Long-Term Effects Of Tillage On The Retention And Transport Of Soil Water, H. D. Scott, L. S. Wood, W. M. Miley Jun 1986

Long-Term Effects Of Tillage On The Retention And Transport Of Soil Water, H. D. Scott, L. S. Wood, W. M. Miley

Technical Reports

Quantitative measurements were made of the physical and chemical properties of two virgin prairie soils, Crowley and Jay, that remain in their native Arkansas environments and of similar soils that had been tilled extensively. Comparisons were made of soil properties at several depths. When compared with the tilled soils the virgin soils had higher organic matter contents, saturated hydraulic conductivities and water retained at several applied pressures. Bulk densities and hydraulic resistances were lower in the virgin soils. For the Crowley silt loam, values of pH and elemental contents of the virgin soil were higher than those of the tilled …

Algal Growth Potentials And Heavy Metal Concentrations Of The Primary Streams To Upper Beaver Lake, Richard L. Meyer, W. Reed Green, Kenneth F. Steele, Diana Wickliff Jun 1986

Algal Growth Potentials And Heavy Metal Concentrations Of The Primary Streams To Upper Beaver Lake, Richard L. Meyer, W. Reed Green, Kenneth F. Steele, Diana Wickliff

Technical Reports

Meyer and Green (1984) demonstrated the probable inhibition of algal growth potential by heavy metals in upper Beaver Lake. Upper Beaver Lake receives water from three tributaries. One contains a small reservoir and the combined streams receive sewage input. Collections were made approximately monthly at eight sites for the Algal Assay Bottle Test (AABT) and heavy metal analysis. In general, AABT results indicated that the collections above the sewage lnput were phosphorus limited while those below were nitrogen or combined nitrogen and phosphorus limited. Growth inhibition occurred during summer and early fall at various sites with greater inhibition at the …

Local Water Resource Information Management System, David G. Parker, Sandra C. Parker Jun 1986

Local Water Resource Information Management System, David G. Parker, Sandra C. Parker

Technical Reports

A Beaver Lake water quality database has been designed as a relational database. It has been implemented using software called R:base 5000, a system available for microcomputers using MS- or PC- DOS operating systems. The data in the database include that concerned with the author(s), title, date of publication, agency doing the study, agency funding the study and complete reference for the document. Other aspects of the database are designed to allow retrievals based on any author, study dates, parameters measured and keywords.

Evaluation Of Packed Towers For Removing Volatile Organics From Surface Waters, James W. Moore Jun 1986

Evaluation Of Packed Towers For Removing Volatile Organics From Surface Waters, James W. Moore

Technical Reports

This study analyzes the potential of packed tower aeration as a remedial treatment process for the removal of trace organics on either an acute or chronic basis. Both pilot-scale installations of the packed tower process were reviewed. Included are basic modeling considerations for the removal of volatile trace organics from raw water. Included also is an assessment of the state of the technology as applied to air stripping of water.

Qualitative And Quantitative Aquatic Algal Data Compilation To Determine Macrotrends- Ii, Richard L. Meyer Jun 1986

Qualitative And Quantitative Aquatic Algal Data Compilation To Determine Macrotrends- Ii, Richard L. Meyer

Technical Reports

A database of the algae of Arkansas has been established by the use of a relational database management system (dBase III). The system was chosen to be readily available for microcomputers using MS and PC-DOS. The database contains taxonomic fields from division through variety, synonomy, authors, starting date and definitive descriptive source. The data is cross-referenced by ecoregion, community and subcommunity. The database contains nearly 1,500 taxonomic records in all division and classes of freshwater algae. These data are sortable by any of the included parameters. The data have been used to initiate the publication of the algal flora of …

The Behavior Of Soluble Salt In Sharkey Clay- Ii, J. T. Gilmour, R. E. Baser, H. D. Scott, J. A. Ferguson Jun 1986

The Behavior Of Soluble Salt In Sharkey Clay- Ii, J. T. Gilmour, R. E. Baser, H. D. Scott, J. A. Ferguson

Technical Reports

Soluble salts have been shown to accumulate in Arkansas soils in sufficient quantities to impair crop plant growth. The major objective of this study was to describe the behavior of soluble chloride salt over long time periods in Sharkey clay - a major Mississippi Delta soil. Prior to flooding rice, leaching of chloride in response to rainfall was observed. The inclusion of a sandy subsoil layer reduced this effect presumably by limiting downward movement of water under unsaturated conditions. No lateral movement of the chloride salt was found during the period prior to flooding. Removal of soluble chloride salts from …
