• hinders the development of root and stem rot pathogens;

• as fertilizer does not contain chlorine. It is applied successfully for feeding agricultural crops sensitive to chlorine;

• potassium contained in the ash as potash (potassium carbonate) is readily soluble in water;

• helps the microorganisms in the soil during decomposition of organic matter, making them easily accessible substance;

• ash application occurs an aftereffect. The duration of such effect on mineral soils 2-2.5 years, and peat – up to 4 years.

At the same time enriching the soil and lowering its acidity ash improves its structure, facilitates its loosening, creates a favorable soil microbial flora, which has a beneficial effect on health of plants, their survival rate, yield, decorative qualities immunity.

Ash is not used in alkaline soils, on soils with acidity pH 7 and above, as well as for plants that prefer sour soil: azaleas, camellias, rhododendrons, hydrangeas, heathers, conifers and a few others
