FIELD: chemistry.SUBSTANCE: mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Sphagnopsida moss and Juniperus Blue Alps 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, Sphagnopsida moss 10-15, Juniperus Blue Alps juniper needles 8-9, and 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 |
