FUNCTIONAL CHARACTERISTICS AND FIELDS OF USE
Natural inert material, ideal for:
? to create substrates for plants that need carbonate in the substrate;
? with gypsum (1 part of gypsum and 3 parts of marble) if you want to create acid reaction in the substrate with also release of magnesium ions;
? decorative if placed above the root system of potted plants or on the ground;
Mulch flower beds or garden areas where you want to avoid the growth of herbs or weeds.

NB: WARRANTIES
Geosism & Nature sas certifies that the rock sold in this listing is totally natural and has not undergone any type of chemical treatment that could in any way pollute the soil or the crops with which it is put in contact. For the same reasons, Geosism & Nature sas is not responsible for any changes in color of the stone due to the climatic conditions of the place (rainfall, humidity, snow and / or frost) or to any fertilizations or irrigations made with particularly aggressive water or which they present elements in solution that can, in some way, alter the chemistry - and therefore the coloring - of the rock itself (e.g. carbonates in general, salts, iron, manganese, molybdenum, heavy metals in general, etc ...). Remember that all the stones that do not undergo chemical treatments, can absorb water and with it the previously mentioned elements.
