Regenerative Grazing at Saddlescombe Farm

It’s National Farmhouse Breakfast Week, and Molly Puzey tells us about the regenerative grazing programme at Saddlescombe Farm. TAP has supported this project by helping with soil testing to monitor how soil health changes over the years, and also buying herbal ley seeds, to establish new fields of varied plants.
