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, particularly 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, Pellia endiviifolia moss and Juniperus h. Wiltonii juniper 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, Pellia endiviifolia moss 10-15, Juniperus h. Wiltonii juniper needles 8-9, water - the balance.EFFECT: wider range of soil mulching compositions.3 cl, 1 tbl |
