Bonemeal is a fertilizer that is made from animal bones. It is commonly used to improve soil fertility and to provide essential nutrients to plants. However, there are many other terms that can be used interchangeably with the word "bonemeal". For instance, it can be called ground or powdered bone, bone flour, bone dust, bone meal dust, or bone ash. These terms describe the same product, which is created by grinding or pulverizing animal bones. Regardless of the term used, bonemeal is an excellent source of phosphorous and calcium, both of which are important for healthy plant growth.
