Can furnace ash be used as fertilizer?

Ash as fertilizer

Whether the ash can be used as fertilizer depends on the specific fuel burned. If it is wood ash, it can be used directly as fertilizer to enhance the fertility of the soil, and the plants planted subsequently will grow more vigorously. If it is coal burned, it cannot be used directly as fertilizer.

If the ash is produced by burning grass and wood, it can be used as fertilizer to maintain flowers and plants. It is fully capable of serving as a fertilizer for growing flowers. It is generally suitable for planting flowers that require higher levels of soil nutrients, such as peonies, jasmine, etc. It is also very helpful for the growth of crops in the fields.

How to make fertilizer from furnace ash

1. Soak

The night before using the ash, prepare it into a suspension with a ratio of ash to water of 1:5, then let it ferment and soak overnight to allow the ash and water to fully blend.

2. Spraying

Pour the solution of wood ash and water into a sprinkler bottle, and use the sprinkler bottle to spray this fertile water onto the leaves of the plants. Because of its high potassium content, it can make the plants grow better fruits.

Key points for using ash fertilizer

1. Mix the soil

Furnace ash can be mixed directly into the soil as base fertilizer, but care should be taken not to add too much wood ash to the soil, otherwise there will be too much potassium ions in the soil, causing seedling burns.

2. Mixed water spraying

Furnace ash can also be mixed with water to form a solution of a certain proportion, ultimately achieving the effect of water fertilizer. The solution can be released onto the branches and leaves of the plant by spraying.
