Reply To: Green manure – dig or no dig?

[Stringfellow]

Green manures are an interesting aspect of organic gardening. Pete Budd on here has posted some great info regarding their use in his allotment near York; try a search and they should come up. I’ve been led to believe that green manures, like other plants, absorb energy from the sun and, in turn, this energy is eventually returned to the soil. Also, the deeper rooting green manures draw minerals from subsoil and, once harvested, leave a legacy of organic matter in the soil which help future growth. So, it seems unlikely that green manures are simply transferring fertility from one site to another?
