USING SOLID MINERAL COMPOSITION TO INCREASE FERTILITY OF CULTIVATED SOIL OR GRASSLAND SOIL

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to agriculture and more specifically to fertiliser used particularly in crop farming, horticulture and forestry. Use of a solid mineral composition, having the following formula (I): calcium carbonate 4.58-77.8%, dolomite 3.85-69.29%, sodium chloride 5.7-12.4%, lignosulphate 4.25-8.49%, potassium sulphate 0.37-2.44%, magnesium oxide 0.01-0.07%, elementary sulphur 0.009-0.066%, where the above percentages consist of weight percentages of each of the compounds, relative to the total weight of the mineral composition dry matter, for increasing the fertility of soil by increasing at least one type of enzymatic activity contained in the soil, selected from (i) phosphatase, (ii) β-xylosidase, (iii) α-glucosidase and (iv) β-glucosidase.;EFFECT: invention enables to use the composition to maintain and increase soil fertility, having a good effect on enzymatic activity of soil.;10 cl, 18 dwg, 2 tbl, 5 ex
