Native Symbiotic Fungus Increases Shoot Biomass And Grain Yield Of Canola, Khalil Kariman, Craig Scanlan, Zed Rengell
The State of Soil Science in WA
More than 90% of land plant species (including most agricultural crops) form beneficial associations with soil-borne mycorrhizal fungi. Mycorrhizal hyphae allow plants to indirectly explore a large soil volume and forage for nutrients (most importantly P, but also micronutrients) that are usually poorly available in soils due to their immobility. Recent studies using state-of-the-art DNA sequencing technologies have unearthed much more complexity in root-fungal relationships than those discovered using the traditional morphology-based approaches.
Are Ironstone Gravel Soils In Southwest Western Australia: All The Same?, Karen Holmes, Edward Arnold Griffin, Dennis Van Gool
Are Ironstone Gravel Soils In Southwest Western Australia: All The Same?, Karen Holmes, Edward Arnold Griffin, Dennis Van Gool
The State of Soil Science in WA
Ironstone gravel soils are widespread, locally common, and important for cropping in Western Australia (WA). The spatial extent of these soils is reasonably well known, but geographic differences and distinct subgroups of gravel soils are not. We present a novel approach to map ironstone gravel layers and associated fine earth texture classes to improve understanding of gravel soil characteristics and distribution across southwestern WA.

The State of Soil Science in WA
National satellite-derived fractional groundcover products (percentage of green vegetation, dry vegetation, bare soil) are now routinely produced by Geoscience Australia and other groups, and are available for interpretation. The extensive coverage, frequent repeated observations and large archive of historical imagery supports more objective and reproducible methods than previous degradation monitoring efforts that were based on intermittent field surveys of land condition and anecdotal reporting. Landsat (30 m pixel resolution) seasonal composite images will be used to estimate total groundcover throughout the year, and assess the proportion of cropland in the grainbelt below recommended cover thresholds of 50% for wind erosion, …

Nutrient Recovery Via Anaerobic Digestion Of Supermarket Food Waste And Re-Use As Fertiliser In Potting Media For The Urban Retail Market; A Proof Of Concept Using Digestate And Biochar, Bede Mickan, Somayeh Zarezadeh, Sasha Jenkins, Aitian Ren, Zakaria Solaimon, Megan H. Ryan
Nutrient Recovery Via Anaerobic Digestion Of Supermarket Food Waste And Re-Use As Fertiliser In Potting Media For The Urban Retail Market; A Proof Of Concept Using Digestate And Biochar, Bede Mickan, Somayeh Zarezadeh, Sasha Jenkins, Aitian Ren, Zakaria Solaimon, Megan H. Ryan
The State of Soil Science in WA
Food waste can be diverted from landfill and utilised via anaerobic digestion (AD) to produce biogas. The liquid by-product of AD is commonly referred to as digestate, and this can be an organic certifiable biofertilizer. Digestate in Europe is frequently used in agriculture, though is not commonly used in the urban retail market. Biochar is another organic matter which can adsorb and retain the nutrients, and also could decrease the adverse effects of high nitrogen content of soil.
Profile Texture Classes: A New Data-Driven Functional Soil Classification For Southwestern Australia, Edward Arnold Griffin, Karen Holmes
Profile Texture Classes: A New Data-Driven Functional Soil Classification For Southwestern Australia, Edward Arnold Griffin, Karen Holmes
The State of Soil Science in WA
Soil information is critical for efficient and sustainable agricultural management. However, there is typically a hiatus between soil information which government agencies charged with supporting agriculture develop and deliver, and the information land managers can easily use for management in the paddock. This hiatus is largely due to (1) differences in the spatial scale of information needed by these different groups, and (2) communication-style inhibiting soil science information into management advice. We outline and evaluate a ‘three factor functional soil classification’ based on soil texture, depth, and gravel content for south-western WA, referred to as Profile Texture Classes (PTC).
Soil Exchangeable Cations Increase Microbial Carbon Use Efficiency And Microbial Growth In Acidic Soils, Emilia Horn, Emily Cooledge, Anna Ray, Davey Jones, Steve Rushton, Eizabeth Stockdale, Frances C. Hoyle, Yoshi Sawada, Daniel Murphy
Soil Exchangeable Cations Increase Microbial Carbon Use Efficiency And Microbial Growth In Acidic Soils, Emilia Horn, Emily Cooledge, Anna Ray, Davey Jones, Steve Rushton, Eizabeth Stockdale, Frances C. Hoyle, Yoshi Sawada, Daniel Murphy
The State of Soil Science in WA
Microbial growth and function is influenced by the properties of the surrounding soil where surface chemistry mediates interactions between individual organisms and their local microenvironment. We hypothesised that the addition of exchangeable base cations, necessary for microbial biochemical function, will increase microbial growth in acidic soils.

The State of Soil Science in WA
The Western Australian Government is working to conserve and manage the State's natural resources for the benefit of present and future generations. In support of this, the Department of Primary Industries and Regional Development (DPIRD) have prepared a simple instructional field guide for recording and describing Western Australian unique and challenging soils and landscapes.

The State of Soil Science in WA
The examination and comparison of soil and related material transferred in situations of contact is a powerful method for linking persons, vehicles, equipment and locations. The evidential value of soil comparison derives from its widespread distribution, highly variable composition, relative ease of transfer, persistence and resistance to degradation. Sandy soils, present a challenge, with minimal organic material and heavy minerals resulting in limited material for comparisons, regardless of the bulk amounts present.

The Methodology For Farm-Scale Modelling For Spatio-Temporal Prediction Of Soil Carbon Sequestration Under Climate Change, Lynette Abbott, Jolene Otway, Louise Barton, Jennifer Dungait
The State of Soil Science in WA
A methodology for region-specific adaptation of existing soil carbon (C) models was developed by integrating location-specific automated data with local farm-based knowledge. The aim was to optimise the balance between scientific accuracy and farm-scale practicality of C modelling tools to identify the most influential location-specific variables.
Topsoil Evaporation In Water Repellent Soil Affected By Tillage And Claying: Preliminary Case-Study Results, Giacomo Betti, Gaus Azam
Topsoil Evaporation In Water Repellent Soil Affected By Tillage And Claying: Preliminary Case-Study Results, Giacomo Betti, Gaus Azam
The State of Soil Science in WA
Soil water repellence represents one of the major soil constraints to broad-acre agriculture in southern Australia. Topsoil wettability is significantly reduced by the presence of hydrophobic organic compounds, resulting in poor seed germination, early plant establishment and ultimately lower yields. Soil mechanical disturbance (tillage) in combination or not with the addition of clay-rich subsoil (e.g. clay spreading) have been successfully adopted in the Australian broad-acre agriculture for the amelioration of water repellent sandy soils.

Topsoil Water Repellence Increased Early Wheat Growth And Nutrition, Simon Yeap, Richard Bell, Craig Scanlan, Richard Harper
The State of Soil Science in WA
Soil water repellence, derived from the accumulation of hydrophobic organic compounds, is a constraint to crop and pasture production worldwide predominantly in sandy soils. Inhibited water infiltration, unstable wetting, and preferential flow are key hydrologic issues in water-repellent soil which adversely affect plant germination and establishment. However, despite the general understanding that soil water repellence can reduce soil nutrient bioavailability due to the prevalence of dry topsoil, the implications of water-repellent topsoil for plant growth and nutrition per se are unclear.
