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.
