concentration and N offtake of grasses in northeast Saskatchewan: Journal: Canadian Journal of Plant Science; Authors: D. H. McCartney, S. Bittman, and W. F. Nuttall; Date: 2004; Summary: In Saskatchewan, McCartney et al. compared annual and seasonal productivity, protein concentration, and N offtake by several adapted grasses as influenced by harvest management and fertilizer application in the central Aspen Parkland. Meadow bromegrass (Bromus riparius) had both high yield and relatively uniform seasonal production, making it a desirable grass for pastures in the central Parkland region. It also offered the most late-season yield. The high yield of green needlegrass (Nassella viridula) under multiple harvests suggests that this gras ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Seasonal dynamics and defoliation impact on herbage yield in aspen boreal habitats of Alberta: Journal: Canadian Field Naturalist; Authors: N. T. Donkor, M. M. Okello, R. J. Hudson, and E. W. Bork; Date: 2003; 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 removal in a boreal aspen forest in Alberta. Maximum summer yield, rapid loss of green herbage late in the growing season, and dry matter losses in the standing dead and fallen litter pools over winter characterized the seasonal changes in herbage phytomass on this aspen boreal grassland. The amount of herbage harvested was affected by initial clipp ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Grazing intensity impacts on pasture carbon and nitrogen flow: Journal: Journal of Range Management; Authors: V. S. Baron, E. Mapfumo, A. C. Dick, M. A. Naeth, E. K. Okine, and D. S. Chanasyk; Date: 2002; Summary: In this 3-year study, Baron et al. determined the effects of increasing grazing intensity on carbon (C) and nitrogen (N) cycling in a meadow bromegrass (Bromus riparius) pasture through vegetative and nutritional measurements and fecal and urinary output equations. Increasing grazing intensity increased the nutritive value of bromegrass, but decreased the aboveground dry matter and C production in the pasture. As grazing intensity increased, the amount of dry matter, C, and N remaining after the grazing season was reduced, while fecal C input and excreted urine N were increased. Carbon and ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Grazing impacts on soil nitrogen and phosphorus under parkland pastures: Journal: Journal of Range Management; Authors: V. S. Baron, A. C. Dick, E. Mapfumo, S. S. Malhi, M. A. Naeth, D. S. Chanasyk; Date: 2001; Summary: Soil nutrients were measured for 4 years in pastures under heavy, moderate, and light grazing intensities, that were seeded with one of three species (smooth bromegrass (Bromus inermis), meadow bromegrass (Bromus riparius) or winter triticale (X Triticosecale), to determine the effects of grazing intensity and forage species on soil N and P levels. After the third year of grazing, increasing grazing intensity increased nitrate, mineral N, and phosphorous levels in the soil, most likely because 2.4x more feces was deposited on heavily grazed pastures than on lightly grazed pastures.

Title: Season-long grazing of seeded cool-season pastures in the Northern Great Plains: Journal: Journal of Range Management; Authors: J. F. Karn, R. E. Ries, and L. Hoffmann; Date: 1999; Summary: Karn et al. compared animal gains, and forage production and utilization at two stocking rates (moderate and heavy) on flat and rolling native grasslands with seeded smooth bromegrass (Bromus inermis), western wheatgrass (Pascopyrum smithii), and crested wheatgrass (Agropyron desertorum) pastures grazed season-long by cattle. On all pasture types, cattle spent more time grazing at the heavy stocking rate compared to the low stocking rate, possibly because of the lower forage production, which also reduced average daily gains at th ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

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: Effects of management on species dynamics of Canadian aspen parkland pastures: Journal: Journal of Range Management; Authors: J. Waddington, D. H. McCartney, and L. P. Lefkovitch; Date: 1999; Summary: Aspen parkland vegetation response to continuous and rotational grazing combined with fertilizing and seeding were determined in this study. Vegetative cover was greater on the continuously grazed pastures than rotationally grazed pastures. Pastures managed with four-field rotational grazing had greater cover than pastures managed with six-field rotational grazing. Changes in species composition occurred in all pastures, regardless of grazing system or fertilizer and seeding treatments applied. However, overgrazing caused increases of less desirable species in the continuously grazed pastu ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Persistence of cool-season grasses under grazing using the mob-grazing technique: Journal: Canadian Journal of Plant Science; Authors: D. H. McCartney, and S. Brittman; Date: 1994; Summary: The objective of this study was to evaluate the persistence of several cool-season grasses adapted to northeastern Saskatchewan under contrasting grazing pressures using the mob-grazing technique. Ground cover declined more rapidly under intense than under light grazing, but no interaction was found between grazing intensity and grass germplasm. The ground cover of the seeded grasses generally declined but at different rates during the trial, giving a significant grass x year interaction. Carlton smooth bromegrass (Bromus inermis) declined significantly more than Parkwa ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Influence of grazing pressure on forage quality and intake by sheep grazing smooth bromegrass: Journal: Journal of Animal Science; Authors: H. G. Jung, and T. Sahlu; Date: 1989; Summary: Jung and Sahlu determined the effects of sheep grazing at two different stocking rates on available forage, forage quality, diet quality, and animal intake and weight gain. Forage quality declined over time in both pastures, but pastures grazed at the high stocking rate had less available green forage for sheep grazing. Due to the limited available forage, animal gains, forage intake and diet quality and digestibility was lower in pastures with high stocking rates. These results indicate that grazing smooth bromegrass (Bromus inermis) pastures at higher stocking rates d ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article

Title: Comparison of heifer weight gains and forage quality for continuous and short-duration grazing systems: Journal: Journal of Range Management; Authors: H. G. Jung, R. W. Rice, and L. J. Koong; Date: 1985; Summary: Jung et al. compared the effects of continuous grazing and short-duration grazing, at increased stocking rates, on animal gains, and forage quality and production in smooth bromegrass (Bromus inermis) pastures. In the first year of this study, continuous and short-duration grazed pastures were stocked at the same rate, resulting in similar animal gains and forage quality between pastures, but greater available forage was in rotationally grazed pastures. In the second year of the study, the stocking rate was increased on rotationally grazed pastures to utilize the increas ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
