Clay transformations following a leaching experiment on an acid brown soil
Detailed studies on soil processes commonly involve the use of reconstructed soil columns (e.g. James & Riha, 1989; Liu et al., 1990; Smith et al., 1995). This approach reduces the inherent variability associated with field experiments, allows the simultaneous monitoring of solution and solid phases, and limits the interactive effects from concomitant processes. Sample pretreatment (airdrying, ...
متن کاملthe potential for direct application of papermill sludge to land: a greenhouse study
papermill sludge (pms) is the waste product from the paper manufacturing industry and is produced in considerable quantities worldwide. this investigation characterised a pms from a papermill plant in south africa and investigated the potential for direct land application of the pms to soil. in a pot experiment, application of pms to three contrasting soils at equivalent rates of 0, 10, 20 and ...
متن کاملEvaluation of leaching potential of oxyfluorfen in clay soil under field conditions
Oxyfluorfen is a selective pre and post emergent herbicide used to control certain annual broadleaf and grassy weeds in vegetables, fruits, cotton, ornamentals and on non-crop areas. It is a contact herbicide and light is required for it to affect target plants (USDA 1990). Oxyfluorfen has a strong tendency to adsorb to soil particles. It is therefore, unlikely to leach downward or to, contamin...
متن کاملLeaching potential of persistent soil fumigant residues.
Persistent fumigant residues in soil resulting from agricultural pest-control practices may be released into water and leached to groundwater. In this study, the leaching potential of persistent soil fumigant residues was evaluated, and the effect of dissolved organic matter (DOM) and ammonium thiosulfate (ATS) amendment was investigated. A silt loam soil was incubated separately with the fumig...
متن کاملapplication 0f sewage sludge ash to improve engineering properties of clay soil in water structures
different additives have been considered to improve stabilization of the engineering properties of fine-grained soil. the present study investigated the effect of the addition of sewage sludge ash on the compressive strength of clay soil at optimum moisture content and under saturated conditions. the four treatments tested were the addition of 0%, 5%, 10% and 15% sewage sludge ash to clayey soi...
