GDM is a unique granular product produced from solids removed from digested dairy manure. Manure is first digested anaerobically to make renewable natural gas, then the large cellulosic fibers are removed. We concentrate the suspended solids remaining in the liquid digestate and granulate these valuable nutrients to make a low-dust, well-formed granule that is easy to store and apply. The granule is approximately 2-5 mm and pathogen free.
