Modeling environmental impact of unfired bricks in India
… estimate these impacts. The depth of soil extraction has a significantly affects the land use required for bricks; changing this depth in practice or through regulation has the potential to reduce environmental impact without affecting brick performance. The impact of unfired bricks …

Take-all in Wheat: PCR Identification of the Pathogen and the Interactions Amongst Potential Biological Control Agents
… are to detect the fungus in infested plants and soil, and to predict effective combinations of bacteria as biological control agents. Detection was based on avenacinase-based primers and polymerase chain reaction (PCR) conditions specified by earlier research. PCR conditions were modified to …

Pressurized Hot Water and DTPA-Sorbitol, Viable Alternatives for Soil Boron Extraction
… water and DTPA-Sorbitol are two relatively new soil boron (B) extraction methods with potential to replace the cumbersome hot water extraction. The objective of this research is to produce data in support of acceptance or rejection of these two alternative B extractions. The three soil tests …

Extraction, transport, and transformation of poly- and perfluoroalkyl substances in soils impacted by aqueous film-forming foam
… The first research objective was to develop a soil extraction method to enhance the recovery of all PFASs. The second research objective was to conduct a comprehensive site characterization via high spatial resolution sampling of soil and groundwater samples with estimated concentrations of all …

Effect of geochemical processes and environment on the spatial pattern of selenium in soil, surface water, and groundwater at the Hovland Ranch, central South Dakota
… as that may relate to selenium geochemistry in soil and water system at the Hovland Ranch, Haakon County, South Dakota. Representative samples were collected from soil, water, and soil moisture in the field. Preparation of samples and chemical analysis were done in the Water Quality Laboratory, …

Chelate Assisted, Pressurized, Liquid Extraction for the Removal of Adsorbed Metal Contaminants From Soils
Chelate Assisted, Pressurized, Liquid Extraction (CAPLE) has been developed in our laboratory as an efficient, separation-based, extraction methodology for heavy metals in soils. Unlike current extraction methods used in environmental determination of contaminated soils, CAPLE is able to …

Pressurized Hot Water: An Alternative Method of Nutrient Extraction and Subsequent Analysis for Use in Small-Scale Agriculture
Soil analysis for small acreage farms in developing countries is often inconvenient and prohibitively expensive using current procedures, yet the information gained from these soil tests could have economical and environmental benefits. The pressurized hot-water (PHW) extraction coupled with …

Use of stable isotopes to assess phytoremediation of soils contaminated with cadmium and zinc.
… expensive (e. g. removal and disposal of the soil, covering the soil with uncontaminated soil, extraction with acids or chelates) whilst others provide only short term solutions (e. g. reduction of metal bioavailability by liming or adding organic matter). An alternative approach is the use of …
