Evaluation Of Additives With Bracken Herbicides Applied To Boomsprayer., R. Madin, J. Buckley

Experimental Summaries - Plant Research

Treatments were applied in December 1987. Height of the Bracken made application by boom difficult due to inability to adequately raise the boom to give clearance. Some brushing of the Bracken with the boom was unavoidable. Assessment of the trial will be made in March 1988.

Effects Of Residue Levels Of Glean On Lupin Growth, And Possible Synergism By Hoegrass., Terry Piper, Patrick Pigott

Experimental Summaries - Plant Research

Trial 87PE37

This trial was conducted to confirm the results of 86WH53 and 87WH64. The trial commenced in September and in a glasshouse thus temperatures were higher and growth faster then in the field trials.
There are no significant effects of soil applied Glean or Hoegrass, and no interaction between the two herbicides.
In contrast, there is a very significant stunting of plants by Glean applied post emergence if Hoegrass is co-applied, but not by Glean alone.

Lithologic Controls On Karst Groundwater Flow, Lost River Groundwater Basin, Warren County, Kentucky, Christopher Groves

Masters Theses & Specialist Projects

The Lost River Groundwater Drainage Basin in Warren County, Kentucky, is a karst drainage system encompassing 55 square miles (143 square kilometers) developed within the Mississippian St. Louis and Ste. Genevieve Limestones. Near the contact between these two formations are two bedded chert units, the Lost River Chert Bed (Elrod, 1899) within the Ste. Genevieve and the Corydon Chert Member (Woodson, 1983) of the St. Louis, which appear to be perching layers to shallow karst groundwater flow. Groundwater may be seen flowing on top of these beds in various cave streams and at swallets and springs throughout the basin.

Baseline Acidity Of Percipitation At The South Pole During The Last Two Millennia, J H. Cragin, M B. Giovinetto, A J. Gow

United States Army: Publications

Measurements of meltwater pH from annual layers of South Pole firn and ice samples ranging in age from 40 to 2000 years B .P. show that precipitation at this remote site has a higher natural acidity than that expected from atmospheric equilibrium with CO2. The average pH of deaerated (C O2-free)samples was 5 .64 + 0.08, while a irequilibrated samples averaged5 .37 + 0.08, a pH that is about a factor of two more acidic than the expected background pH of 5.65. The observed" excess" acidity can be accounted for by SO1-and NO7 levels in the samples originating from non-anthropogenic …

Soluble Sugar Concentrations In Needles And Bark Of Western White Pine In Response To Season And Blister Rust, United States Department Of Agriculture, Forest Service

Forestry

Amounts of soluble sugars in certain tissues of 12- to 16-year-old western white pine (Pinus monticola Dougl.) trees, each with a blister rust canker girdling about 50 percent of the bole circumference, were compared with rust-free trees. Fructose, glucose, sucrose, raffinose, and stachyose extracted from needles and healthy and diseased bark were identified with thin-layer chromatography and quantified with a densitometer. The host's seasonal growth cycle induced changes in sugar concentrations in current, 1- and 2-year needles, but the bole cankers did not. Amounts of bark sugars characterized the activities of the rust fungus (Cronartium ribicola J.C. Fisch.) as well …

The Demography Of Doublegee. Ecological Studies On Arum Lily., F. D. Panetta

Experimental Summaries - Plant Research

3.1 Growth of doublegees under summer irrigation. (87A40)

The weevil, Perapion antiquum is a potential biological control agent of doublegee. However, it exhibits large population crashes during the summer months in the summer-dry areas of the Western Caped of South Africa, where it is native. It has been suggested that one means of successfully establishing Perapion in Western Australia could be to maintain populations in 'oases' over the summer months. The aim of this experiment was to determine how readily doublegee could be maintained in a non-senescent phase under irrigated and shaded conditions.

Container-Grown Ponderosa Pine Seedlings Outperform Bareroot Seedlings On Harsh Sites In Southern Utah, United States Department Of Agriculture, Forest Service

Forestry

Reforestation of ponderosa pine (Pinus ponderosa Dougl. ex Laws.) on the lower elevations of the Dixie National Forest in southern Utah has traditionally been challenging. Replanting has often been necessary, costly, and not always successful. Although this problem is not unique, the low levels of available soil moisture during the spring planting season are probably as critical in the Dixie as anywhere in the Intermountain Region. Until this study was initiated, only bareroot seedlings had been planted.

Overstory Removal And Residue Treatments Affect Soil Surface, Air, And Soil Temperature: Implications For Seedling Survival, United States Department Of Agriculture, Forest Service

Forestry

Timber harvesting and residue reduction practices that alter shade, surface thermal properties, and moisture influence energy balance and heat transfer on the site, significantly influencing temperatures. Because the problems of mortality to seedlings due to high temperature and insufficient moisture are potentially widespread and expensive, it is crucial to be able to identify problem sites during the planning process.

Estimation Of Runoff Volumes For Ungauged Catchments In The Agricultural Areas Of Western Australia, J R. Davies, D J. Mcfarlane

Resource management technical reports

Describes an analysis of flood runoff volumes from 16 small, gauged catchments in the agricultural areas of south western Australia. It also describes methods for estimating flood runoff volumes from ungauged catchments. The independent variables found to be statistically significant in explaining the variability in flood runoff volumes from the gauged catchments were catchment area, mean annual rainfall and the percentage of the catchment that was cleared. No soil factor was found to be significant.

Finding The Appropriate Forage Value For Analyzing The Feasibility Of Public Range Improvements, United States Department Of Agriculture, Forest Service

Range Management Plans (UT)

To complete economic analysis of range improvements completed on the Oak Creek Management area of central Utah, we needed an estimate of the value of forage. A review of the literature revealed several methods of estimating forage values. These methods yielded eight estimates of public rangeland forage ranging from $1.23 to $30 per animal unit month (AUM). Six of the estimates were based on actual market transactions or current administered prices and were the most reflective of actual economic processes. The best estimates of value were those for leasing similar rangeland in the immediate area.

Investigation Of A Saline Valley On Allandale Research Farm, D J. Mcfarlane, R Engel, A T. Ryder

Resource management technical reports

Geophysical surveys and drilling were used to investigate a saline valley on Allandale Research Farm. These techniques showed that the geology is controlling the location of two main areas of saline seeps and they identified another area at risk of increased salinity. They were also used to obtain information on the groundwater system and to assist in making management recommendations.

Electromagnetic terrain conductivity surveys showed that the most saline soils occurred upstream of a cross-cutting magnetic anomaly caused by a dolerite dyke. A seismic survey showed that the anomaly coincided with a bedrock rise. This bedrock rise restricts groundwater flow …
