The invention relates to the chemistry of synthetic substances polymer in a mixture with organic and natural substances, for example, 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 mass %: polyacrylamide, 0.25 to 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, C09K 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 my invention the technical result 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, AB as natural additives moss species of Pellia endiviifolia and needles of juniper Juniperus virginiana Kobold, water footprint. wt.%:

As variants invented the following compounds, which are changed (selected) important relations for moss and pine needles:

moss species of Pellia endiviifolia10-15
needles of juniper Juniperus virginiana Koboldfrom 9.1 to 9.5

or

moss species of Pellia endiviifolia10-15

The composition prepared as follows.

These ingredients are put separately on the ti-milling and after mixing in the aquatic environment.
