Blood and bone fertilizer is an organic fertilizer made from dried blood and ground bone. The blood supplies nitrogen, and the bone supplies phosphorus and calcium, so together they make a gentle, slow-acting feed for vegetables, fruit, flowers and shrubs. Some products also add potash to make a more complete feed.
Agromer supplies blood and bone fertilizer in bulk to distributors, retailers and agricultural buyers.

How it is made
Blood and bones from regulated meat processing plants are heat-treated to destroy pathogens, then dried, ground and blended. In the EU, animal by-products used in fertilizers must be processed under the Animal By-Products Regulation, and many other countries have similar rules.
