Herbal leys improve a tired pasture and break up old plough pans. The chicory tap root works down through the pan, thereby reducing vulnerability to drought, and the root draws up minerals and trace elements making them available for our cows. Other herbs like birdsfoot trefoil and plantains aid digestion and reduce bloat and methane production. Clovers fix nitrogen from the air and make it available in the soil and is an important source of nectar. What’s not to like?
