The invention relates to the chemistry of synthetic substances polymer in a mixture with organic and natural substances, such as for urban and agricultural purposes, or compositions for mulching different types of soils, lawns, parks and gardens.

Was formerly known such a composition of the mulch, which is used polyacrylamide, urea, lignosulfonate, potassium chloride and water in the following ratio, wt.%: polyacrylamide 0,25-0,75, lignosulfonate 0.5 to 1.5, urea, 0.4 to 0.8, potassium chloride 1-3, water - the rest (patent of Russia №2034899 C1, 1995, a class of the international classification of patents SC 17/00).

However, this patent did not use natural materials is a significant disadvantage. Nature provides many suitable materials, many mosses, different types of wood waste, bark, shavings, chips. In this case, different types of wood can be combined with different kinds of synthetic materials - polymers, their waste if they are harmless to the environment.

In the technical result of the invention is the use of numerous kinds of natural materials, that is, the extension of the range of compositions for mulching soils.

This result is achieved by the fact that the composition of the mulch, according to the invention, contains lignosulphonate, carbamide, Na-carboxymethyl cellulose, potassium chloride, and ka is este natural supplements moss species Takakiopsida and needles of larch Larix komarovii, water in the following ratio, wt. %:

needles of larch Larix komaroviifrom 9.1 to 9.5

or

moss species Takakiopsida10-15
