Agriculture stands on the cusp of a digital revolution, and the same technologies that created the Internet and are transforming medicine are now being applied in our farms and on our fields. Overall, this digital agricultural revolution is being driven by the low cost of collecting data on...

The purpose of this paper is to discuss how farm-level modelers can best extend their research to address issues broader than just farm income. The paper describes how trade-off curves are a valuable tool for summarizing the missing information to policy makers on economic problems related to...

Medic (Medicago spp.) pastures are widely grown in rotation with dryland cereal crops in Mediterranean climate zones of Australia. Attempts since the 1960’s to introduce this system to Mediterranean west Asia and north Africa (the native region of medic) have not lead to significant adoption;...

Herbicide-resistant annual ryegrass (Lolium rigidum) is having a dramatic impact on the management and profitability of continuous cropping systems of southern Australia. In many cases ryegrass populations have exhibited cross resistance. where development of resistance through repeated use of...

Batterham (1987) described a computer program which eases entry of mathematical programming data. Users of the program first use a text editor to enter data in a relatively efficient format, which the program then converts into MPS format as required by most mathematical programming solution...

The relevance of expert systems in agricultural economics research and extension is examined. Some of the limitations of existing expert systems are described. Expert systems are useful for storing and retrieving knowledge and for solving diagnostic problems but not for mathematical...

Australian research into the economics of privately and publicly funded weed control is reviewed. Of the published studies that consider farm-level problems, most have been simplistic. Complexities which affect a farmer's optimal control strategies for crop and pasture weeds are outlined. The...

Prices received by Australian wheat farmers have increasingly depended on grain quality, especially protein concentration. This concentration depends on various agronomic and physical factors including weed competition. In this paper a model of weed management in the presence of grain quality...

Government and non-government conservation agencies have long-term goals and objectives to provide environmental services, such as conserving the biodiversity of Australian native vegetation. In addition to national parks and reserves, private lands are often included in conservation programs to...
