Hoof and horn is one of the best organic nitrogen fertilisers, and contains a nice dash of phosphorous to boot. With a slow natural release of nitrogen, some immediately available, with the rest continuing to release over 4-5 months, it is perfect for use under glass as well as also being used as an ingredient in other fertilisers such as John Innes Base. This 100% organic fertiliser is a by-product of meat processing industries.
