MULCHING COMPOSITION (VERSIONS) Russian patent published in 2013 - IPC C09K17/52 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of synthetic substances - polymer substances in a mixture with organic and natural substances and specifically to compositions for mulching different types of soil, lawn and parking areas. The technical result is achieved using a mulching composition contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride and, as natural additives, Pallavicinia moss and Larix amurensis larch needles, and water. The ingredients are 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, Larix amurensis larch needles 8-9, water - the balance. Other versions of polymer-natural mulching compositions are also disclosed.

EFFECT: wider range of soil mulching compositions.
