Combating subsoil acidity for sustainable production through managing plant cation-anion uptake. At least 50 million hectares of topsoil and 23 million ha of subsoil of Australian land are presently affected by acidity, with this area expanding due to the ongoing processes of acidification. Surface liming is ineffective in neutralizing subsoil acidity. The project will develop an innovative method that stimulates root proliferation and ameliorates subsoil acidity through manipulating the balance ....Combating subsoil acidity for sustainable production through managing plant cation-anion uptake. At least 50 million hectares of topsoil and 23 million ha of subsoil of Australian land are presently affected by acidity, with this area expanding due to the ongoing processes of acidification. Surface liming is ineffective in neutralizing subsoil acidity. The project will develop an innovative method that stimulates root proliferation and ameliorates subsoil acidity through manipulating the balance of nutrient uptake by plants. The effects of the developed method on nutrient use efficiency and leaching loss, and crop yields will be quantified under different soil types and climatic conditions.Read moreRead less
Water and nutrient stress detection in broad acre crops using remote sensing. The national benefit of the remote sensing of water and nutrient levels in crops comes from improved agricultural practice; leading to cost savings, reduced water usage and reduced pollution. This benefit will arise since irrigation and fertiliser application can be exactly tailored to the measured needs of broad-acre crops. In Australia, water is a scarce resource. Reducing consumption by irrigators will have signi ....Water and nutrient stress detection in broad acre crops using remote sensing. The national benefit of the remote sensing of water and nutrient levels in crops comes from improved agricultural practice; leading to cost savings, reduced water usage and reduced pollution. This benefit will arise since irrigation and fertiliser application can be exactly tailored to the measured needs of broad-acre crops. In Australia, water is a scarce resource. Reducing consumption by irrigators will have significant downstream benefits. By remote measurement of nutrient variation within paddocks, fertiliser applications can be optimised. Minimum excess fertiliser will then be present and this will minimise runoff and potential downstream water pollution.Read moreRead less

Summary
Agro-ecosystem sensor capability for elevated CO2 free air research facility. Agro-ecosystem sensor capability for elevated carbon dioxide-free air research facility: This project will provide infrastructure upgrades to the Australian Grains Free Air Carbon dioxide Enrichment (AGFACE) facility, globally the only FACE facility in low rainfall, non-irrigated agri-ecosystems. Low rainfall, non-irrigated agriculture systems play a very significant role in global crop production and are predicted to ....Agro-ecosystem sensor capability for elevated CO2 free air research facility. Agro-ecosystem sensor capability for elevated carbon dioxide-free air research facility: This project will provide infrastructure upgrades to the Australian Grains Free Air Carbon dioxide Enrichment (AGFACE) facility, globally the only FACE facility in low rainfall, non-irrigated agri-ecosystems. Low rainfall, non-irrigated agriculture systems play a very significant role in global crop production and are predicted to be negatively affected by climate changes. The requested infrastructure will enable direct, plot scale measurements of crop water balance and water status, including crucial influence factors such as root growth and architecture and crop canopy temperatures, and allow manipulation experiments to develop adaptation options to improve crop resource use efficiencies.

Use of Distichlis spicata for sustainable forage production on saline land to manage dryland salinity. Sustainable and productive use of salt-affected lands is a priority for many farmers. This project aims to develop management strategies that optimise yield, water use and nutritive value of Distichlis spicata (a salt-tolerant grass) forage on salinised lands, and to understand how this forage species affects the salt cycle, water use and fertility improvement of saline soils.
