Northern Grazing Systems Project Development

Control of grazing distribution, management of stocking rate, wet season spelling and fire

Northern Grazing Systems Bioeconomic analysis and regional assessment

This project is part of the Northern Grazing Systems (NGS) projects which aim to increase adoption of innovative best-practice grazing management by beef producers throughout Queensland, Northern Territory and the Kimberley and Pilbara regions of Western Australia.

Northern Beef Scoping Study

Northern Beef Scoping Study. To investigate alternate pathways for the northern Australia beef industry on a regional basis and assess their contribution to increased productivity and maintain condition.

Ageing validation of northern carp populations

The Carp is considered a threat to our native river fish and ecosystems by its ability to adapt to almost any fresh water body and through its feeding and breeding habits, change environmental parameters such as turbidity, light and water temperatures. This project forms part of the Invasive Animal CRC's freshwater program and is part of a strategy to develop control measures for carp. The age and size at maturity for carp in the northern part of their range (ie. Queensland) is currently unknown.

Optimising growth paths of beef cattle in northern Australia for increased profit

Strategies for increasing growth of cattle using different growth paths.

Hardwoods Nutrient/Disease Interactions

Interactions of nutrients and disease expression in hardwood plantations.

ITC Hardwoods Nutrition R&D

Hardwoods nutrition R&D to improve tree growth, wood quality and resistance to disease attack. Improved diagnotic tools. North Queensland and Burnett region soils.

Deployment of Elite Tropical and Subtropical Hardwoods

Commercialisation agreements supporting plantation development, carbon sequestration, climate change of hardwood species in Queensland.

Relocation of intensive crop production systems to northern Australia

To adapt to climate variability and a lack of irrigation water, businesses and growers in southern Australia, northern New South Wales and southern Queensland are, or are considering, migrating their businesses to northern Australia.

Northern Integrated Disease Management

This project has the overall aim of reducing the impacts of diseases of winter cereals, pulses, sunflower sorghum and nematodes on farming systems in the GRDC northern region. Integrated disease management packages which involve combinations of resistance, targeted fungicide applications, cultural practices such as rotations, and disease modelling will be developed and extended to clients. Structured surveillance activities will enable the monitoring of the distribution and importance of diseases and pathotypes, the early detection of significant outbreaks of endemic and exotic diseases, and a rapid and appropriate response to these outbreaks.

Defining critical soil nutrient concentrations in soils supporting grains and cotton in Northern NSW and Queensland

This project focussed on the phosphorus (P) and potassium (K) status of northern cropping soils. Stores of P and K have been depleted by crop removal and limited fertiliser application, with depletion most significant in the subsoil. Soil testing strategies are confounded by slowly available mineral reserves with uncertain availability. The utility of new soil tests was assessed to measure these reserves, their availability to plants quantified and a regional sampling strategy undertaken to identify areas of greatest P and K deficit. Fertiliser application strategies for P and K have been tested and the interactions between these and other nutrients have been determined in a large field program.

DAQ00152 Herbicide Tolerance Screening in Northern Region (Phase IV)

The previous projects (phase I - III) highlighted that northern region wheat and barley cultivars differ considerably in their sensitivity to herbicides. The new project will focus on increased screening of advanced breeding lines and new cultivars lines to commonly used herbicides, for barley, chickpea and wheat. Studies on impact of environment on herbicide x genotype responses will also be undertaken with the national team. The new information will be added to the existing information package on herbicide tolerance. Thus, adverse impacts of herbicides on productivity in northern region will be reduced, as growers and agronomists will select safer herbicides for their sown variety, or select more tolerant varieties for their important herbicides.

GRDC Evaluating the role of brassica crops in South West Queensland and Northern New South Wales grain cropping system

Project to evaluate the role of brassica crops in the western farming system area.
