SUBSTANCE: invention relates to chemistry of synthetic substances - polymer substances in a mixture with organic and natural substances, for example, for urban and agricultural purposes, or to compositions for mulching different types of soil, lawn and parking areas. The mulching composition is characterised by that it contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Sphagnopsida moss and Larix lariciana larch needles, and water in the following ratios, wt %: lignosulphonate 0.1-0.4, carbamide 0.2-0.6, Na-carboxymethyl cellulose 0.3-0.4, potassium chloride 1-3, Sphagnopsida moss 10-15, Larix lariciana larch needles 8-9, water - the balance. Other versions of polymer-natural mulching quantitative compositions are also disclosed.

EFFECT: wider range of soil mulching compositions.
