Hydrochemical Definition Of Ground Water And Surface Water, With An Emphasis On The Origin Of The Ground-Water Salinity In Southern Juab Valley, Juab County, Utah, Heidi K. Hadley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
As part of a U.S. Geological Survey study in Juab Valley in central Utah from 1991 to 1994, the chemistry of ground - and surface -water samples was determined. Total dissolved solids in the ground water of southern Juab Valley have historically been higher, in general, than ground water in other areas of Utah. Total dissolved solids for ground-water samples from this study ranged from 623 to 3,980 milligrams/liter. High-sulfate chemical data of previous studies suggested that the major source of ground-water salinity is the dissolution of gypsum (hydrous calcium sulfate ) from the Arapien Shale. Sulfur-34 to sulfur-32 isotopic …
The Effect Of Salinity Level Upon The Yield, Root Growth, And Water Extraction Of Contrasting Rooting Subpopulations Of Alfalfa (Medicago Sativa) Under Conditions Of Zero Leaching, Laura A. Vincent
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A major problem in irrigated agriculture in the Western U.S. is the gradual accumulation of salinity in the plant root zone. These nonuniformly saline soils contain increasing amounts of salinity with depth, and salt accumulation is accelerated in situations where leaching is minimized. Root growth and thus plant yield is limited in these soils due to decreased water uptake. We studied the root growth of two subpopulations of alfalfa differing in their ability to produce fibrous roots to determine if altering root morphology would increase plant yield and water extraction, in an irrigated saline soil.

Salinity Action Plan, Department Of Agriculture And Food, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
In November, the Premier of Western Australia, Richard Court, released his governments strategy to tackle one of the State's most serious environmental problems - salinity. This article provides a summary of the action plan, full details are available in a two volum set 'Salinity - a situation statement for Western Australia' and 'Western australian salinity action plan'.

Soils Of The Weaber Plain, East Kimberley, Western Australia, J C. Dixon
Soils Of The Weaber Plain, East Kimberley, Western Australia, J C. Dixon
Resource management technical reports
The Weaber Plain, north-east of Kununurra, is one of three "black soil" plains in the Kimberley area of Western Australia. It comprises about 15,000 hectares of irrigable land, part of which is known as Stage 2 of the Ord River Irrigation Area (ORIA). The area was surveyed in 1977 following a similar survey of the nearby Keep River Plain and preceding a survey of the Ivanhoe Plain, which has since been developed commercially. Map units and soil series used in those reports have also been used for this rep ility in crop selection, preferring high water use crops.

Degradation Of Remnant Vegetation, Richard George, Don Mcfarlane, Russell Speed
Degradation Of Remnant Vegetation, Richard George, Don Mcfarlane, Russell Speed
Journal of the Department of Agriculture, Western Australia, Series 4
Remnant vegetation, wetlands and riverine systems on both private and public land throughout south-western Australia are being rapidly degraded by dryland salinity, inundation, silting, nutrient enrichment and weed invasion. Richard George, Don McFarlane and Russel Speed outline some of the reasons why this is happening and provide some case studies that highlight actions to protect these remnants.
