Ecology of Coleophora spissicornis (Haworth) and C. frischella (Linnaeus) associated with Trifolium repens Linnaeus in Canterbury, New Zealand
(Lincoln College, University of Canterbury, 1975)
This thesis reports the first comprehensive ecological study on a population of Coleophora spissicornis and C. frischella infesting Trifolium repens. The study was conducted at Lincoln, New Zealand during the summer seasons ...
A laboratory study of bacteria-facilitated cadmium transport in alluvial gravel aquifer media
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2005)
Colloids, including bacteria, can dramatically accelerate the transport of heavy metals in ground water. Batch and column experiments were conducted to investigate adsorption of cadmium (Cd) onto Bacillus subtilis spores ...
Fractionation of arsenic in soil by a continuous-flow sequential extraction method
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2001)
Batch sequential extraction techniques for fractionating metals or metalloids in soils are time consuming and subject to several potential errors. The development of a continuous-flow sequential extraction method for soil ...
Fractionation of copper, nickel, and zinc in metal-spiked sewage sludge
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2001)
The enrichment or spiking of sewage sludge with heavy metals for experimental purposes is a fairly widely used, although sometimes controversial, technique. A study was undertaken, using a sequential fractionation scheme, ...
