AbstractTree pulling, using a hand winch, showed that 14 to 16 year old Sitka spruce trees, established on surface-water gley soils following mole drainage , had an average maximum turning moment almost double that of trees established on DMB plough ribbons. Root excavations showed that this was due to improved rooting depth and spread in the mole draining treatment. Mole draining gave better diameter growth than ploughing on drumlin slopes; on inter-drumlin flats it resulted in poorer growth.
