Description

Standard protocol for measuring organic matter decomposition by separating detritus into size fractions, oven-drying, weighing, and ashing to determine ash-free dry mass (AFDM). Accounts for inorganic content to isolate organic matter loss.

Typical Equipment

  • 1-mm mesh screen
  • oven
  • Wiley mill
  • 550°C furnace
  • LECO CNS Elemental Analyzer model #2000

Output Measurements

  • detritus AFDM
  • decomposition rates
  • C:N ratios
  • C:P ratios
