FIELD: chemistry. ^ SUBSTANCE: invention refers to agriculture and concerns method for making fertilisation composition. Method includes the stages as follows: a) interaction of humified mineral chosen from the group including leonardite, lignite, xylolith and peat, in water with gluconic acid added to the specified mineral in amount ensuring reaction medium pH reduced to less than 2.5; and b) sequential addition to the mixture of alkaline reagent in amount ensuring pH reduced to the value corresponding to that of alkaline medium. Besides, the invention concerns liquid fertilisation compositions and granulated fertilisation compositions to be produced by declared method. Additionally, the invention concerns applications of granulated composition as fertiliser, particularly, for plant growth stimulation, application of granulated composition for higher fertility of arable soils or for cleaning of arable soils contaminated with chemical products and/or toxic metal ions. The invention also refers to applications of liquid composition for localised leaves irrigation and/or spraying fertilising. ^ EFFECT: invention allows for improved method for making liquid or solid fertiliser with enhanced properties and extended application. ^ 20 cl, 4 ex |
