Use of a solid mineral composition to increase the fertility of soil cultivation or meadow

摘要

Use of a solid mineral composition comprising the formula (I): - Calcium carbonate 4.58% to 77.8% - Dolomite 3.85% to 69.29% - Sodium chloride 5.7% 12.4% - lignosulfonate from 4.25% to 8.49% - potassium sulfate 0.37% 2.44% - magnesium oxide 0.01% 0.07% - elemental sulfur 0.009 % to 0.066% consisting of the above percentages in weight percentages of each of the compounds, all with respect alpeso dry matter of said mineral composition, to increase soil fertility causing increased at least enzimáticacontenida activity said soil, selected from (i) phosphatase, (ii) the b-xylosidase, (iii) a-glucosidase and (iv) lab-glucosidase.
