Like blood meal and bone meal, hoof and horn meal is a by-product of the meat processing industry. As such it may not be for the squeamish, but it does make an excellent soil amendment. In fact, it’s one of the better organic nitrogen sources available and, with a 12-2-0 NPK rating, it also adds a nice dash of phosphorous to the mix. It’s also alkaline in nature, so it’s a good choice for sweetening acidic soils; even better, the nitrogen locked inside the meal is released slowly, so that it won’t burn your plants.
