GRDC Podcast

At the 2020 Grains Research Update at Goondiwindi digital soil mapping specialist Ed Jones from the University of Sydney, gave a presentation on mapping soil properties and their impact on yield.

It’s what in the near future will become the way growers and their advisors calculate what management a paddock, or section of a paddock needs to increase crop yield and maximise grower profit.

The technique uses data from multiple sources, applies machine learning and delivers recommendations in weeks that until recently took decades to record, digest, trial and apply.

New research has shown just how deep canola roots will travel in their search for moisture late in the season. Trials have shown that there are significant yield advantages from early sown canbola that experiences a dry finish. But there are trade offs.

In this podcast CSIRO’s John Kirkegaard reveals just how low canola roots go and the benefits that can be derived from early sown canola.

A grain grower survey conducted across 25 farm businesses in Western Australia’s northern agricultural region found the majority considered their cereal crop yields were being adversely affected by the inefficient use of micronutrients.

In this podcast, grower Dylan Hirsch, based at Latham in WA, talks us through this survey and the broader GRDC investment behind it.

The investment is a two-year project that aims to identify the requirements for, and benefits of, micronutrient foliar application in medium-to-low rainfall areas of WA’s Northern Agricultural Region.

The research project is led by Western Australian grain grower group, the Liebe Group, in partnership with Murdoch University. Mr Hirsch is a member of the research group.

Controlled Traffic Farming is in simple terms driving your heavy vehicles on the same wheel tracks every time you’re in the paddock.

In Australia’s southeastern grain growing region Controlled Traffic Farming has been widely adopted in high and medium rainfall zones but not so much in low rainfall zones.

With investment from the GRDC a research project was undertaken to find out why this farming system was not being adopted in Low Rainfall Zones and if there are benefits in doing so - and there are!

Fall Armyworm, Spodoptera frugiperda was detected in Australia for the first time in January 2020 and a warning was issued to grain growers to inspect crops for signs of the pest’s presence.

The larval stage of the moth is similar in appearance to many caterpillars already present in agricultural and horticultural crops and can cause severe economical damage, even total crop destruction.

At the 2020 Grains Research Update at Goondiwindi principle entomologist with Queensland’s Department of Agriculture and Fisheries, Melina Miles provided background to the Fall Armyworm’s detection in Queensland, explained what damage to look for and described what features identify this caterpillar from the many other caterpillar pests commonly found in Australia.

Ironstone gravels are important cropping soils and a better understanding about the mineralogy and physical characteristics of these soils, especially their soil moisture holding capacity and high rates of phosphorus ‘fixation’ is urgently required.

So the GRDC has invested in new research, led by the University of Western Australia, to study and understand these soils to help growers maximise crop productivity from these soils.

GRDC’s investment in faba bean breeding has contributed to the delivery of new and improved Faba bean varieties to grain growers.

In Western Australia’s Esperance Port Zone the high rainfall makes Faba beans a suitable legume to include in crop rotations and WA’s Department of Primary Industries and Regional Development senior research scientist Mark Seymour has been working with growers to make the most of the benefits a pulse in the rotation can bring to cropping systems.

A new research project in the Southern Region will take the principles of Precision Agriculture and apply them to addressing sub-soil constraints.

Simply put, this innovative approach will identify the location of poorly performing soil, potentially reducing the areas within a paddock that need soil amelioration work to be done. Professor Roger Armstrong from Agriculture Victoria explains more on this podcast.

Esperance Port Zone grain grower Neil Wandel has been including faba beans in his crop rotations for 4 decades. While they might not be the highest value legume he could grow, the range of benefits faba beans bring to his paddocks make them a favourite rotation crop.
