FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of synthetic substances - polymer substances in a mixture with organic and natural substances and specifically to compositions for mulching different types of soil, lawn and parking areas. The technical result is achieved in a mulching composition which contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Jungermanniales moss and Juniperus h. Wiltonii juniper needles, and water. The ingredients are 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, Jungermanniales moss 10-15, Juniperus h. Wiltonii juniper needles 8-9, and water - the balance. Other versions of polymer-natural mulching compositions are also disclosed.

EFFECT: wider range of soil mulching compositions.
