Pesticide fate and behavior in Australian soils in relation to contamination and management of soil and water: a review.
September 1, 1998... Additional keywords: water contamination, groundwater, sorption, desorption, degradation, transport. Introduction Since World War II, there has been a rapid rise in the use of synthetic organic chemicals for the control of weeds,...

Comparison of soil linear shrinkage curve from extracted cores and in situ.
September 1, 1998... Additional keywords: weakly swelling soil, electronic displacement transducer, kriging, methodology, field measurement. Introduction Soil scientists and practitioners have been aware for almost a century (Auchinleck 1912) of the...

Hydrology models DRAINMOD and SWIM applied to large soil lysimeters with artificial drainage.
September 1, 1998... Additional keywords: lysimeter, simulation, soil moisture, validation. Introduction The ability to predict soil water distribution and movement accurately is critical for the realistic estimation of most biological and plant...

September 1, 1998... Additional keywords: oxisols, organic carbon, permanganate fractions, aggregate stability, infiltration, cation exchange capacity. Introduction Red Ferrosols of the inland Burnett region in south-east Queensland and the Atherton...

Effects of sodium accumulation on soil physical properties under an effluent-irrigated plantation.
September 1, 1998... Additional keywords: exchangeable sodium percentage, dispersion index, hydraulic conductivity, structural stability. Introduction The pressure to avoid the disposal of nutrient-rich effluents into fresh water bodies or the ocean has...

The economics of soil structural degradation under cropping: some empirical estimates form New Zealand.
September 1, 1998... Additional keywords: contingent valuation, compaction. Introduction This paper reports some results from an economic study of soil compaction in the Manawatu region of New Zealand. The term 'soil compaction' describes in general...

Changes in extractable and microbial C, N, and P in a Western Australian wheatbelt soil following simulated summer rainfall. (carbon, nitrogen and phosphorus)
September 1, 1998... Introduction Organic matter, nutrient concentrations, and soil microbial activity generally tend to be greatest in the top few centimetres of uncultivated soils (Woods 1989). A marked concentration of microbial biomass and N...

The influence of the soil matrix on nitrogen mineralisation and nitrification. II. The pore system as a framework for mapping the organisation of the soil matrix.
September 1, 1998... Introduction There is now a great deal of evidence that soils which have different structural, textural, and physico-chemical properties display distinctly different patterns of mineralisation. The mechanisms advanced to explain these...
