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 is characterised by that it contains lignosulphonate, carbamide, NA-carboxymethyl cellulose, potassium chloride and, as natural additives, Moerckia moss and Pinus koraiensis pine 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; Moerckia moss 10-15; Pinus koraiensis pine needles 8-9; water - the balance.EFFECT: wider range of soil mulching compositions.6 cl, 1 tbl |
