Is Human Ash Good for Plants?

Ashes have been used in gardens for centuries as a means of fertilizing and improving soil health. The practice is not limited to wood ash, as human ash can also be used as a fertilizer for plants. However, there are several factors to consider before using human ash in your garden.

What is Human Ash and How is it Produced?

Human ash, also known as cremated remains, is the residue left over after a body has been cremated. The process of cremation typically involves incinerating the body at a high temperature of 1400-1800°F, reducing it to bone fragments and ash. These bone fragments are then pulverized to create a fine, grayish-white powder, which is what we commonly refer to as human ash.

What Nutrients are Found in Human Ash?

Human ash is a good source of several essential nutrients that plants require for their growth and development. These include calcium, phosphorus, and magnesium. It also contains trace amounts of micronutrients like zinc, copper, and iron, which are important for plant health but required in smaller quantities.

Can Human Ash be Used as a Fertilizer?

Human ash can be used as a fertilizer for plants, but there are factors to consider before doing so. For instance, the pH of human ash is typically high, around 10-11, which can make it unsuitable for acidic soils. It's also important to ensure that the ash is free of contaminants, such as metals or chemicals, that may be harmful to the plants.

How to Use Human Ash as a Fertilizer?

If you're considering using human ash as a fertilizer for your plants, it's essential to use it in moderation. Start by mixing a small amount of ash into the soil and wait for a few weeks to observe its effects. If the plants respond positively, you can gradually increase the amount of ash you use.

Human ash can also be mixed with compost to enrich the soil. However, care should be taken not to add too much ash, as this could alter the pH of the compost, making it unsuitable for plants.

In Conclusion

In summary, human ash can be a valuable source of nutrients for plants, but it's important to exercise caution when using it as a fertilizer. Ensure that the ash is pure and free of contaminants and use it in moderation, gradually increasing the amount you use as needed. By doing so, you can create a healthy and vibrant garden, enriched by the nutrients found in human ash.
