Amendments to the Land Title Act 1994 (Qld)

Wholesale amendments to the Land Title Act 1994 (Qld) were recently introduced with the passing of the Natural Resources and Other Legislation Amendment Act 2005 (Qld). The amendments were preceded by an extensive review of issues associated with the operation of the freehold land register and consultation with a number of stakeholders. The three articles that follow address different issues associated with these statutory amendments. The first article provides a brief overview of the amendments. The second article deals with particular amendments designed to combat mortgage fraud. In the third article, the question posed is whether further statutory amendment could better protect unregistered interests.

An examination of recent taxation amendments, corporate law reforms and Queensland legislative reforms affecting nonprofit organisations

There is a tax amendment bill which will be debated. The Government has promised to outline its plan for the reform of the taxation system sometime this year. The plans appear to go beyond the mere introduction of some sort of goods and services tax to reform of the whole taxation system including fiscal relations with the States. Not for profit organisations will find their taxation environment will change. Governments are reluctant to permit exemptions to a GST style arrangements. GST trade offs such as reduced income tax rates and abolishing indirect taxes are useless to nonprofit organisations, as many are already exempt from such imposts. Administrative changes to tax collections may also have an impact. If the government decides to make an individual PAYE taxpayer return optional in exchange for no or standard deductions, this may have an effect on fundraising. The FBT and salary packaging schemes that not for profit organisations use will be under intense scrutiny. A regionalisation of the ATO along the successful model of the ASC would see discrete areas such as not for profit exemptions being centralised in one regional office for the whole of Australia. For example the Tasmanian ASC Office has the responsibility for much work in respect of corporate charities and not for profit companies.

Validation of β-actin used as endogenous control for gene expression analysis in mechanobiology studies : amendments

We write in response to the letter by Liu et al. [1] commenting on our article, ‘‘Mesenchymal Stem Cells Regulate Angiogenesis According to Their Mechanical Environment’’ [2]. The study by Liu et al. demonstrates that the commonly used endogeneous reference gene (ERG), b-actin, is upregulated by mechanical loading, indicating a potential bias in the determined target gene expression when normalizing to b-actin, such as in our report on unchanged vascular endothelial growth factor (VEGF) and hypoxia-inducible factors (HIF)-1a mRNA levels in mechanically loaded mesenchymal stem cells (MSCs).

Amendments potentially time-barred : A practical approach

In Mineral Resources Engineering Services Pty Ltd as Trustee for the Meakin Investment Trust v Commonwealth Bank of Australia: Hay v Commonwealth Bank of Australia [2015] QSC 62 Philip McMurdo J considered challenges to amended statements of claim in two related actions. The amendments were potentially time-barred and his Honour considered in particular the date from which the amendments should take effect.

Influence of organic amendments on greenhouse gas emissions and N use efficiency in sub-tropical cropping systems

This thesis investigated the impact of organic sources of nutrients on greenhouse gas emissions (carbon dioxide, nitrous oxide and methane), nitrogen use efficiency and biomass production in subtropical cropping soils. The study was conducted in two main soil types in subtropical ecosystems, sandy loam soil and clay soil, with a variety of organic materials from agro-industrial residues and crop residues. It is important for recycling of agro-industrial residues and agricultural residues and the mitigation of greenhouse gas emissions and nitrogen use efficiency.

Rootzone amendments to improve soil moisture relations under newly-laid sod

Three experiments were conducted on the use of water retaining amendments under newly-laid turf mats. The work focused on the first 12 weeks of establishment. In soils that already possessed a good water-holding capacity, water retaining amendments did not provide any benefit. On a sand-based profile, a rooting depth of 200 mm was achieved with soil amendment products within three weeks of laying turf. Most products differed in their performance relative to each other at each three weekly measurement interval. Polyacrylamide gels gave superior results when the crystals were incorporated into the soil profile. They were not suitable for broadcasting at the soil/sod interface. Finer grades of crystals were less likely to be subject to excessive expansion than medium grade crystals after heavy rainfall. Turf establishment was more responsive to products at higher application rates, however these higher rates may result in surface stability problems.

Influence of soil organic amendments on suppression of the burrowing nematode, Radopholus similis, on the growth of bananas.

