FIELD: chemistry.SUBSTANCE: mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Sphagnopsida moss and Juniperus h. Hughes 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 h. Hughes juniper needles 8-9, water - the balance. The amount of Juniperus h. Hughes juniper needles in the second and third versions of the mulching composition is equal to 9.1-9.5 wt % and 9.8-11 wt %, respectively.EFFECT: invention widens the range of soil mulching compositions.3 cl, 1 tbl |
