Common topics: Vermicomposting, bioremediation, using earthworms to restore contaminated industrial land (brownfields), organic waste recycling. Providing a model summary of what such a

Key processes

• Physical: aggregate formation, pore network development, reduced bulk density, altered infiltration and water-holding capacity.
• Chemical: accelerated decomposition of organic residues, mineralization of N and P, localized pH modification via cast chemistry.
• Biological: shifts in microbial respiration, enzyme activity; facilitation or suppression of seedling survival depending on species interactions.

Mechanistic Model (Overview)

• State variables: soil bulk density (BD), porosity (P), organic matter (OM), mineral N (Nmin), earthworm biomass/density (W), plant biomass (B), microbial functional group sizes (M).
• Core processes (rate functions):
  • dW/dt = colonization rate(W, substrate quality) + population growth(W, OM) − mortality(stressors)
  • dOM/dt = litter input(B) − decomposition(M, W)
  • dNmin/dt = mineralization(M, OM, W) − plant uptake(B)
  • dBD/dt = −f_bioturbation(W) + compaction inputs
  • dB/dt = plant growth(Nmin, P, OM) − herbivory/competition
• Feedbacks: increased B raises litter inputs, enhancing OM and supporting larger W and M; improved P reduces seedling mortality.
