Description

Standardized wet sieving method using Yoder device to determine soil aggregate size distributions. Measures water-stable aggregates across multiple size classes to assess soil structure.

Typical Equipment

  • Dickson apparatus
  • Yoder device
  • sieves (#4, 10, 17, 70)
  • 2 g L⁻¹ HMP solution

Output Measurements

  • aggregate size distribution
  • geometric mean diameter
  • fine aggregate fraction
