Effect Of Bmp Implementation On Storm Flow Quality Of Two Northwestern Arkansas Streams, Dwayne R. Edwards, Tommy C. Daniel, H. Don Scott, Phillip A. Moore Jr., John F. Murdoch, Paul F. Vendrell Sep 1997

Effect Of Bmp Implementation On Storm Flow Quality Of Two Northwestern Arkansas Streams, Dwayne R. Edwards, Tommy C. Daniel, H. Don Scott, Phillip A. Moore Jr., John F. Murdoch, Paul F. Vendrell

Biosystems and Agricultural Engineering Faculty Publications

The effectiveness of management practices in improving quality of runoff from agricultural land areas has been reported based primarily on results from plot- and field-scale studies. There is limited information available on watershed scales, particularly when the dominant agricultural land use is pasture. The objective of this study was to determine whether a program of Best Management Practice (BMP) implementation in the Lincoln Lake watershed of northwestern Arkansas was effective in reducing storm stream flow concentrations and mass transport of nitrate nitrogen (NO3-N), ammonia nitrogen (NH3-N), total Kjeldahl nitrogen (TKN), ortho-phosphorus (PO4-P), total phosphorus …

Native Vegetation On Farms Survey 1996 : A Survey Of Farmers Attitudes To Native Vegetation And Landcare In The Wheatbelt Of Western Australia, Suzanne Jenkins May 1997

Native Vegetation On Farms Survey 1996 : A Survey Of Farmers Attitudes To Native Vegetation And Landcare In The Wheatbelt Of Western Australia, Suzanne Jenkins

Resource management technical reports

The Native Vegetation on Farms survey 1996 was performed to assess the attitudes of farmers to a number of issues related to existing native vegetation on farmland, the replanting of vegetation on farms and land degradation. Research has shown that it is important for a proportion of all farmland to have some native vegetation for ecological stability, to regulate hydrological processes and for long-term sustainability of farm production.

Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard May 1997

Evaluation Of Continuous Flow Constructed Wetlands Treating Swine Waste, Stephanie Rivard

Masters Theses & Specialist Projects

The ability for wetlands to purify contaminated water is not a new concept. Natural wetlands have been cleansing water within our environment for ages. After studying the process of natural wetlands the same concept was applied to municipal waste. It is the success of constructed wetlands treating municipal waste that created the new idea for the application of a wetland system to treat wastewater from livestock facilities. Through proper design and management, constructed wetlands may be useful for reducing the nutrient concentration of waste (Rieck el al., 1996). Taking into consideration the higher nutrient loads of livestock waste, the same …

Vegetative Filter Strip Removal Of Metals In Runoff From Poultry Litter-Amended Fescuegrass Plots, Dwayne R. Edwards, P. A. Moore Jr., Tommy C. Daniel, Puneet Srivastava, D. J. Nichols Jan 1997

Vegetative Filter Strip Removal Of Metals In Runoff From Poultry Litter-Amended Fescuegrass Plots, Dwayne R. Edwards, P. A. Moore Jr., Tommy C. Daniel, Puneet Srivastava, D. J. Nichols

Biosystems and Agricultural Engineering Faculty Publications

Runoff from land areas amended with poultry (Gallus gallus domesticus) manure can contain elevated concentrations of metals such as Cu, Fe, and Zn. Vegetative filter strips (VFS) can reduce runoff concentrations of animal manure components, but reported studies have typically focused on nutrients and solids rather than metals. This experiment assessed the impact of VFS length (0 to 12 m) on concentrations and mass losses of Cu, Fe, K, Na, Ni, and Zn in runoff from fescuegrass (Festuca arundinacea Schreb.) plots (1.5 m wide × 6 and 12 m long) treated with poultry litter. The runoff was produced from simulated …

Indicator Bacteria Concentrations Of Two Northwest Arkansas Streams In Relation To Flow And Season, Dwayne R. Edwards, Mark S. Coyne, Tommy C. Daniel, P. F. Vendrell, J. F. Murdoch, P. A. Moore Jr. Jan 1997

Indicator Bacteria Concentrations Of Two Northwest Arkansas Streams In Relation To Flow And Season, Dwayne R. Edwards, Mark S. Coyne, Tommy C. Daniel, P. F. Vendrell, J. F. Murdoch, P. A. Moore Jr.

