A system designed to optimise fertilising strategies for radiata pine plantations in the Green Triangle (SE South Australia and SW Victoria) is being jointly developed by CSIRO, the Forest and Wood Products Research and Development Corporation (FWPRDC) and key softwood growers in the region.
According to CSIRO Forestry and Forest Products (CFFP) spokesman, Dr Barrie May, improved nutrient management practices could significantly increase the productivity of Australias radiata pine plantations, boost internal rates of return and improve management flexibility.
"Its estimated that an improved system for predicting stand growth response to nitrogen (N) and phosphorous (P) and optimising application strategies for different site and stand conditions could increase average internal rate-of-return dollars spent on fertiliser application from around six per cent at present to up to 30 per cent," Dr May says.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
