Soil Physical Testing

A understanding of a soils physical properties or physical fertility is important as it controls:

  • water and solute movement
  • plant root growth and exploration
  • oxygen diffusion
  • soil stability and erosion
  • compactability and trafficability

SWA can undertake the following soil physical testing:

  • Soil Classification (including field texture, Munsell colour, soil fabric and structure)
  • Particle Size Distribution (including wet and dry sieve, hydrometer and pipette analysis)
  • Aggregate Size Distribution and Stability
  • Emerson Class
  • Particle Density / Specific Gravity
  • Bulk Density
  • Hardsetting Potential
  • Water Repellence
  • Total Porosity and Pore Size Distribution
