Dry organic fertilizers can be made from a single material, such as rock phosphate or kelp, or can be a blend of many ingredients. Almost all organic fertilizers provide a broad array of nutrients, but blends are specially formulated to provide balanced amounts of nitrogen, potassium, and phosphorus, as well as micronutrients. There are several commercial blends, but you can make you own general-purpose fertilizer by mixing individual soil amendments as well.
