Seasonal, Diurnal And Species Variation In Forage Moisture Content In Relation To Site On Mountain Summer Range Of Northern Utah, Chaudhry Mohammad Sharif

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Practical assessments of range production and utilization are based on forage weight estimates. In preparing these estimates moisture content in green vegetation offers some problems. The moisture component is not likely to be constant for a given species. Diurnal, seasonal and site variability have been well illustrated for agronomic and tree species (Salisbury, 1848; Jenkins, 1879; Miller, 1917; Pearson, 1924; Watkins, 1940; Parker, 1951; Ackley, 1954; Werner, 1954; Zohary and Orshan, 1956; Slatyer, 1959; Kozlowaki, 1965 and Jame son, 1966). Since variability is also likely for range plants, computations made on green weights are apt to be fallacious. It is …

Soil Moisture Depletion By Quaking Aspen And Gambel Oak In Central Utah, Jere J. Christner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil moisture depletion was studied in quaking aspen and Gambel oak areas of central Utah. The study area is located at about 8100 feet elevation in a zone with 20 to 25 inches precipitation annually.

Treatments ranged from no disturbance to clearcutting. Soil Moisture was measured periodically during the summer of 1966.

Results showed less soil moisture depletion on the plots of least residual basel area. Average soil moisture depletion the season following cutting at two sites was 4.3 inches less than it was on higher residual basal area plots.

The reduction in soil moisture depletion occurred principally below the …
