Abstract:
1. A method of increasing the fertility of a soil by inducing an increase in at least one enzymatic activity contained in said soil, comprising: adding to the soil an effective amount of a solid mineral composition comprising: from 4.58% to 77.8% of calcium carbonate, from 3.85% to 69.29% of dolomite, from 5.7% to 12.4% of sodium chloride, from 4.25% to 8.49% of lignosulphate, from 0.37% to 2.44% of potassium sulphate, from 0.01% to 0.07% of magnesium oxide, and from 0.009% to 0.066% of elemental sulphur, wherein the above percentages are weight percentages of each of the compounds, relative to the total weight of dry matter of said mineral composition, and the solid mineral composition induces an increase in at least one enzymatic activity contained in said soil, selected from group consisting of (i) phosphatase, (ii) β-xylosidase, (iii) α-glucosidase and (iv) β-glucosidase.
