The Liverpool Plains catchment faces a number of natural resource issues including dryland salinity, which has been attributed to removal of native vegetation, an increase in rainfall and the use of long fallow cropping systems. Opportunity cropping, where a crop is sown once the soil profile...

The Commonwealth of Australia Water Act 2007 changed the priority for water use in the Murray-Darling Basin (MDB) to first ensure environmentally sustainable levels of extraction and then to maximise net economic returns to the community from water use. The Murray- Darling Basin Authority (MDBA)...

In this study, the possible impacts of different prices of carbon on farm profitability in two dairy farm businesses with different feeding systems operated over five years were analysed. The feeding systems were a ryegrass pasture-based system (RM) and a complementary forage-based system (CF)....

The issue of insecticide resistance to Helicoverpa insects is of increasing concern to the Australian cotton industry. In this paper we begin to consider this issue using bioeconomic modelling and analysis. We develop management strategies at the farm level within an integrated resistance...

Soil fertility decline and soil management for crop production are important issues for grain growers in northern New South Wales and southern and central Queensland. In this paper a stochastic dynamic economic analysis of soil fertility management is presented to derive optimal fertility...

Farm and catchment managers in Australia face decisions about controlling invasive native species (or scrub) which may infest agricultural land. The treatment of this land to remove the infestation and re-establish native pastures is likely to be expensive for landholders. Yet there are...

Episodes of rainfall irregularity and soil moisture deficit have focused attention on the widespread limitation of water supply on winter cereal crop production in Australia. This has motivated a number of efforts at breeding for improved drought tolerance. A recent example involves a cellular...

Economic losses and costs associated with weeds in dryland cotton production are important, both for growers and for industry bodies when making decisions about research priorities and research and development funding. A survey was conducted to provide information on weed types, control...
