Canopy infection by Blackleg – a new evolution
August 28, 2019 00:00 - 10 minutesFarmers in blackleg prone areas of Australia are generally competent in managing the disease in their canola crops. That is until the recent advent of blackleg infection of the upper canopy. This new way blackleg has developed ways to attack canola crops is the focus of this podcast featuring Steve Marcroft from Marcroft Pathology.

Matching Nitrogen to Crop Needs
August 28, 2019 00:00 - 8 minutesNitrogen fertiliser is arguably a farmer’s biggest variable cost, year on year. Providing the correct amount of nitrogen to a growing crop is the key to success. But how best to deliver that nitrogen without seeing it lost to the environment before it reaches the crop? That was the key question for some recent research in western Victoria – research that is still ongoing in many parts of the southern and northern region. Contact: Ash Wallace [email protected] More Informatio...

Dr Khangura joins Deb Bishop to discuss blackleg management tactics and GRDC resources that are available to help WA gro...
Irrigated Cropping Council Survey - Do the numbers before turning on the tap
August 21, 2019 00:00 - 10 minutesWith water such a valuable commodity nowadays, it’s little wonder that irrigators ask themselves whether they are better off selling their water or using it to grow out a crop. It’s a tough question. So GRDC last year asked the Irrigated Cropping Council to see if they could come up with some answers.

Soil Compaction
April 03, 2019 00:00 - 10 minutesSoil is made up of organic and mineral particles and in between these particles are tiny air pockets containing water, soil microbes and fauna. These are essential components for healthy soil and root and crop development. When soil is compacted, the air pockets are squeezed out, compressing the particles closer together making it firmer and more difficult to penetrate. This in turn creates a hostile environment for roots and soil fauna. In this podcast, Wayne Parker, from Western Australia...

Frost risk pt 1: Sowing strategies
March 27, 2019 00:00 - 8 minutesFor some grain growers the potential risk of a frost event damaging their cereal crop can result in a conservative sowing strategy.