Radopholus similis is a major constraint to banana production in Australia and growers have relied on nematicides to manage production losses. The use of organic amendments is one method that may reduce the need for nematicides, but there is limited knowledge of the influence of organic amendments on endo-migratory nematodes, such as R. similis. Nine different amendments, namely, mill mud, mill ash, biosolids, municipal waste compost, banana residue, grass hay, legume hay, molasses and calcium silicate were applied to the three major soil types of the wet tropics region used for banana production. The nutrient content of the amendments was also determined. Banana plants were inoculated with R. similis and grown in the soil-amendment mix for 12-weeks in a glasshouse experiment. Assessments of plant growth, plant-parasitic nematodes and soil nematode community characteristics were made at the termination of the experiment. Significant suppression of plant-parasitic nematodes occurred in soils amended with legume hay, grass hay, banana residue and mill mud relative to untreated soil. These amendments were found to have the highest N and C content. The application of banana residue and mill mud significantly increased shoot dry weight at the termination of the experiment relative to untreated soil. Furthermore, the applications of banana residue, grass hay, mill mud and municipal waste compost increased the potential for suppression of plant-parasitic nematodes through antagonistic activity. The application of amendments that are high in C and N appeared to be able to induce suppression of plant-parasitic nematodes in bananas, by developing a more favourable environment for antagonistic organisms.

Assessment of phytostabilization of Pb/Zn mine soils with organic amendments and a native metallicolous ecotype of Festuca Rubra l.: implications for amendment selection and recovery of soil health

La contaminación del suelo es una de las principales amenazas para los ecosistemas y la salud humana. Actualmente, desde un punto de vista tanto económico como ambiental, la fitoestabilización es la mejor tecnología para remediar suelos contaminados con elevadas concentraciones de metales como son los suelos mineros. La fitoestabilización asistida consiste en el empleo de plantas y enmiendas orgánicas y/o inorgánicas con el fin de reducir la movilidad y la biodisponibilidad de los contaminantes y recuperar la salud de suelo. En este trabajo se han realizado ensayos en microcosmos y en campo centrándonos en la salud del suelo minero contaminado con Pb y Zn durante un proceso de fitoestabilización empleando enmiendas orgánicas (purines vacunos, gallinaza, estiércol de oveja y lodos de papelera mezclados con gallinaza) y/o la especie metalífera Festuca rubra con el objetivo de (i) estudiar las interacciones suelo-enmienda responsables de los cambios inducidos por el proceso de quimioestabilización en las propiedades físicoquímicas y biológicas del suelo, (ii) evaluar la efectividad del proceso de fitoestabilización sobre suelos vegetados y de la revegetación sobre suelos desnudos (iii) valorar la idoneidad de distintos indicadores químicos y biológicos (parámetros microbianos y de la vegetación) para monitorizar la efectividad de la fitoestabilización asistida en términos de reducción de la biodisponibilidad de metales en el suelo, mejora de la vegetación y de la recuperación de la salud del suelo. La aplicación de enmiendas al suelo minero supone una entrada de materia orgánica y nutrientes que conduce a una disminución de la biodisponibilidad de metales, facilitando la colonización de las plantas y el crecimiento de la vegetación nativa, además de estimular la actividad microbiana del suelo. El pH del suelo es un factor crítico que condiciona la movilidad de los metales y la toxicidad del suelo. Las poblaciones microbianas de las enmiendas no modificaron la diversidad funcional de las comunidades microbianas nativas de la mina. Los purines vacunos y los lodos de papelera mezclados con gallinaza son los tratamientos más efectivos en el proceso de fitoestabilización asistida bajo condiciones de campo. La gallinaza fue el tratamiento que más estimuló el crecimiento de la vegetación nativa y la colonización en los suelos desnudos. El bioensayo de elongación radical de lechuga es un test sensible, sencillo y barato para evaluar la biodisponibilidad de metal y la ecotoxicidad del suelo. Los tocoferoles son biomarcadores de exposición a metales con potencial para su implementación en bioensayos de toxicidad. Este trabajo permite concluir que la población metalífera de F. rubra, combinada con enmiendas orgánicas, es una excelente candidata para los proyectos de fitoestabilización asistida. Además, la monitorización simultánea de los parámetros fisicoquímicos y microbiológicos del suelo y de su ecotoxicidad permite una evaluación adecuada de la salud del suelo, así como la selección de enmiendas apropiadas para el desarrollo de un proceso fitoestabilizador.
