Quck answer
Blood and bone meal is a natural fertilizer that can be made at home. To make your own blood and bone meal, follow these steps:
1. Collect animal bones and blood from a local butcher or farmer.
2. Clean the bones by boiling them in water for several hours.
3. Remove any remaining flesh or tissue from the bones.
4. Dry the bones in the sun or in an oven at a low temperature.
5. Grind the bones into a fine powder using a blender or food processor.
6. Mix the powdered bones with dried blood in a 2:1 ratio.
7. Store the blood and bone meal in an airtight container.
8. Use the fertilizer in your garden or plants as needed.
Making your own blood and bone meal is a cost-effective and sustainable way to nourish your plants.
Blood and bone meals are rich in various nutrients and can be used to fertilize your garden in different ways. Bone meal contains high levels of phosphorus which helps plants grow healthy root systems, while blood meal is rich in nitrogen which promotes leaf growth and aids in photosynthesis. While helpful to plants that require them, both soil additives can be harmful if overused.
Precautions to Take
Prior to adding bone or blood meal to your soil, you should conduct a soil test to ensure that it is necessary. The nitrogen in blood meal can burn plants if used excessively, and bone meal can have the same effect. Excessive amounts of phosphorous can cause a plant to put in more effort to create healthy roots and is only beneficial when the pH level of the soil is below 7.0.
It’s also important to note that blood and bone meal can be easily purchased at garden centers if you don’t wish to make your own. While making your own is simple and ensures nothing goes to waste, both processes can produce unpleasant odors. The smell of making blood meal is worse than that of making bone meal, but neither process is pleasant. If you have an outdoor kitchen, it’s best to use it for these projects. If not, make sure to open your kitchen windows and ventilate the space well.
Creating Bone Meal
Commercial bone meal is typically made from cow bones, but most DIYers use leftover chicken, turkey, or other bones from their regular cooking. If you prefer cow bones, you can try to obtain them from a local butcher or slaughterhouse. However, any bones left over from a meal will work perfectly fine.
- Collect the bones from your meal and remove any meat, fat, or sinew from them.
- Boil the bones for at least six hours to soften them and remove any remaining meat or fat. You can also use a pressure cooker to speed up the process. Cook the bones on the highest setting for at least two hours. Note that cow bones are thicker than poultry bones and may require a longer cooking time.
- Take the bones out of the pressure cooker and break them into smaller pieces, about three inches in size. Cow bones may be thicker and require tapping with a hammer to break them, while bird bones can be easily cut with scissors.
- Place the bone pieces in a single layer on a tray and put them in a dehydrator. Set the dehydrator to the highest setting and run it for approximately 12 hours.
- Crush the dehydrated bones into a powder with a mortar and pestle.
Creating Blood Meal
Be aware that creating blood meal is not for the faint of heart. Blood meal isn’t a euphemism for something else; it’s exactly what it sounds like, so you will be working with blood. You should wear old clothing and gloves and work carefully. If you spill the blood, your kitchen may look like a murder scene and be challenging to clean up.
- Obtain some animal blood. If you are a hunter, you can collect the blood that flows from the animal into a container. Alternatively, you can check with a local abattoir to see if they can provide you with the required amount of blood.
- Boil the blood for a few hours until it thickens. The process is not precise, and you should aim to eliminate most of the water content until the blood is about 10 to 12 percent moist. Your target is a dense paste.
- Transfer the thickened blood into shallow trays to dry out. If you reside in a warm climate, you may place the trays in the sun until the blood dries to the point where it crumbles when touched. If not, place the blood trays in an oven at 170 to 180 degrees Fahrenheit or a food dehydrator set to 120 degrees.
- Grind the dried blood into a fine powder and apply it to your soil or use it as a top layer as needed.
