Hoof meal or horn meal is a manure, rich in proteins. It is made up of dried and ground animal hooves or horns or both. It contains 12 to 14% nitrogen which is rapidly released in warm soil, and 2 to 3% phosphorus which takes 4 to 6 weeks to release. Horn meal is normally added to soil before planting or sowing and is good for perennials planted in autumn.
