Phoma koolunga is one of three species that cause ascochyta blight (synonym: blackspot) of field pea (Pisum sativum L.) in Australia. P. koolunga was first described in 2009 in South Australia and has since been reported in Western Australia and Victoria. However, the origin of the pathogen and its host range remain largely unknown. The aim of this...

Honey bees, Apis mellifera, have been implicated as vectors of plant pathogens. However, the survival of spores of plant pathogenic fungi through the digestive tract of workers has not been investigated. As workers defecate outside the hive, transport of hives could give rise to biosecurity concerns if fungal spores remain viable following passage...

A theoretical model is developed for the estimation of the toxicity of a large number of chemicals to a group of species for which the log-toxicity values have strong linear relationships. The model is a multi-dimensional functional relationship (FR) that allows for many missing values. It depends on an unobserved variate (denoted by ξ in the text)...

A logistic model was used to describe the removal of water-soluble carbon from synthetic winery and distillery wastewaters containing 14C-labelled lactic acid and glycerol after their application to the top-soils of a brown earth and a solod. Decreases in the radioactivity of soil extracts during the first hour after application were ascribed to mi...
Article
The removal of soluble organic carbon from synthetic winery wastewater containing uniformly 14Clabelled lactic acid and glycerol applied repeatedly to soils sampled at various depths from a brown earth and solod was determined from decreases in the solution concentration of 14C of soil extracts.

Systematic methods that allow a relative assessment of off-site impact of pesticides are of great value to pesticide users, natural resource managers and regulators in choosing the pesticides and practices with the least detrimental impact on the environment. Risk indicators are regarded as useful tools in minimizing off-site impacts of pesticides...

Abstract-Two soil microbial processes, substrate-induced nitrification (SIN) and substrate-induced respiration (SIR), were measured in the topsoils of 12 Australian field trials that were amended separately with increasing concentrations of ZnSO4 or CuSO4. The median effect concentration (EC50) values for Zn and Cu based on total metal concentratio...

Well-clogging remains a major operational issue, particularly in light of the increased attention being given to the reuse of reclaimed water through the method of aquifer storage and recovery (ASR) in seasonally arid regions. At a reclaimed water ASR trial site in a limestone aquifer at Bolivar in South Australia, rates of clogging were related to...

Arsenic contamination in groundwater in Bangladesh has become an additional concern vis-à-vis its use for irrigation purposes. Even if arsenic-safe drinking-water is assured, the question of irrigating soils with arsenic-laden groundwater will continue for years to come. Immediate attention should be given to assess the possibility of accumulating...
Article
The rate of leaf elongation in radiata pine (Pinus radiata) and wheat seedlings was closely related to the osmotic potential of the rooting solution. Sudden stress application and removal treatments caused immediate changes in the leaf elongation rate and a new steady-state rate independent of the old was quickly established. The osmotic potential...

Simulated composite sampling was carried out using data from a contaminated site. The values obtained by composite sampling were compared with the results obtained using discrete (individual) samples. It is appropriate to use a modified investigation level (MIL) when using composite samples. The MIL is lower than the standard investigation level, (...

A study was conducted to examine changes in total and phytoavailable Cd in a soil that had received inputs of Cd due to fertilization with single superphosphate (SSP) at various rates since 1948. Accumulation of Cd in the soil was highly correlated to the application rate of SSP. No evidence was found to indicate offsite movement of Cd, either thro...

Several strains of Bacillus subtilis and B. cereus, isolated and selected in China for their ability to promote plant growth and control root disease (yield-increasing bacteria), were tested for their potential to control take-all, caused by Gaeumannomyces graminis var. tritici, and rhizoctonia root rot caused by R. solani AG-8 on wheat seedlings g...
Article
The cotton strip assay (CSA) is an established technique for measuring soil microbial activity. The technique involves burying cotton strips and measuring their tensile strength after a certain time. This gives a measure of the rotting rate, R, of the cotton strips. R is then a measure of soil microbial activity. This paper examines properties of t...
Article
A measure quantifying unequal use of carbon sources, the Gini coefficient (G), has been developed to allow comparisons of the observed functional diversity of bacterial soil communities. This approach was applied to the analysis of substrate utilisation data obtained from using BIOLOG microtiter plates in a study which compared decomposition proces...
Article
The food-preference behaviour of earthworms was examined in order to develop earthworm feeds which might act as a microbial carrier in earthworm-mediated dispersal of beneficial microorganisms in soil. A circular choice chamber containing 18 feeding stations was used to assess the food-type preference of four earthworm species (Aporrectodea caligin...

A study demonstrated the ability of the earthworms Aporrectodea rosea and Aporrectodea trapezoides (added at an equivalent density of 100 or 300 m−2) to reduce the disease severity of Rhizoctonia soiani Kühn on wheat in the field. In a calcareous sandy loam artificially infested with R. solani, the addition of these earthworms caused a significant...
