Process, performance, and pollution potential: a review of septic tank-soil absorption systems.
December 1, 2005... Introduction On-site wastewater treatment and dispersal systems (OWTS) are used in non-sewered populated areas in 20% of Australian households to treat and dispose of household wastewater. The most common OWTS in Australia is the septic...

Managing soils to enhance the potential for bioremediation of water repellency.
December 1, 2005... Introduction Water repellency, associated mostly with siliceous sands, occurs on more than 5 million hectares of western and southern Australia (Tate et al. 1989). Repellency causes uneven infiltration of water into soil resulting in poor...

Mapping boron deficiency risk in soils of south-west Western Australia using a weight of evidence model.
December 1, 2005... Introduction Soils across much of the south-west of Western Australia (WA) were formed from highly weathered parent materials and are low in many essential plant nutrients (Churchward 1986; McArthur 1991; Moore 1998). Deficiencies of...

Agricultural soils irrigated with acidic mine water: acidity, heavy metals, and crop contamination.
December 1, 2005... Introduction Acid mine drainage (AMD) is a major environmental threat to the surroundings of sulfidic mine sites (Evangelou 1998; Williams 2001; Lin and Lin 2003). Much attention has been paid to the degradation of the downstream aquatic...

Colour variation in standard soil-colour charts.
December 1, 2005... Introduction Colour is a distinctive feature of soil. Early efforts to set soil-colour standards and terms for field use followed the tradition of naturalists, who since the 17th Century used colour charts to describe plants and animals...

Lateritic soils of Kerala, India: their mineralogy, genesis, and taxonomy.
December 1, 2005... Introduction The acid ferruginous soils of Kerala State, southern India, are often referred to as 'lateritc' and/or 'lateritic soils' and have attracted the attention of earth scientists all over the world because of their importance in...

The effectiveness of coal fly-ash to decrease phosphorus loss from grassland soils.
December 1, 2005... Introduction Phosphorus (P) loss from soils to surface waters is recognised as a key factor in accelerated eutrophication, causing poor water quality. Mitigation of P loss has centered on management strategies such as balancing farm inputs...

Atrazine degradation in soils: the role of microbial communities, atrazine application history, and soil carbon.
December 1, 2005... Introduction The present research is part of a broader study aimed at reducing loads of agricultural pesticides in the environment using vegetative filters (biofilters) such as grassed waterways or natural grasslands. The focus here is on...

Decomposition of [sup.13]C and [sup.15]N labelled plant residue materials in two different soil types and its impact on soil carbon, nitrogen, aggregate stability, and aggregate formation.
December 1, 2005... Introduction Residue management can impact on soil organic matter (SOM) and long-term sustainability of agricultural soils through its effects on soil fertility, nutrient cycling, and soil structural stability. In the past crop residues...
