At Pertwood, we like plants growing on our roads. The road planings we use are relatively porous and by spreading digestate on our roads which provides organic matter for the surface, we are finding that plants are taking advantage of the opportunity to germinate. They in turn penetrate through the material into the top soil beneath and flourish. We are left with nothing more than tracks defined by the wheels of the vehicles using those roads. There is also significant encroachment from the sides which help to ensure that the edges of the roads are almost normal in terms of their ability to support plantlife.
