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, Pallavicinia moss and Picea engelmanni fir 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; Pallavicinia moss 10-15; Picea engelmanni fir needles 8-9; water - the balance. Other versions of polymer-natural mulching compositions are also disclosed.EFFECT: wider range of soil mulching compositions.6 cl, 1 tbl |
