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