Soil that is regularly sprayed with chemical fertilisers tends to have fewer worms. It becomes sad, low quality and, frankly, starts to smell like a pair of old socks! When soil is left alone to support grazing cows and sheep it tends to fare much better. See for yourself. If you lift a spadeful of soil from a well-drained, regeneratively farmed field it will smell delicious and be home to plenty of worms and bugs (plus more organic matter that you can’t see – like networks of fungi). Biology at its best: arthropods, roots, bacteria and fungi making for fertile, rich soil. Plants love it, and in turn so do all the things that rely on plants for food and shelter.
