Among the various mineral fertilizers currently used in agriculture, there are supplementary fertilizers such as powdered meals obtained from dolomites, limestones, and other carbonate rocks, as well as bentonite, gypsum, phosphorites, and basaltoids. Most of these materials provide the soil with only one or two mineral components. However, basalt meals are an exception. As alkaline and neutral substrates, they enable the formation of highly fertile soils, similar to those found on the slopes of active and extinct volcanic cones.

In its easily decomposable powdered form, basalt supplied to depleted soil causes comprehensive remineralization of the soil substrate. Due to its complex chemical composition (containing 72 elements), this rock provides both major nutrients and trace elements.

After applying basalt meal, the soil forms more stable aggregates, increases its organic matter content, improves water retention in the vegetation layer, and enhances ion exchange. These changes greatly benefit plant nutrition processes and the development of beneficial soil microflora.

Due to the relatively low concentration of individual nutrients, basalt meals are often referred to as a “soil conditioner.” Their key advantages include non-toxicity, even for aquatic animals, and the impossibility of overdosing.
