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, 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 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 and, as natural additives moss species Jungermanniales and needles of juniper Juniperus X. media Gold Coast, the water in the following ratio, wt.%:

lignosulfonateof 0.1-0.4

PA-carboxymethylcellulose0,3-0,4
potassium chloride1-3
moss species Jungermanniales10-15
needles of juniper Juniperus H. media Gold Coast8-9

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

moss species Jungermanniales10-15
needles of juniper Juniperus H. media Gold Coastfrom 9.1 to 9.5

or

moss species Jungermanniales10-15

The composition prepared as follows.

The decree is installed ingredients are subjected separately to grinding and after mixing in the aquatic environment.

The table shows various examples of variants of the invention, the water content of each sample is the rest up to 100 wt.%.
