FUNCTIONAL CHARACTERISTICS AND FIELDS OF USE

Natural inert, ideal for:

? build substrates for plants that require the presence of carbonate in the substrate;

? with gypsum (1 part of gypsum and 3 parts of marble) if you want to create an acid reaction in the substrate with the release of magnesium ions;

? decorative if placed above the root system of potted plants or on the ground;

? mulch flower beds or areas of the garden where you want to avoid the growth of grasses or weeds.

NB: GUARANTEES

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 comes into 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 (rain, humidity, snow and / or frost) or to any fertilization or irrigation done with particularly aggressive water or which they have elements in solution that can, in some way, alter the chemism - and therefore the color - of the rock itself (eg carbonates in general, salts, iron, manganese, molybdenum, heavy metals in general, etc ...). Remember that all stones that do not undergo chemical treatments can absorb water and with it the previously mentioned elements.

NB: AVAILABILITY OF THE MATERIAL

The material is subject to availability, it is usually taken directly from the manufacturer in the quarry and sent to the customer in order to always have a clean product in excellent condition. We therefore ask our customers to check availability and delivery times by contacting Geosism & Nature sas
