The BettaCrop database currently has information for over 10,000 paddocks and includes over 120 current growers across northern, central and southern areas of NSW. Analysis of the database is conducted each year and is able to provide comparisons of various agronomic and management factors that contribute to achieving high water use efficiency (WUE)... The project commenced in July 2008, and will examine the effects of management practices on WUE. Soil water characteristics will be determined and WUE will be calculated and modelled for the growing season... Passioura & Angus also state that tactical management has the potential to increase yields in favourable seasons with little effect on yields in poor seasons...

The core objectives of the project are to increase the return per unit of applied water and reduce the environmental impact of irrigation in the project area through the roll out of precision irrigation systems that allow the irrigators to more precisely match water application to crop water needs... The project will incorporate: soil moisture and climate sensors to monitor the water balance in their soils and crops and make decisions about when to irrigate and how much and at what rate to apply water to their fields; and control systems and storages to provide users with greater control over the rate and timing of irrigation applications... CICL proposes to overcome these barriers by: providing a significant up-front cost subsidy for the deployment of the infrastructure for precision irrigation systems; avoiding the need for individual irrigators to acquire, deploy and maintain the technologies by offering a full service precision irrigation package that will be deployed and maintained by CICL and partner organisations; providing the near on-demand water supply service to the farm gate that is required in order to precisely match water; and most importantly, training and educating irrigators in the use of precision irrigation technologies and providing water balance and crop information in a user friendly format...

Gains in productivity can be quantified through improvements in the total seasonal water supply accessed by a crop and the conversion of this water to harvestable grain (water use efficiency)... As seasonal water supply is dominated by stored soil water at the start of the season plus in-season rainfall, then there is little growers can do to improve seasonal water supply, except through better..... The expected outcome is to improve the water use efficiency of a paddock and farm by providing the tools for farmers to identify and manage poor performing areas, improve understanding of the factors which cause poor performing patches, and the economic and natural resource management (NRM) benefits to managing these areas differently...

Using a water diviner in a maize field.. Recent efforts to improve on-farm water use efficiencies have resulted in more use of soil moisture monitoring tools, particularly capacitance probes such as C-probe, Enviroscan and Diviner... Probes are typically used to: schedule irrigations - to determine when irrigation is required calculate soil water deficit to work out how much water to apply...

Farming groups, researchers and the Grains Research and Development Corporation are working collaboratively to increase water use efficiency of the Australian grain industry by 10%... Benchmarking wheat water use efficiency in Australia at the shire level The need for a regional benchmark of water use efficiency is many fold: for industry, it allows gaps to be identified and opportunities for improvement in efficiency in the use of water; for funding agencies, it helps to allocate investment in higher-return activities; for policy makers, it contributes to the identification of regional and national vulnerabilities and opportunities... Improving land productivity, profit and water use efficiency of the farm business Farmers have a limited amount of resources (land, capital, machinery, labour) that need to be allocated to alternative activities within the limits imposed by environmental and financial constraints...
