As Dry ash

Ash extracted from a stove or from a fire will be an excellent fertilizer, significantly improving the composition of the soil. This substance helps to reduce acidity and accelerates the decomposition of organic matter. Ash-based fertilizing can be applied to any type of soil, with the exception of the carbonate type, which is characterized by an alkaline reaction. To obtain dry fertilizer, it is permissible to use ash in its original form, that is, without sifting.

To normalize the composition of the soil before planting plants, it is enough to spray a certain amount of dry ash over it. Then dig up the ground or leave the substance on the site as mulch. Under the influence of moisture, the ash will gradually be absorbed into the soil structure.

Such feeding should be used in the following proportions:

  • per 1 m2 of sandy loam land – 200 g;
  • per 1 m2 of loam – 700 g.

Excessive volume can lead to a change in alkaline parameters in the soil. This will have a negative impact on the life of plants.
