Can activated carbon be used as fertilizer?

Activated carbon as fertilizer

Activated carbon itself does not have many nutrients, but due to its porosity, it can absorb large amounts of water and fertilizers. Due to this property, the electrolytes in the soil have a strong regulating effect. At this time, the electrolytes can buffer some nutrients that are not too high in water, and then slowly release them under the action of the plant roots.

Activated carbon can be used as flower fertilizer because the composition of activated carbon is very similar to that of wood ash. Using it to grow flowers can promote the growth of the root system, allowing the roots to grow better, thereby allowing the flowers to grow vigorously and easily fill the pots. Flowers that are usually suitable for activated carbon cultivation include Milan, crabapple, camellia, jasmine, pine, palm, etc.

How to make activated carbon fertilizer

1. Put the purchased activated carbon directly into the soil, and use the adsorption effect of activated carbon to fix the effective ingredients of the flower fertilizer, and then release them slowly, so that the plants can use them effectively and reduce the loss of fertilizer.

2. Place the used activated carbon in the soil and maintain it as usual.

Key points for using activated carbon fertilizer

1. Because activated carbon has very good air permeability, using it to grow flowers can increase the air permeability of the potting soil, making it less likely that water will accumulate in the flowers. However, be careful to use an appropriate amount of activated carbon, and don't use too much, otherwise it will affect the growth of the plants.

2. Activated carbon is mainly used for adsorption. If it is mixed into the flower soil, it will inevitably cause the sudden adsorption of some particles in the air, which will cause sudden blockage, so you must replace the activated carbon frequently.
