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 ...

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, ...

Feed shortages occur in spring because the rate of pasture growth is below the cow demand. Spring pasture growth rate is slow in the South Island because the soil temperature is low and the rate of nitrogen (N) supply from ...

Lincoln University and Ravensdown Fertiliser Co-operative have developed a new soil treatment technology, called 'eco-n' technology, that can reduce the environmental impacts of dairy farming and at the same time help ...

Although phosphate phosphorus (P) is strongly sorbed in many soils, it may be quickly transported through the soil by preferential flow. Under flood irrigation, preferential flow is especially pronounced and associated ...

This study was conducted to improve the ability of indigenous New Zealand white-rot fungi to remove pentachlorophenol (PCP) from contaminated field soil. The effects of different bioaugmentation conditions on PCP removal ...

This study was conducted to improve the pentachlorophenol (PCP) bioremediation ability of white-rot fungi in highly contaminated field soils by manipulating bioaugmentation variables. These were the dry weight percentage ...

Phosphorus losses from soils have been reported to impair the water quality, resulting in deaths of fish and other marine animals, and can harm human health. The objective of this study was to determine the seasonal ...

The recent report by the New Zealand Parliamentary Commissioner for the Environment, called "Growing for Good", highlighted the adverse impacts that nitrate leaching can have on water quality. It called for a 'redesigning ...

The decline in water quality in Lake Taupo has been attributed to nitrogen (N) leaching from surrounding land areas. Pastoral agriculture has been identified as a significant contributor to this N transfer to the lake ...
