The best way to build healthy soil is by looking at how Nature maintains soil ecosystems in similar growing conditions and exploring ways to mimic the strategies used in our farms and gardens.
Let me explain by sharing a story… A few years back, some students and I compared the soil at Hill Top Farm with the soil across the road, where there was still forest.
Under the forest canopy, the soil was what I wanted. It was easy to dig, had more earthworms, organic matter and soil aggregates. It was a light bulb moment for me – while I had been busy spreading gypsum, mulch, and compost every year to get these advantages – the forest had done it naturally!

Fast track forwards a few months, and I found another opportunity to compare soil, this time in a temperate climate, between an ancient woodland and adjoining arable field in England.
Historical records suggest the ancient woodland has never been cleared, whereas the field is likely to have been cultivated annually for decades. The woodland soil was crumbly and dark, indicating loads of organic matter, carbon and soil life. In the arable field, just 20 metres away, it was light coloured, had unbreakable clods, and was hard to dig!

Some people say, “that’s all very well, but we won’t feed everyone by growing in ancient woodlands.”
But that’s not the point! What’s relevant is the eco-logic of mimicking the techniques Nature uses, and where possible, the architecture of the plant communities that would naturally grow on your land.
Compare the practices the woodland ecosystem uses to maintain a self-fertilising system with what happens in the arable field (see table below).
