Oats has a wonderful reputation amongst consumers, especially those in Asia, as a very healthy product. So it makes sense to find more ways to present oats to those consumers. And that is exactly what the Australian Export Grains Innovation Centre is doing developing new products such as oat-based rice and oat-based noodles. On this podcast we speak to one of the very enthusiastic people behind th...

Just how quickly, as farmers, we can change the nature of weeds is perfectly spotlighted by how quickly barley grass and brome grass have reacted to our attempts to control them in cropping paddocks. On this podcast Associate Professor Gurjeet Gill explains how these grasses have learned to adapt to control methods and are now lasting longer in the seedbank than they were just 20 years ago. Contac...

Field Peas can be problematic for WA growers to grow, but a simple management practice could change that. Dr Sarita Bennet from the Centre for Crop and Disease Management in WA has trialled using cereal stubble as a form of trellis for the field pea plants to climb. While broadacre trials are needed, Dr Bennett says the early results are positive. Contact: Sarita Bennet 08 9266 2740 sarita.bennett...

Western Australia’s Department of Primary Industries and Regional Development senior researcher Mark Seymour and Esperance Port Zone grain grower Ron Longbottom feature in this podcast about Lentils. In WA growers have been cautious about including this pulse in their cropping program because of variable yields and harvesting challenges. However new lentil varieties and modern harvester fronts hav...

Barley grass in the southern cropping region is becoming more prominent as a problem weed for croppers – as herbicide resistance emerges and as the plant evolves develops new behaviours. A region wide series of trials is taking place, including work being carried out at Birchip in western Victoria by the Birchip Cropping Group, with the overall project being overseen by weed and cropping specialis...

How do you take soil samples from your paddocks? A leading soil scientist maintains that many farmers are leaving a lot of valuable information buried in the paddock, which could be easily accessed with a slightly different approach to sampling. On this podcast, Jason Codon invites you to look at soil sampling with soil variability in mind. Contact: Jason Codon 02 6933 2278 jcondon@csu.edu.au Link...

And you thought you were responsible for that amazing wheat crop. Think again. There are people in back offices all over Australia who know the seed you sow, infinitely better that you could hope. These are the people of SAGI – Statistics for the Australian Grains Industry. The name does not even hint what SAGI does. Take a listen and find out about the best friends you will ever have in the grain...

They may be tiny but the damage they can potentially do is far from small. Root Lesion Nematodes are well known as a problem, but there is still much to learn about them and their impact on crops. A new investment by GRDC aims to fill in some knowledge gaps in parts of WA and develop further options for growers seeking to better control the nematodes if they are proving a problem in individual pad...

Trials in Western Australia are showing how well canola can out compete ryegrass if some simple management changes are made. At a trial site in Kojunup, that was blanketed in ryegrass plants, adjusting seeding rates, seed size and row spacing had a dramatic impact on ryegrass plant numbers.

Crop competition is one of the key pathways to controlling unwanted weeds in your paddocks. On this podcast we look at one trial in Western Australia that is testing crop competition against prolific ryegrass populations, proving that out-competing weeds really works. The trial is also looking at the pre-emergent herbicide degradation, particularly in dry times. AHRI’s Mike Ashworth provides some...

A leading soil scientist has argued for a more strategic approach to nitrogen application. One way of doing that is by increasing soil carbon levels. But the CSIRO’s Jeff Baldock goes one step further and argues that putting a value on soil organic carbon would encourage farmers to grow more legumes.

Nick Gillett from the WA’s eastern wheat belt has been making use of carbonate rich soils from his own farm to correct the pH of his farm’s acidic soils, rather than truck-in coastal. An option that saves freight costs, which can then be put towards spreading more of his farm sourced lime over more hectares to improve his soils and crop yields.

How economically viable is incorporating organic matters into your sub-soil? That’s what new research funded by GRDC is trying to ascertain. While it’s been long understood that some sub-soils constrain root growth, just how that could be feasibly addressed has been sticking point. On this podcast Dr Roger Armstrong from Agriculture Victoria discusses ways sub-soil constraints may be overcome. Con...

The speed at which weeds develop resistance to herbicides makes farmer vigilance if paramount importance. On this podcast, weed scientist, Dr Chris Preston reveals the current resistance status of both grass and broadleaf weeds.

Trials are underway in Western Australia to measure the suitability of Flax (or Linseed) as a viable and profitable break crop in systems that have few other alternatives, at the moment. Flax has been grown in WA’s sandy soils in the past but was dropped for the system when a market disappeared. On this podcast Bronwyn Copestake from Southern Dirt talks about the trials and also potential markets...

Entomologists, with the help of growers and grower groups, are looking at whether chaff lines and other harvest weed seed control are having an impact on invertebrate populations in a paddock. Survey work is underway to find out if insect behaviour and movement are affected by extra chaff left in the paddock after harvest. On this podcast, DPIRD entomologist, Svetlana Micic takes us into the paddo...

DPIRD researchers, led by Dr Craig Scanlan, have been investigating nitrogen (N), phosphorus (P) and potassium (K) crop use efficiency, soil storage and yield responses. The current body of evidence used to support N, P, and K decisions is inadequate across a range of situations and this uncertainty has led to some lack of grower confidence in fertiliser recommendations. These decision gaps exist...

Sandy soils, typical to parts of Western Australia and found in South Australia’s and Victoria’s mallee country, create considerable and costly grain constraints. In WA water repellency, resulting in low nutrient use efficiency and poor crop establishment, affects around 10 million hectares. WA’s annual price tag put on lost production through water repellence is estimated at $250 million. GRDC is...

Shrinking the difference between your possible crop yield and your actual crop yield is one way of increasing your profitability.

A new grain cleaning method is being trialled in WA to enable growers to further reduce the presence of snails in their harvested grain and oilseeds. It’s a snail roller, in common use in Victoria, but new to WA. On this podcast Nathan Dovey from Stirlings to the Coast Farmers talks about the advantages and some of the drawbacks that farmers will have using a snail roller. Contact: Nathan Dovey 04...

At a glance you can now determine just how much your local climate has changed over the past 60 years. The Bureau of Meteorology has published climate guides based on your Natural Resource Management (NRM) area. The guides are a part of the Federal Government’s Drought Initiative. On this podcast we speak to one of the authors of the guides and he reveals some data that may – or may not – surprise...

Esperance-based grower Gavin Egan started using clay spreading, delving and deep ripping to ameliorate soil water repellence and compaction issues seven years ago. For Gavin, the results have paid off. What was typical Western Australian flat Mallee country, producing around 2t/ha cereal crops, is now delivering double those yields. This topic was the focus of the GRDC investment Soil Constraints...
