FIELD: chemistry.SUBSTANCE: mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Sphagnopsida moss and Larix cajanderi 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, Sphagnopsida moss 10-15, Larix cajanderi larch needles 8-9, water - the balance. The moss and larch needles can also be taken in the following ratios, wt %: Sphagnopsida moss 10-15, Larix cajanderi larch needles - 9.1-9.5; or Sphagnopsida moss - 10-15, Larix cajanderi larch needles - 9.8-11.EFFECT: invention widens the range of soil mulching compositions due to use of natural materials and increases environmental friendliness of mulching.3 cl, 1 tbl |
