Soil Research: Science on the Edge.
July 1, 2001... Soils form the fragile, yet fertile fringe of the Earth. By covering the very edge of our globe, and lying between the aerial and subterranean realms, soils are subject to enormous fluxes of mass and energy, which they reflect, store, or...

The Environmental Mechanic.(Obituary)
July 1, 2001... John Philip AO FRS FAA was killed by accident in Amsterdam in 1999. This tribute provides a complete bibliography and brings together perceptions of the work and of the complex character of the greatest of Australia's environmental scientists....

New horizons in soil fertility management(*).
July 1, 2001... Abstract As the 21st century dawns, we can reflect on the progress made during the 20th century in the fields broadly covered by soil fertility and its management and see that progress has been truly amazing. When we consider the many...

Effects of agricultural management on sodosols in northern Tasmania.(Statistical Data Included)
July 1, 2001... Abstract Attributes of 25 Tasmanian sodosols were assessed using field and laboratory techniques to determine changes associated with 4 typical forms of agricultural management [long-term pasture, cropping with shallow tillage using discs...

Changes in organic and inorganic sulfur fractions and S mineralisation in a Typic Haplustert after long-term cropping with different fertiliser and organic manure inputs.(Statistical Data Included)
July 1, 2001... Abstract Changes in the status of organic and inorganic pools of soil sulfur (S), total nitrogen (N), and organic carbon, and their interrelationships and S mineralisation were examined on a Typic Haplustert soil after a 27-year long-term...

Effects of land-use change from grassland to forest on soil sulfur and arylsulfatase activity in New Zealand.(Statistical Data Included)
July 1, 2001... Abstract The effects of land-use change from grassland to forest on soil sulfur (S) and arylsulfatase enzyme activity were investigated by comparing soils under unimproved grassland and an adjacent 19-year-old exotic forest stand (mixture...

Factors affecting the change in extractable phosphorus following the application of phosphatic fertiliser on pasture soils in southern Victoria.(Statistical Data Included)
July 1, 2001... Abstract Nine pasture soils from high rainfall zones of southern Victoria were analysed for a range of chemical and physical properties before receiving a single application of P fertiliser in the form of triple superphosphate (TSP),...

The influence of soil properties on the effectiveness of phosphate rock fertilisers.(Statistical Data Included)
July 1, 2001... Abstract Eighteen soils from south-western Australia were used to measure the effectiveness of 2 reactive phosphate rocks (RPR) [North Carolina and Sechura (Bayovar) RPRs] relative to superphosphate (relative effectiveness, or RE) using...

A laboratory study of application of basalt dust to highly weathered soils: effect on soil cation chemistry.(Statistical Data Included)
July 1, 2001... Abstract Surface (0-10 cm) samples from 7 highly weathered soils in tropical coastal Queensland were incubated for 3 months at room temperature and at field moisture capacity with basalt dust applied in 2 size fractions: [is less than] 150...

Mineralogy and potassium release from some Western Australian soils and their size fractions.(Statistical Data Included)
July 1, 2001... Abstract Seven surface horizon soils and their sand, silt, and clay fractions were characterised for mineralogy, and K release by extracting samples with 1 mM Ca[Cl.sub.2] solution daily for 10 days. The low silt content is characteristic...

Measurement of unsaturated hydraulic conductivity using tension and drip infiltrometers.(Statistical Data Included)
July 1, 2001... Abstract We investigated differences between constant flux and constant potential methods for determining unsaturated hydraulic conductivity in the laboratory. A cheap and robust method was required. The constant flux drip infiltrometer...

Kinematic cell model of macropore flow from intermittent irrigation pulses.
July 1, 2001... Abstract Significant fluctuations in soil water flux were observed in the drainage hydrographs from lysimeters (1220 mm diam., 900 mm deep) of undisturbed field soil, recorded at 5-min intervals, in response to intermittent 1-min pulses of...

Libardi's method refinement for soil hydraulic conductivity measurement.(Statistical Data Included)
July 1, 2001... Abstract The method of Libardi to estimate soil hydraulic conductivity in the field, during the redistribution of soil water, is discussed and improved. It is shown that if the saturated soil water content is measured at the soil surface,...

Explaining groundwater hydrographs: separating atypical rainfall events from time trends.(Statistical Data Included)
July 1, 2001... Abstract By 1994, an estimated 1.8 million hectares of cleared land in Western Australia was affected by secondary dryland salinity to some extent. The area affected is likely to double in the coming 20 years. The cause of this salinity is...

Effects of sodium-contaminated wastewater on soil permeability of two New Zealand soils.(Statistical Data Included)
July 1, 2001... Abstract There is increasing anecdotal evidence from some land treatment sites in New Zealand that irrigating sodium-contaminated wastewaters onto soils may be causing soil structural problems and reduced permeability. In this study, the...

Differences in sorption behaviour of carbaryl and phosalone in soils from Australia, Pakistan, and the United Kingdom.(Statistical Data Included)
July 1, 2001... Abstract Sorption of 2 nonionic pesticides, carbaryl (1-naphthyl methylcarbamate) and phosalone (S-6-chloro-2,3-dihydro-2-oxobenzoxazol-3-ylmethyl O,O-diethyl phosphorodithioate), was investigated for 48 soils from Australia, Pakistan,...
