An inorganic soil improver made from ground volcanic rock. It is a natural product that supports plant growth by improving the physico-chemical properties of soil. Basalt meal increases water retention while preventing excessive soil acidification. Additionally, it contains nutrients needed by plants, including nitrogen, phosphorus, and potassium. The product can be used in the cultivation of all types of vegetable, fruit, and ornamental plants (including lawns). Particularly recommended for light or too compact soils, as well as those with too low pH levels.
