Description
Around 3.8 M ha of gravelly soil contributes to crop production in south west WA. Soil analysis and glasshouse experiments routinely take place in the absence of the ≥2 mm fraction. Typical processes include sample collection, air drying, and sieving (<2 mm) prior to experimentation or analysis. The ≥2 mm fraction is discarded as it is often considered inert, acting as a soil volume diluent, and problematic for routine chemical analysis when intact because of size and representativeness. However, the literature cites that the ≥2 mm fraction may contribute positively to soil chemical, physical and biological properties.
