If you prefer, dried blood, alfalfa, soybean, or cottonseed meals can be substituted. Nitrogen is released quickly from them, so it is best to wait until spring to add it to your soil. Ten pounds of blood meal supplies the same amount of nitrogen as 10-20 bushels of manure, but without the added benefit of all the organic matter that manure contains.
- Phosphorus: P stands for phosphorus, which is necessary for germination, strong root growth, flowers, and fruit. It helps plants absorb minerals, grow strong stems, and withstand disease. Rock phosphate provides phosphorus, magnesium, and trace minerals. Rock powders are wonderful soil enhancements. They are slow acting but long lasting, so they need to be applied only every 3 to 4 years. Bone meal and bone char are more readily available sources of phosphorus.
- Potassium: K stands for potassium or potash. It regulates the flow of water in plant cells and is necessary for flowering, fruiting, and disease resistance. A lack of potassium will cause plants to have weak stems and stunted growth.
