A study using GPS and GIS technology to make accurate measurements of the spatial distribution and area coverage of urine depositions in grazed dairy and sheep and beef pastures in New Zealand.

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 ...

This paper examines the effects of two different forms of nitrogen (N) fertiliser, urea and ammonium sulphate nitrate (ASN) on the production and quality of spray irrigated dairy pastures in Canterbury. Pasture production ...

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 ...
