Soil is the second largest carbon retailer after the oceans, nevertheless it’s being steadily degraded. One farming group is pioneering a soil well being challenge to point out how natural regenerative agriculture can restore this very important ecosystem
Beneath our toes lies one of the crucial advanced ecosystems on Earth. Teeming with microbes, fungi, earthworms, bugs and the in depth root programs of vegetation, soil is estimated to be residence to greater than half of the planet’s biodiversity. It holds practically 80% of the whole carbon present in terrestrial ecosystems – nevertheless it’s in bother.
Because of deforestation, intensive agriculture, urbanisation and air pollution, round a 3rd of the world’s soil is degraded. Consultants predict this might improve to 90% by 2050, with doubtlessly catastrophic penalties for meals manufacturing, the atmosphere and local weather change. To not point out worms.
Some farmers are properly conscious of what’s at stake – and are taking motion. Soil well being, and its related advantages, has lengthy been one thing of an obsession at Yeo Valley Natural. The dairy model, which sources its milk from 100 farms within the south and west of England, first sampled the soil on 162 hectares (400 acres) of its personal land in 2015. It adopted up with a significant challenge to check the soil at 25 of its provider farms.
Sampling greater than 6,070 hectares, (15,000 acres), it examined for vitamins, pH, natural matter and carbon. It additionally analysed the soil’s construction and counted the variety of worms, a key indicator of soil well being.
“That gave us a great deal of encouraging indicators – together with 23,833 worms! –about completely different farming practices, nevertheless it additionally stated that we have to go greater, we have to go additional, we have to go long run,” says Tom White, regenerative farming supervisor at Yeo Valley Natural.
The model is now rolling out soil testing throughout all of its suppliers, with repeat sampling taken at five-yearly-intervals. The concept is to create a wealthy and rigorous knowledge set on which to base selections round crop rotations, grazing schedules and extra.
Our local weather will change extra and it’ll change into essential that we as farmers take care of the ecosystems that we depend on
Yeo Valley Natural practises what’s often known as regenerative agriculture, a holistic farming methodology the place meals is produced beneath a set of rules that prioritise nature restoration. By minimising disturbance to the soil, defending it with cowl crops, holding dwelling roots within the soil, cultivating a variety of species and utilizing grazing animals to feed the soil with their manure, soil resilience is boosted. And so come up every kind of advantages, from biodiversity to improved water high quality, and from increased charges of carbon sequestration to flood mitigation.

Increasingly more UK farmers are in search of to know how their land may gain advantage from regenerative agriculture, says Liz Bowles, chief govt of Farm Carbon Toolkit, a social enterprise that helps farmers to supply meals inside local weather and nature-positive programs.“Our local weather goes to vary extra … and it’ll change into essential that we as farmers take care of the ecosystems that we depend on – soil, water, air and habitat.”
That pondering resounds with Sophie Alexander, a provider of milk to Yeo Valley Natural, who oversees 1,200 acres of arable land at Hemsworth Farm in Dorset, and is working with the model on soil testing. “There’s a accountability that may’t be ignored to attempt to discover out what greatest observe is,” she says. “The temptation is to oversimplify, nevertheless it’s so advanced: you’re coping with life in all its permutations. The identical approach doesn’t go well with each farm, it doesn’t go well with each soil.
“As a result of we use a wide range of legumes and grasses, with differing rooting programs and rising charges, the range signifies that [whatever the conditions, there will be] one thing resilient sufficient to outlive,” she explains. “It truly is a whole-farm system.”
It’s a decade in for Yeo Valley Natural’s soil testing work and outcomes are promising: natural farming with regenerative rules is doing what it says on the tin. Regardless of the driest spring the UK has seen in 132 years, there was grazing out there for Alexander’s cows proper via the summer season.
“Change in agriculture is kind of sluggish,” says White. “What began as some baggage of soil on our personal farm has now change into an enormous piece of labor. Cattle are wonderful bioreactors – when it rains, microbes actually drip off their backs. In every single place they go, they unfold this life, and it’s the identical life that’s within the soil.”

Soil well being examine
You don’t want numerous fancy tools to evaluate the vitality of your soil. Right here’s what to look out for:
- Dig down round 10cm into damp earth and collect a fair-sized handful of what you discover there. Begin with feeling its texture: it ought to have the consistency and look of chocolate cake, and may crumble if you squeeze it.
- Subsequent, take a great sniff of the soil: it ought to odor wealthy and virtually candy.
- Lastly, spend a couple of minutes watching the soil and the opening you dug it from. Wholesome soil ought to be buzzing with life, from earthworms and floor beetles to spiders and centipedes.
