Bone meal powder is a type of organic fertilizer made from ground animal bones that have been steamed and then finely ground into a powder. The powder is a rich source of phosphorus, calcium, and other minerals that are essential for plant growth and development. It is commonly used in gardening and agriculture as a soil amendment to increase the nutrient content and improve the quality of the soil. Bone meal powder is particularly beneficial for plants that require a lot of phosphorus, such as flowering plants, vegetables, and fruits. It is also often used as a natural pest deterrent due to its strong smell.
