Bone meal is a mixture of finely and coarsely ground animal bones and slaughter-house waste products. It is used as an organic fertilizer for plants and as a nutritional supplement for animals. As a slow-release fertilizer, bone meal is primarily used as a source of phosphorus and protein.
Benefits of using Bone Meal in Garden
- Bone meal is an excellent source of phosphorus. It has 12 to 16% of phosphorus. It is beneficial for root crops such as onions, carrots, radishes, turnips, and parsnips. Flowers that grow from bulbs, tubers and corns also benefit largely from its application.
- The phosphorus in it is present in a form that is easily available for plants to use.
- It is also an excellent source of calcium. calcium is a very important nutrient for strong plant growth.
- It protects plants under adverse weather conditions.
- Bone meals also help plants to attain maturity quickly.
- It will not burn plants if you apply too much.
Bone meal, along with a variety of other meals, especially meat meal, is used as a dietary/mineral supplement for livestock. It is used to feed monogastric animals with bone meal from ruminants, and vice versa, to prevent the spread of bovine spongiform encephalopathy (BSE) or "mad cow disease". Proper heat control can reduce salmonella contaminants.
Bone meal once was often used as a human dietary calcium supplement. Research in the 1980s found that many bone meal preparations were contaminated with lead and other toxic metals, and is no longer recommended as a calcium source.
As a fertilizer, the N-P-K (Nitrogen-Phosphorus-Potassium) ratio of bone meal can vary greatly, depending on the source. From a low of 3-15-0 to as high as 2-22-0. , though some steamed bone meals have N-P-Ks of 1-13-0. Bone meal is also an excellent source of calcium, but does not provide enough nitrogen to be beneficial to plants. Plants can only get phosphorus from bone meal if the soil pH is below 7.0 (acidic soil), according to recent Colorado State University research.

Organic fertilizers usually require the use of a variety of fungi in the soil to make the nutrients in the fertilizer bioavailable to the plant. For plants needing phosphorus, the fungi mycorrhiza penetrate the roots and break down the compounds containing the phosphorus for easier absorption and utilization, and in turn the plants supply the mycorrhizae with amino acids and sugars.
In 19th century Europe, large scale production and international trade in bone meal was seen as essential for agricultural development.
