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 using a mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Sphaerocarpus moss and Larix lyallii larch 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, Sphaerocarpus moss 10-15, Larix lyallii larch needles 8-9, water - the balance. Other versions of polymer-natural mulching compositions are also disclosed.EFFECT: wider range of soil mulching compositions.3 cl, 1 tbl |
