Prediction of three key hydraulic properties in a soil survey of a small forested catchment.(Statistical Data Included)
March 1, 2002... Introduction The ability of a soil to store and transmit water is essential in determining the suitability of land for a particular use. It influences landscape and ecosystem processes, which in turn affect biological productivity,...

Priming of soil structural and hydrological properties by native woody species, annual crops, and a permanent pasture.(Statistical Data Included)
March 1, 2002... Introduction Roots grow and function optimally where the soil has minimal physical, chemical, and/or biological constraints. An ideal soil structure for root growth and water infiltration should have an air-filled porosity of at least 15%...

Simulating infiltration and the water balance in cropping systems with APSIM-SWIM.(Agricultural Productions Systems Simulator)(Statistical Data Included)
March 1, 2002... Introduction Models have been successfully used to simulate interactions between crops, soil, and the environment. Models such as EPIC (Williams et al. 1985) and PERFECT (Littleboy et al. 1989) have been used for 2 decades to evaluate...

Testing a soil-landscape model for dry greywacke steeplands on three mountain ranges in the South Island, New Zealand.(Statistical Data Included)
March 1, 2002... Introduction Soil-landscape modelling in steeplands A predictive soil-landscape model for steeplands with uniform geology and simple and repeating landforms has been developed by McIntosh et al. (2000). In such terrain they considered...

Risk mapping of soil acidification under Stylosanthes in northern Australian rangelands.
March 1, 2002... Introduction The inclusion of the Stylosanthes (stylos) has proved to be a low cost method of improving the quality of native pasture and legume-based cropping systems in Asia, Africa, South America, and northern Australia (Miller et al....

Charge characteristics of soil in a lowland tropical moist forest in Panama in response to dry-season irrigation.
March 1, 2002... Introduction Water regime is critical to soil properties and processes (Jenny 1941). In the long-term, water regime largely determines weathering intensity of soil minerals and the types and amounts of weathering products (e.g. soil...

Comparison of structural stability, carbon fractions and chemistry of krasnozem soils from adjacent forest and pasture areas in south-western Victoria.(Statistical Data Included)
March 1, 2002... Introduction Krasnozems or Ferrosols are relatively young soils and generally considered to have stable structure due to their high content of sesquioxides and organic matter (Bridge and Bell 1994; Isbell 1994). They are considered to be...

Mineralisation of nitrogen contained in mature subterranean clover, capeweed and annual ryegrass, and subsequent nitrogen use by wheat in dryland farming systems in southern Australia.(Statistical Data Included)
March 1, 2002... Introduction Grazed ley pastures have been a key source of nitrogen (N) in the cereal farming systems of southern Australia since the 1940s (McDonald 1989). Generally, appreciable amounts of N are present in pasture residues that remain...

Nitrate leaching and pasture production from different nitrogen sources on a shallow stoney soil under flood-irrigated dairy pasture.(Statistical Data Included)
March 1, 2002... Introduction The leaching of nitrate (N[O.sub.3.sup.-]) from agricultural land and the subsequent contamination of water resources have been recongised as a major environmental issue that could undermine the long-term sustainability of...

Phosphorus sorption and nitrogen transformation in two soils treated with piggery wastewater.(Statistical Data Included)
March 1, 2002... Introduction Land application is practised in many areas of Australia as an effective management option for disposing of industrial, agricultural, and municipal wastewater. Despite the benefits of applying nutrient-rich wastewater to...

Chromium(VI) leaching from large undisturbed soil lysimeters following application of a simulated copper-chromium-arsenic (CCA) timber preservative.(Statistical Data Included)
March 1, 2002... Introduction Contamination of soils by heavy metals (HM) is an area of increasing environmental concern especially where loadings are high and/or have occurred over a prolonged period of time. Studies involving heavy metal deposition have...
