Healthy Soil = Delivering Higher Levels of Crop Nutrition
Watch bacteria, fungi, nematodes, and protozoa work in concert — unlocking minerals from soil particles and driving them upward through mycorrhizal networks into plant roots. Biologically active soil is the upstream driver of nutritional quality in your food.

The Science Behind the Visual

What lives in healthy soil?

This visualisation depicts the living world beneath a regeneratively farmed field. The soil microbiome — earthworms, pollinators, mycorrhizal fungi and microbial communities — is the upstream driver of the nutrient density in your food.

Earthworms

Earthworms are nature's soil engineers — aerating soil, breaking down organic matter, and transporting nutrients to plant roots. One hectare of regenerative farmland can support up to 1.2 tonnes of earthworm biomass.

Microbees & Pollinators

Pollinator health is tightly linked to soil biology. Regenerative farms support 23% higher pollinator populations on average, creating virtuous cycles between soil health, crop yield, and nutrient density.

Root Networks

Deep, healthy root systems are a marker of biologically active soil. Mycorrhizal fungi extend plant root reach by up to 100×, transferring minerals, water, and even chemical signals between plants.