Biosystems and Agricultural Engineering Faculty Publications

Concentrations of indicator bacteria such as fecal coliform (FC) and fecal streptococcus (FS) are often used to assess the suitability of waters for their intended use(s) and to allocate resources for water quality improvement measures. There is evidence, however, that concentrations of FC and FS can be influenced by variables such as season and flow rate during sampling, which could lead to biased results. The objective of this study was to assess the impacts of season and flow rate on concentrations of FC and FS. Fecal indicator bacteria concentrations were measured for approximately three years at five sites on two …

Future Horizons: Recent Literature In Sustainable Agriculture, Gabriel Hegyes, Charles A. Francis Jan 1997

Future Horizons: Recent Literature In Sustainable Agriculture, Gabriel Hegyes, Charles A. Francis

CARI Extension and Education Materials for Sustainable Agriculture

Here is one building block in the foundation for a future agriculture. Increasing trainer literacy in sustainable agriculture can be defined on several levels. At its most literal, it is an anthology of reviews familiarizing the reader with some of the authors, topics, and titles that have composed the sustainable agriculture literature over the last decade or more. It also serves as an annotated bibliography where the dry abstracts of many such works are replaced with insightful essays. Most importantly, this primer is a language text, exposing the user to the semantics, symbols, and syntax of sustainable agriculture. This collection …

Soil Assessment Of The West Gingin Area, Henry Smolinski, G G. Scholz Jan 1997

Soil Assessment Of The West Gingin Area, Henry Smolinski, G G. Scholz

Land resources series

Soils of approximately 80,000 hectares in the West Gingin area, 100 km north of Perth, were surveyed from 1987 to 1989. The area lies on the Swan Coastal Plain within the Gingin Shire. The soils were mapped by the free survey method at a scale of 1:50,000. Thirty-five major soil associations and complexes were identified. These soils have been formed from various parent materials in a a range of depositional environments. Siliceous sand and sodic soils formed in alluvial-lacustrine sediments predominate. The main soils were sampled for chemical and physical analysis and their morphological, chemical and physical properties are discussed …

Soil Information Sheets For The Northern Agricultural Areas, Natural Resources Assessment Group, Agriculture Western Australia, Landcare Western Australia Jan 1997

Soil Information Sheets For The Northern Agricultural Areas, Natural Resources Assessment Group, Agriculture Western Australia, Landcare Western Australia

Agriculture reports

These soil information sheets are produced for farmers in the Northern Wheatbelt. Each sheet summaries information on the particular soil's characteristic properties and associated land use suitability and management. A photograph of a representative profile is provided for each soil. Technical terms are defined in the glossary. Information is presented under the following headings: Soil series and group, occurrence, native vegetation, soil profile description, characteristic soil properties, soil classification (Australian Soil Classification and Northcote Principal Profile Form).

The Salinity And Hydrology Of The Tambellup Townsite And Jam Creek Catchment, R Ferdowsian, A T. Ryder Jan 1997

The Salinity And Hydrology Of The Tambellup Townsite And Jam Creek Catchment, R Ferdowsian, A T. Ryder

Resource management technical reports

The study area covers the Tambellup Town and the Jam Creek Catchment (top photograph on cover). The Tambellup Town is located 115 km north of Albany. The town has a population of 360 people (800 in the whole Shire). Tambellup is experiencing increasing salinity problems. Saline groundwater levels are close to the soil surface and cause deterioration of buildings, roads, infrastructure, death of trees and scalding of land including the sporting grounds. Many hectares of land in the Jam Creek Catchment has become salt-affected and salinity is on increase. The objective of this study was to define the present salinity …
