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 for this new crop that could deliver a lot more diversity for WA farmers.

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 ...

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 a...

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 prod...

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 ...
