Dr Ernest Gordon Hallsworth: scientist and teacher 1/10/1913-14/2/2002.(Obituary)
May 1, 2002... Ernest Gordon Hallsworth was a loving husband, a caring father, a great teacher, a man of supreme optimism, and a leader who encouraged all adventurous scientific research. He was also a witty raconteur, a genial host, and an excellent and...

Indigenous soil and water conservation techniques: effects on runoff, erosion, and crop yields under semi-arid conditions.(Statistical Data Included)
May 1, 2002... Introduction Runoff and soil erosion are serious and widespread land degradation problems in many parts of the world (Hudson 1992). In Kenya, runoff and soil erosion have been identified as major factors in low crop yields since the 1930s,...

Groundwater level reductions under lucerne depend on the landform and groundwater flow systems (local or intermediate).(Statistical Data Included)
May 1, 2002... Introduction Precipitation transports a small amount of airborne salt to the soil (Wood and Wilsmore 1928). In the medium to low rainfall areas (<600 mm per annum), much of this salt has been stored in the soil profile. Clearing of the...

Towards a framework for predicting impacts of land-use on recharge: 1. A review of recharge studies in Australia.(Statistical Data Included)
May 1, 2002... Introduction Secondary salinisation in Australia is generally accepted to have been caused by the aquifer discharge capacity of groundwater systems being exceeded, due to an increase in recharge (Walker et al. 1999). Quantitative...

Spatial and temporal variations of suspended sediment responses from the subtropical Richmond River catchment, NSW, Australia.(New South Wales)(Statistical Data Included)
May 1, 2002... Introduction Like any hydrological process, the delivery of sediment from any catchment area is a stochastic process, which includes deterministic and random components (Novotny and Chesters 1989). The quantity of sediment eroded from a...

Assessment of peroxide oxidation for acid sulfate soil analysis. 1. Reduced inorganic sulfur.(Statistical Data Included)
May 1, 2002... Introduction It is important to have an accurate and reliable measure of the reduced inorganic sulfur (generally assumed to be pyrite) content of acid sulfate soil (ASS) materials to avoid inappropriate or unnecessary treatment leading to...

Assessment of peroxide oxidation for acid sulfate soil analysis. 2. Acidity determination.(Statistical Data Included)
May 1, 2002... Introduction The acid released upon the oxidation of pyrite in acid sulfate soils (ASS) can severely reduce water quality and may cause adverse effects to aquatic life, reduced crop production, and the corrosion of concrete and steel...

A study of atrazine transport through a soil profile on the Gnangara Mound, Western Australia, using LEACHP and Monte Carlo techniques.(Statistical Data Included)
May 1, 2002... Introduction The Gnangara Mound is a superficial aquifer located north of Perth, Western Australia, in a region known as the Northern Swan Coastal Plain. The mound is bounded by the coast, the Swan River, Ellen Brook, Chandala Brook,...

Amorphous alumino-silicate materials in a Brazilian hydromorphic lateritic soil.(Statistical Data Included)
May 1, 2002... Introduction The geology of the Triangulo Mineiro region of Minas Gerais State, Brazil, has been reported by several authors (e.g. Barbosa et al. 1970; Nishiyama 1989). Few studies have focused on the characterisation of the aluminous clay...

Soil acidification as influenced by crop rotations, stubble management, and application of nitrogenous fertiliser, Tarlee, South Australia.(Statistical Data Included)
May 1, 2002... Introduction Soil acidification in its broadest sense can be considered as a summation of natural and anthropogenic processes that lower measured soil pH (Krug and Frink 1983). The intervention of man and agriculture into natural...

A simple phosphorus buffering index for Australian soils.(Statistical Data Included)
May 1, 2002... Introduction Phosphorus (P) sorption is an important process that describes the partitioning of soil P between the sorbed and solution phases. It is commonly defined as P buffering capacity (PBC), which is the soil's capacity to moderate...

Nutrient leaching losses from undisturbed soil cores following applications of piggery wastewater.(Statistical Data Included)
May 1, 2002... Introduction In Australia, land application is as an effective management option for disposing of industrial, agricultural, and municipal wastewater (Menzies et al. 1999; Smith and Bond 1999). Wastewater from intensive livestock industries...

Potassium balance and release kinetics of non-exchangeable K in a Typic Haplustert as influenced by cattle manure application under a soybean--wheat system.(Statistical Data Included)
May 1, 2002... Introduction The phenomenal growth of Indian agricultural production in the past 4 decades was made possible by the extensive use of improved germplasm of crops and increased use of nitrogen (N) fertiliser. There has been, however, no...

Nitrogen fluxes in surface soils of young Eucalyptus nitens plantations in Tasmania.(Statistical Data Included)
May 1, 2002... Introduction Low rates of NNM limit the growth of many of the world's natural and planted forests. In south-east Australia, the growth of many eucalypt plantations is also limited by the low availability of N (Cromer et al. 1993; Bennett...

Note of clarification about: field and laboratory calibration and test of TDR and capacitance techniques for indirect measurement of soil water content, by P. N. J. Lane and D. H. Mackenzie, Vol. 39, pp. 1371-1386.(Brief Article)
May 1, 2002... Lane and Mackenzie (2001) presented a series of curves characterising the soil water content-dielectric constant relationship based on empirical equations from different sources (Fig. 6). It should be noted that the Nadler et al. (1991) curve...
