A report published on October 28, 2026 highlights the critical role of living soil in the future of UK nature, emphasizing regenerative agriculture practices to restore soil health and mitigate climate change.
The Subterranean Food Web
Healthy soil hosts a vast microscopic ecosystem. According to the European Soil Data Centre, a single teaspoon contains about one billion bacteria, one million fungi, one million protists, and several hundred nematodes. These organisms form a complex food web that breaks down organic matter, recycles nutrients, and creates the foundation for soil fertility. The British Society of Soil Science has produced videos revealing these microscopic communities.
Restoring the Hidden Engine
Decades of intensive farming have depleted UK arable soils of 40 to 60 percent of their organic carbon, according to a 2019 Environment Agency report. Frequent tillage, heavy machinery, and bare fields have led to compaction, erosion, and carbon loss. Regenerative agriculture aims to reverse this decline through year-round cover crops, reduced synthetic fertiliser use, hedgerow planting, and agroforestry. These practices protect topsoil, improve water retention, and rebuild natural fertility. Corporate partnerships such as Purina's work with Landscape Enterprise Networks (LENs) now support 110 UK cereal farmers adopting these methods across 8,000 hectares.
Three Ways Soil Health Mitigates Climate Change
UK soils store an estimated 10 billion tonnes of carbon. Keeping soil undisturbed locks more carbon underground; a "no-dig" approach in gardens helps preserve microbial networks. Healthy, porous soil acts like a sponge, absorbing heavy rain to reduce flood risk and retaining moisture during droughts; mulching with leaves or bark aids this function. Planting leguminous cover crops such as clover enriches soil with natural nitrogen, boosting biodiversity without synthetic chemicals; mixing white clover into lawns supports pollinators and soil health.
