Spatial and seasonal distribution of rainfall erosivity in Australia.
November 1, 2002... Introduction Erosion risk assessment is required for land management and conservation planning. The most commonly used method for predicting the average soil loss rate at large-scale remains the universal soil loss equation (USLE,...

Interpretation of morphological features in a salt-affected duplex soil toposequence with an altered soil water regime in western Victoria.
November 1, 2002... Introduction Waterlogging or saturation of topsoils is a major constraint to agricultural production in southern Australia. So is dryland salinity. To understand the occurrence and driving mechanisms of seasonal waterlogging and salinity,...

Restricting layers, flow paths, and correlation between duration of soil saturation and soil morphological features along a hillslope with an altered soil water regime in western Victoria.
November 1, 2002... Introduction Waterlogging or saturation of topsoils is a major constraint to agricultural production in southern Australia (e.g. McFarlane and Cox 1992; Cox et al. 1996; Fitzpatrick et al. 1996). Soil saturation ,is often associated with...

Soil erosion rates under intensive vegetable production on clay loam, strongly structured soils at Pukekohe, New Zealand.
November 1, 2002... Introduction Vegetable production is a very intensive land use, especially where it is practised as a continuous monoculture. It is characterised by frequent tillage using a wide variety of implements, the use of heavy high-powered...

Effect of cattle treading on interrill erosion from hill pasture: modelling concepts and analysis of rainfall simulator data.
November 1, 2002... Introduction Intensive winter grazing by cattle on hillslope pasture damages vegetation and soil, thereby increasing sediment and nutrient loads (Sharpley and Syers 1976; Lambert et al. 1985; Cooke 1988). There is a trend in New Zealand...

Lignin, carbohydrate, and amino sugar distribution and transformation in the tropical highland soils of northern Thailand under cabbage cultivation, Pinus reforestation, secondary forest, and primary forest.
November 1, 2002... Introduction Soil organic matter (SOM) encompasses plant, animal, and microbial residues in all stages of decomposition and it is often closely associated with inorganic soil components. The cycling of SOM is strongly dependent on the...

Subsoil bulk density and organic carbon stock in relation to land use for a Western Australian Sodosol.
November 1, 2002... Introduction The bulk density of clay soils can differ widely depending on clay content, the packing of elementary clay particles (Bruand and Tessier 2000), and water content (Fredlund and Rahardjo 1993; Voltz and Cabidoche 1995). In the...

Soil nitrogen availability predictor (SNAP): a simple model for predicting mineralisation of nitrogen in forest soils.
November 1, 2002... Introduction There is much evidence in Australia that, together with water and P availability, N availability is one of the main factors limiting forest production. It is important to be able to predict the extent to which N is limiting at...

Loss of mass and nitrogen from biosolids applied to a pine plantation.
November 1, 2002... Introduction Land application of biosolids has received increased attention throughout the world in the last 2 decades. Biosolids contains many nutrients beneficial to plant growth, particularly nitrogen (N) and phosphorus (P). The use of...

Applying biosolids to acid soils in New South Wales: are guideline soil metal limits from other countries appropriate?
November 1, 2002... Introduction The use of biosolids as an agricultural fertiliser and soil conditioner is now widely accepted in many parts of the world, especially in Europe and the United States (Garvey et al. 1993). It has the advantage of returning...

Sulfide oxidation and acidification of acid sulfate soil materials treated with CaC[O.sub.3] and seawater-neutralised bauxite refinery residue.
November 1, 2002... Introduction The presence of acid sulfate soils (ASS) is a major constraint on land use and development in coastal areas of Australia (White and Melville 1996). ASS contain iron sulfides (principally pyrite) or the products of sulfide...
