🔬 Microflora & Hyphal Networks
Mycorrhizal fungi extend plant root absorption surface areas up to 1000%. They synthesize glomalin, an insoluble glycoprotein that aggregates sand, silt, and clay particles into erosion-resistant crumb structures.

Lumbricus rubellus (Endogeic Earthworm)
Ecosystem engineer burrowing horizontal feeding channels. Consumes mineral soil and organic matter, producing microbial-rich vermicasts that stabilize soil aggregates and enhance hydraulic conductivity 4-fold.
Soil ecosystem balanced. 9 dynamic macro/micro-taxa active.
Subterranean Ecology & Food Web Architecture
Soil is not inert rock particulate—it is a self-regulating, living biocenosis mediating Earth's global biochemical cycles.
🪳 Mesofauna Shredders & Grazers
Springtails (Collembola) and Oribatid mites regulate fungal communities and decompose coarse plant detritus. Their gut microflora accelerates nutrient mineralization, converting immobilized proteins into bioavailable nitrates.
⚡ Trophic Cascade Dynamics
Bacterial-feeding and predatory nematodes unlock immobilized ammonia as waste excretion right inside the root rhizosphere, delivering immediate, non-synthetic plant fertilization where roots need it most.
How does mechanical inversion tillage destroy the subterranean food web?
Inversion tillage (such as moldboard plowing) pulverizes macroscopic earthworm channels, shears delicate mycorrhizal fungal hyphae, and introduces sudden surges of oxygen that induce bacteria to burn through stable humus as CO₂ gas. This shifts the ecosystem from a balanced fungal-dominated sponge into a compaction-prone, bacterially volatile dust.
What is the QBS-ar (Biological Quality of Soil) index?
QBS-ar (Qualità Biologica del Suolo) measures soil degradation based on microarthropod morphological adaptation to subterranean life. Organisms with high subterranean specialization (blindness, reduced appendages, depigmentation, such as Pauropoda and Protura) receive higher Eco-Morphological Indices (EMI up to 20), indicating mature, uncompacted soil structure.
How is the Nitrogen mineralization calculated in this model?
Turnover is derived from bacterial and fungal predation by nematodes and protozoa. Because microfaunal predators possess a higher C:N ratio (around 30:1) than their bacterial prey (around 5:1), the excess consumed nitrogen is discharged into soil solution as plant-available ammonium (NH₄⁺), estimated here per hectare-year based on organic matter and moisture coefficients.
