FIELD: chemistry.SUBSTANCE: invention relates 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, Pellia endiviifolia moss and Larix olgensis 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, Pellia endiviifolia moss 10-15, Larix olgensis larch needles 8-9, water - the balance. The amount of Pellia endiviifolia moss and Larix olgensis larch needles in the second and third versions of the mulching composition is equal to 10-15 and 9.1-9.5 or 9.8-11, respectively.EFFECT: wider range of soil mulching compositions.3 cl, 1 tbl |
