Management And Pest Management Considerations On Droughty Soils: Four Year Results, David Kulhavy, Kenneth G. Watterson, James Kroll, James R. Meeker Jan 1987

Management And Pest Management Considerations On Droughty Soils: Four Year Results, David Kulhavy, Kenneth G. Watterson, James Kroll, James R. Meeker

Four year survival of pines on droughty (Typic Quartzips~mments) soils was best for longleaf pine and Terr-Sorb -treated loblolly pine. Pest considerations include town ants and Nantucket pine tip moths on loblolly pine. Untreated loblolly pine had reduced leader and total height growth anH increased tip moth infestations, compared to Terra-Sorb and clay-slurry treated loblolly pine. Soil texture averaged less than eight percent silt and clay combined in the treatment areas.

Three species of pines (loblolly, slash and longleaf) were planted with four treatments (loblolly and slash = bareroot, clay dip slurry and TerrasorH ; longleaf = containerized) to test survival on droughty, typic quartzipsamments soils. At the end of the first season, survival~s significantly better for the containerized longleaf and Terrasoro treated loblolly pine (81 and 85%) followed by untreaRed loblolly pine (51%), clay-treated loblolly (50%), then Terrasorb treated slash (48%), untreated slash (41%) and clay-treated slash (36%). At the e~of the second growing season, longleaf had 56% survival, Terrasor~ treated loblolly (51%), clay-dip slurry loblolly (31.9%), Terrasoro treated slash …

The Ecology Of Agropyron Inerme On Protected And Heavily Grazed Range Land In Cache Valley, Utah, Wallace R. Hanson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past decade much attention has been attracted to the great range lands of the West. The inherently low productivity of these arid lands coupled with abnormal drought and constantly heavy use by livestock because of lack of grazing control, have caused these lands to become greatly depleted over most of the West. That the vegetation on most range land in the intermountain states is depleted appreciably is evident to the careful observer. Undoubtedly the vegetation of much of the range has decreased in quantity, but more serious in many cases is the decrease in quality. Valuable forage species …
