Type: Organic fertilizer / soil amendment
Source: Finely ground or crushed animal bones, typically from cattle or other livestock.
Description: Bone manure is a slow-release, phosphate-rich organic fertilizer traditionally used to improve soil fertility. It is usually processed by crushing and grinding bones into a coarse or fine powder. Its high content of calcium phosphate makes it particularly effective for stimulating root development and encouraging flowering and fruiting in plants.
Nutrient Profile:
- Primary nutrient: Phosphorus (Pâ‚‚Oâ‚…)
- Secondary nutrient: Calcium (Ca)
- Nitrogen content is generally low.
Uses in Gardening & Agriculture:
- Applied to flower beds, vegetable plots, and orchards to promote strong root systems and abundant blooms.
- Particularly beneficial for root crops (e.g., carrots, beets, and parsnips) and flowering plants.
- Can be incorporated into compost or sprinkled directly into soil before planting.
Application Notes:
- Best applied to soil several weeks before planting to allow nutrients to become available.
- Avoid over-application, as excessive phosphorus can interfere with uptake of other nutrients.
- Should be stored in a dry, cool place to prevent spoilage.
Historical & Practical Context:
Bone manure has been used for centuries as a natural soil amendment, valued in traditional gardening for its long-term nutrient release and ability to improve soil structure. Modern horticulture often supplements or replaces bone meal with processed phosphate fertilizers, but organic gardeners continue to use bone manure for its ecological benefits and slow-release properties.
