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.

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 paddocks.

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 food for thought.

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.

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.

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.

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 in N, P and K fertiliser management because of climate and systems changes that have occurred after most crop nutrition knowledge was first documented in WA.

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 investing in a multi-million-dollar soils and crop nutrition strategy aimed at managing nutrition after ameliorating these kinds of soil constraints. Water repellent soils in Western Australia are fairly common in the west midlands region, in the central wheat belt and also on the south coast. So the main problem with water repellence is it leads to uneven wetting of the soil and inefficient use of rainfall and ultimately lower grain yield.

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 West project. The project is a collaboration between the GRDC and the Department of Primary Industries and Regional Development, and aims to help improve soil constraints and lift yields and grain grower returns.

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 alternative to coastal lime.

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 cropping soils and generating new knowledge about the fate, behaviour and risk of herbicides to productivity and soil biological function.

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 occurring within the whole soil profile, so soil test to depth and calculate lime requirements for 0-10cm, 10-20cm and 20-30cm, not just the top 10cm of soil.

Glyphosate resistance is on the rise in Australia’s grain growing regions. With 17 key weed species already identified as resistant, sustainable herbicide practices have never been so important. In this podcast Andrew Storrie from AGRONOMO discusses what herbicide resistance (or susceptibility) testing options are available to WA growers.

Grain growers in Tasmania could be averaging cereal yields of 7 tonnes per hectare. The top 10 percent of those growers could be doing double that tonnage. This is a major outcome the Hyper Yielding Cereals project wants to see after 5 years of Research, Development and Extension. This podcast will take you to Hagley in northern Tasmania where the GRDC has invested in a major trial to lift feed wheat and barley yields, as well as improve grain quality and reduce the need for the island state to import cereals. Leading the Hyper Yielding Cereals R&D team is Nick Poole from FAR Australia.

Researchers at the Queensland Department of Agriculture and Fisheries are testing the law of unintended consequences – in this case whether wheat varieties that stay greener longer are also prolonging the feeding of aphids on wheat plants. On this podcast, Entomologist, Melina Miles and her team take us into the tiny world of aphids.

After identifying a need to lift cereal yields to take advantage of the extensive soil amelioration work that’s been happening in Western Australia and newfound opportunities to sow early crops, a group of innovative Esperance growers were keen to investigate options. Quenten Knight a member of the Soil Constraints West steering committee and an agronomist with Agronomy Focus in Esperance put together a study tour plan for the group and with a GRDC Grower Development award, the Esperance growers had the means to travel. Their destination was the Hyper Yielding Cereals trial site in New Zealand.

For many central western NSW grain growers in 2018, the decision to graze their cereal crops reaped big rewards. But it’s not as simple as letting a mob of sheep loose on your best farming paddock. On this podcast, Peter Matthews, a Technical Specialist with the NSW Department of Primary Industries discusses the tactical and strategic decisions you need to take for a successful cereal grazing program.
