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, Takakiopsida moss and Larix amurensis 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, Takakiopsida moss 10-15, Larix amurensis larch needles 8-9, water - the balance. Also disclosed are other versions of polymer-natural mulching compositions in which the quantitative content of the needles is changed.EFFECT: wider range of soil mulching compositions.3 cl, 1 tbl |
