  Yield Increases from Nitrogen on Native Range in Southern British Columbia

  Mason, J. L.; Miltimore, J. E. (Society for Range Management, 1969-03-01)

  Response of native range to nitrogen fertilizer has been variable in the province of British Columbia, Canada. Yields have been approximately doubled at many sites reported, but at others virtually no increase has been obtained. It is therefore of interest to report results at 9 additional locations. Average yields from 7 locations over periods from 1 to 4 years from a single fertilizer application were 507 lb/acre without fertilizer, 701 lb from 60 lb/acre N and 880 lb from 240 lb/acre N. Yield increases from 60 lb N averaged from 4 locations declined from 68% in the first year to 35% in the second, 14% in the third, and 6% in the fourth. However, yield increases from 240 lb N remained high with 73% increase the first year, 58% in the second, 92% in the third, and 101% in the fourth year. Cost of the increased yield ranged from $6.40 to $98.00/ton.

  Yield of Crested Wheatgrass Following Release from Sagebrush Competition by 2,4-D

  Robertson, J. H. (Society for Range Management, 1969-07-01)

  Rate of increase in yield of crested wheatgrass following use of herbicide on associated sagebrush was measured over four years, including the year of treatment. Significant increases in yield, which were probably worthwhile economically, did not begin until the third year after spraying.

  Why Proper Grazing Use?

  Anderson, E. W. (Society for Range Management, 1969-09-01)

  Proper grazing use is paramount in attaining efficiency of rangeland production. Numerous scientific studies provide the basic reasons for practicing proper use. Results of grazing intensity studies are being reported from the West. The reasons for proper grazing use are emphasized. The benefits are enumerated.

  Water Use, Adaptability, and Chemical Composition of Grasses Seeded at High Elevations

  Tew, R. K. (Society for Range Management, 1969-07-01)

  Soil moisture depletion varied directly with extent of top and root growth of five grass species seeded on four areas between 6,500 and 8,500 ft in northern Utah. Smooth bromegrass and intermediate wheatgrass had greater root and top growth and used the most moisture at the lower elevation site where temperatures were highest, but timothy and orchardgrass grew best at higher elevations. Timothy contained low levels of nitrogen, phosphorus, and potassium on all sites, whereas tall oatgrass and orchardgrass contained high levels.

  Wheatgrass Establishment with Tillage and Herbicides in a Mesic Medusahead Community

  Young, J. A.; Evans, R. A.; Eckert, R. E. (Society for Range Management, 1969-05-01)

  Intermediate wheatgrass seedlings were successfully established in a medusahead community in 1965, 1966, and 1967 with mechanical or chemical-fallow treatments. Summer fallowing by disk harrowing was the most successful treatment. The most productive wheatgrass stands suppressed but did not eliminate medusahead.

  Use Seeded Ranges in Your Management

  Currie, P. O. (Society for Range Management, 1969-11-01)

  Seeded ranges in conjunction with native range can effectively increase productivity and income from ponderosa pine ranges of Colorado. Average weight of weaned calves was 33 lb higher, and gross income per calf $8.95 larger from combined use of seeded and native range than from native range alone. Cows received better nutrition on seeded ranges, which may increase their lifelong production. Similar benefits can be expected by grazing yearlings. Seeding requires an initial investment of about $8.50 per acre which can be repaid within 3 years as a result of increased grazing capacity. Several grasses are recommended for seeding on the basis of their proven performance to meet specific forage needs.

  Vegetative Response Following Pinyon-Juniper Control in Arizona

  O'Rourke, J. T.; Ogden, P. R. (Society for Range Management, 1969-11-01)

  Mean percentage calcium carbonate levels of near 13% in the surface foot of soil and low pinyon-juniper crown cover (13% and 26%) were associated with no increase in perennial grass herbage production four to five years after pinyon-juniper control in north-central Arizona. Both percentage calcium carbonate in the surface soil and percentage pinyon-juniper crown cover are expressions of the long-time moisture regime of a site and may be good indices for predicting potential understory response which might be expected from pinyon-juniper control.

  Water Control by Rangeland Management

  Biswell, H. H. (Society for Range Management, 1969-07-01)

  In rangeland management, water quantity and quality are related to range condition. The better the range condition, the better the water relationships. Range condition can be improved by regulating grazing, reseeding, fertilizing, type conversions, and contour furrowing and pitting. Rangelands are highly variable in nearly every respect. The range manager must understand the climatic/topographic/soil/plant/animal/water relationships for the areas under his control; he must have sound management objectives; and he must be willing to work toward those objectives in so far as is economically feasible.

  Trick Tanks: Water Developments for Range Livestock

  Pearson, H. A.; Morrison, D. C.; Wolke, W. K. (Society for Range Management, 1969-09-01)

  Trick tanks with large rain collectors may provide water for livestock at half the cost of hauling, with an added benefit of shelter.

  Time of Collection and Storage in Relation to Germination of Desert Saltbush Seed

  Chatterton, N. J.; McKell, C. M. (Society for Range Management, 1969-09-01)

  Seeds of desert saltbush (Atriplex polycarpa) were collected at two locations early and later during the season of seed maturity. The percentage of filled seed was highest in the early collection. Seed that matured early and was collected early germinated more rapidly and to a higher percentage than seed collected when not fully mature. Seeds left to ripen on the plants often germinate while still on the plants.

  The Piosphere: Sheep Track and Dung Patterns

  Lange, R. T. (Society for Range Management, 1969-11-01)

  The basic ecological unit in arid areas under grazing animals is envisaged as a zone round a watering point and is termed the piosphere (from the Greek "pios" = to drink). A piosphere in which sheep tracks can be distinguished in aerial photographs has been investigated; length, direction and type of track are described; remarkable adherance of the tracks to the near radial (significant deviation of 2.5° to left) indicate navigational skill in sheep. Sheep forage but do not cut visible tracks between the radial tracks. Sheep density can be estimated from dung density since pellets of dung persist for long periods in the arid regions. It is suggested that understanding the piosphere will contribute to management in arid rangelands.

  Temperatures of Headfires in the Southern Mixed Prairie of Texas

  Stinson, K. J.; Wright, H. A. (Society for Range Management, 1969-05-01)

  Maximum soil surface temperatures varied from 182 F to 1260 F for fuels that varied from 1546 to 7025 lb/acre Tempil card data correlated well with these data-r = 0.919. The duration of temperatures above 150 F varied from 0.9 to 5.4 minutes. The data from this study can be used to simulate approximate intensities of natural fires with a portable burner. Fires with soil surface temperatures above 1000 F show potential to kill mesquite trees.

  Steer Grazing on Mixed Coniferous Forest Ranges in Northeastern Oregon

  Hedrick, D. W.; Eller, B. R.; McArthur, J. A. B.; Pettit, R. D. (Society for Range Management, 1969-09-01)

  Steers grazing on pinegrass-browse forage in the mixed coniferous forest make good use of these areas in late spring and early summer. Weight gains average about one pound per day for animals wintered at intermediate levels (gaining about one and one quarter pound per day). Cows on the same area in the fall brought the total stocking rate to about three acres per AUM. The best animal performance appears to coincide with maximum vegetative development, but early grazing is essential to fully utilize pinegrass and legumes. Browse is of primary value in the fall for cows from which calves have been weaned.
