Yield Response to Time of Burning in the Kansas Flint HillsThe effect of time of spring burning on herbage yields in pastures grazed throughout the growing season was investigated. Early and mid-spring burning reduced forage yields but late-spring burning caused no reduction. Weed yield was significantly reduced by late-spring burning. Differences in grazing distribution apparently affected treatment responses in ordinary upland and limestone breaks range sites.

Yield and Mineral Composition of Grass Species Grown on Acid Grassland SoilsThe objective was to study the use of various grass species, two liming materials, and phosphorus as means of improving very acid, unproductive, grassland soils. Phosphorus applications increased yields of all 10 species at all levels of liming. Liming with a mixture of calcic and magnesium limes increased yield more than either alone. The outstanding performance of veldtgrass was associated with its calcium-foraging ability, which resulted in the highest tissue concentrations of calcium. These guidelines point toward the use of phosphorus and small amounts of limestone, containing both Ca and Mg, with calcium-foraging species for successful forage establishment in acid grassland soils.

Voles Damage Big Sagebrush in Southwestern MontanaExtensive destruction of big sagebrush in southwestern Montana in the winter of 1963-64 is attributed to a sudden irruption of the population of voles. Such extensive sudden destruction of browse species over wide areas concerns both ranchers and game managers because it can affect production of browse and forage for several succeeding years.

Viability of Grass Seed After Long Uncontrolled StorageIn 1961, germination tests were made on seeds of 12 southwestern grass species collected between 1933 and 1939. Some seeds of vine-mesquite, silver beardgrass, curlymesquite, and Arizona cottontop remained viable, even though stored with no control of humidity or temperature.

Vegetation and Soils of No Man's Land Mesa Relict Area, UtahOn No Man's Land Mesa, a relict area in Kane County, Utah, two distinctly different soils were found which produce significantly different kinds and amounts of vegetation. The Upland sand (Pinon-Juniper) site yielded an average of about 1100 lb/acre airdry comprising 10% grass, 5% forbs and 85% trees and shrubs. The Upland shallow breaks (Pinon-Juniper) site yielded an average of nearly 800 lb/acre comprising 5% grass, 5% forbs and 90% trees and shrubs.

Thickening and Spread of Crested Wheatgrass Stands on Southern Idaho RangesCrested and fairway wheatgrass stands thickened and plants spread to adjacent areas from 1954 to 1966 on six experimental areas in southern Idaho. Drilling produced 10 times more seedlings than broadcasting, and stands reached full production much sooner. Plant survival and final numbers were greatest on the plowed, burned, and untreated seedbeds, in that order.

The South Needs Range MenForest range is an important source of forage for the big and growing business of livestock production in the South. People trained in management of southern ranges are needed for effective utilization of the South's grazing resource but the supply is too limited. The South needs a range curriculum.

The Relationship of Tree Overstory and Herbaceous Understory VegetationFor study of the effect of trees on understory vegetation a good mathematical equation is very helpful. This article presents an equation which fits overstory-understory data better than previously used equations.

The Range Society is at the CrossroadsThe American Society of Range Management has come far in its first 20 years, as the sole professional organization with conservation of rangelands as its dominant objective. But in the meantime, urbanization and increased leisure for more people have changed our environment. The Range Society should accept broader professional concern for all matters pertaining to range in tomorrow's environment. We need to assemble facts and establish strong policy regarding conservation and use of rangelands. Finally we need closer ties with user groups and other professional natural resource organizations-to carry out our objectives.

The Monarch Big Sagebrush of White MountainAn unusually massive big sagebrush plant has been discovered growing in the White Mountains in eastern California. This plant is almost 15 ft tall, has an average crown spread of 11 ft, and its main trunk is 48 inches in circumference at ground level. The aggregate value of this monarch shrub is 65.4.

The General Environment of The SouthThe best laid plans often fail if human (socio-cultural) factors are not taken into account. Certain socio-cultural factors, particularly those which are significant in the emerging mass society, are indicated in the following sketch of the general environment of the South. Changes are occurring in the region that are certain to have direct bearing upon the social and economic situation in which the stockman will carry on his activities. Furthermore, a new kind of agricultural operation is emerging and with it a new type of agricultural man-the farm businessman.

Supplemental Protein Levels for Calves and Yearlings Grazing on Winter Bluestem PastureOne lb/head daily of soybean oil meal pellets was adequate supplemental protein for yearling steers grazing winter bluestem pasture when followed by summer grazing that permitted the steers to compensate for low winter gains. Calves responded to additional supplemental feed, energy or protein with efficient gains.

Subterranean Clover Versus Nitrogen Fertilized Annual Grasslands: Botanical Composition and Protein ContentApplication of N increased the percentage grass and depressed annual legumes. Subterranean clover not N fertilized was very competitive with grass when the sward was grazed or mowed. The establishment of subterranean clover resulted in higher protein forage when need was greatest during the dry season, compared with N fertilization which depressed protein levels during the same period.

Seeding Sherman Big BluegrassSherman big bluegrass was successfully established by planting into summer-fallowed land with a double-disc, depth-band drill to control seeding depth at 5/8-inch. Planting during July and August into a moist seedbed gave optimum seedling establishment. Weed competition and erosion on the summer-fallowed land was reduced by leaving the ground in rough-plowed condition until immediately before seeding.
