We often judge soil health by what we see above ground — leaf colour, crop yield, plant vigour. But the real engine of resilience operates beneath our feet. Through soil microscopy, the Soil Food Web reveals itself as a structured, communicative ecosystem of bacteria, fungi, protozoa and nematodes working in coordination. From plant-controlled rhizosphere biology to quorum sensing and spontaneous nitrogen fixation, this article explores five powerful insights that transform how we think about regenerative land management — and why learning to properly observe soil life may be the most important skill of all.
