In Western Australia’s eastern wheatbelt the sand plain soils are prone to acidification. To neutralise the acidity grain growers apply coastal lime usually sources from sites hundreds of kilometres away from their farms. However as part of a project initiated by the Kwinana East Regional Cropping Solution Network group research is being done to locate and assess on-farm lime sources as an alterna...

Increasing herbicide use over the last two decades has led to concerns over the potential effects herbicides (and their residues) have on soil health. This concern has led to significant, national GRDC investment over the past five years into the potential impacts of increased herbicide use on key soil biological processes. This is being achieved by benchmarking the level of herbicide residues in...

Fungicide resistance is inevitable. That’s a tough message to accept, but experts say resistance is like a train travelling to a destination – nothing will stop it arriving but we can slow it down. On this podcast, fungicide specialist, Nick Poole, suggests a new timetable for the fungicide resistance train.

Big is definitely the case when it comes to spray nozzle sizes, particularly when spraying in sensitive areas during summer. On this podcast, spray expert Bill Gordon details new label requirements, including nozzle sizes, when using 2-4D chemistries. Bill also re-assures us that it’s still possible to do a good spray job with larger nozzles. Further Information: https://grdc.com.au/resources-and-...

Sandy soils account for five million hectares of Australia’s southern grain growing region. Crop water use and productivity on these sandy soils are commonly limited by a range of soil constraints that affect root growth. In this podcast we hear from CSIRO’s Senior Research Scientist Dr Lynne Macdonald who leads GRDC’s sandy soils program in the southern region. The program aims to improve the dia...

A leading science communicator says rather than educating the general public about farming, farmers should ensure that urban people trust farmers to have their best interests at heart. Heather Bray, from the University of Western Australia, says trust in farmers is more important than how deeply city people understand the business of farming. Learn more about your ad choices.

Liming to maintain good soil pH levels and avoiding yield losses is just as important as applying fertiliser for maximising yields. If growers let soil pH levels in the topsoil run-down (pH in CaCl2 < 5.0) they are at risk of creating soil acidity issues at depth which are harder and more expensive to treat. In general, not enough lime has been applied frequently enough to address acidification oc...

Snails may be slow to move, but they are quick to survive baits during late Spring and Summer. This surprising development has been revealed as a result of research into snail mortality on the York Peninsula. This fact and several other tips for managing snails are explained by entomologist Helen Brodie on this podcast. Contact: Helen Brodie 08 8429 0557 Helen.brodie@sa.gov.au Link: https://grdc.c...

A common pest for canola growers to monitor each Spring is the Cabbage Aphid. DPRID research officer Dusty Severtson describes where within the crop to check for the aphid and the use of monitoring tools such as the Crop Scout app to accurately calculate aphid numbers.

Nitrogen 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 south...

Farmers 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.
