Soil carbon frontierWork conducted by Clive Kirkby (CSIRO) has investigated the feasibility of increasing soil carbon levels with the use of balanced amounts of nutrients and incorporation of stubble. The overall aim of the project was to raise awareness of farmers about how they can reduce green house gas emissions, sequester soil carbon and make improvements in farm productivity. |

Dryland Legume Pasture Systems: Small plot species adaptation trialLegume pastures have been pivotal to sustainable agricultural development in southern Australia. They provide highly nutritious feed for livestock, act as a disease break for many cereal root pathogens, improve fertility through nitrogen (N) fixation and mixed farming reduces economic risk. Despite these benefits, pasture renovation rates remain low and there is opportunity to improve the quality of the pasture base on many low to medium rainfall mixed farms across southern Australia. A diverse range of pasture legume cultivars are currently available to growers and new material is being developed. Some of these legumes, such as the annual medics, are well adapted to alkaline soils and have high levels of hard seed, which allow them to self-regenerate from |

Dryland Legume Pasture Systems: Boron tolerant annual medicsPart 1: Medic cultivars were grown in soil with high boron levels in a glasshouse, leaf damage symptoms recorded and cultivars allocated to different tolerance groups (Howie 2012). Part 2: The above identified that all spineless burr medic cultivars are susceptible to high boron levels. Screening wild accessions (supplied by the Australian Pasture Genebank) identified a burr medic accession with boron tolerance and vigorous growth. The boron tolerant accession was crossed with current spineless burr medic cultivars Scimitar and Cavalier. F2 plants with high early vigour were selected and a molecular marker used to identify homozygous boron tolerant plants. A single seed descent breeding method using speed breeding was used to obtain uniform lines. Lines were seed increased at Waite in 2018 and lines with the highest agronomic performance selected for 2019 field evaluation trials. A cohort of 16 boron tolerant lines along with their parents and barrel medic cultivars that differ in boron tolerance, were sown at Roseworthy and Minnipa. The trials were managed as best practice first year annual medics to maximise dry matter and seed production. Best practice consists of a high sowing rate (10 kg/ha), controlling broadleaf and grass weeds, monitoring and controlling insects and no grazing. Dry matter production was assessed and pods collected. Seed yield will be determined by April 2020. |

Barley grass control in a three year rotation at EsperanceBarley grass is becoming an increasingly problematic weed in Western Australia. A GRDC funded project sought to increase adoption of integrated weed management tactics for barley grass, by working with grower groups to develop regionally appropriate rotations for optimal control. A survey indicated that in southwest Australia, many growers thought their barley grass was resistant to grass selective herbicides and may have developed late germination to avoid pre-seeding herbicides. In this area barley grass was a major problem in pastures, and often in break crops too.
A three year trial aimed to investigate pre-emergent herbicides and autumn tickle in wheat in 2019, pre-emergent herbicides and crop density in barley in 2020 and grass selective herbicides and crop topping in pasture in 2021. |
