Description

The invention relates to the chemistry of synthetic substances - polymeric mixed with organic and natural substances, for example, for urban and agricultural purposes or - to compositions for mulching various types of soils, lawns, park areas.

Previously known was the composition of the mulching coating in which polyacrylamide, urea, lignosulfonate, potassium chloride and water were used, in the following ratio, wt.%: Polyacrylamide 0.25-0.75, lignosulfonate 0.5-1.5, urea 0 , 4-0.8, potassium chloride 1-3, water the rest (Russian patent No. 2034899 C1, 1995, class of international classification of patents, C09K 17/00).

But such a patent did not use natural materials - this is a significant drawback. In nature, there are many materials suitable for this - many mosses, various types of wood waste, bark, shavings, wood chips. Moreover, different types of wood can be combined with different types of synthetic materials - polymers, their waste - if they are harmless to the environment.

In the invention, the technical result is the use of numerous types of natural materials, that is, the expansion of the arsenal of compositions for mulching soils.

This result is achieved in that the composition of the mulching coating according to the invention contains lignosulfonate, urea, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Moerckia and pine needles Pinus peuce, water in the following ratio, wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss species Moerckia 10-15 pine needles Pinus peuce 8-9 water rest

As options, the following compositions were invented, in which important ratios for moss and needles were changed (selected):

moss species Moerckia 10-15 pine needles Pinus peuce 9.1-9.5

or

moss species Moerckia 10-15 pine needles pinus flight 9.8-11

or

moss species Moerckia 15,5-17 pine needles pinus flight 8-9

or

moss species Moerckia 17.8-18 pine needles pinus flight 8-9

or

moss species Moerckia 17.8-18 pine needles pinus flight 9.8-10

or

moss species Moerckia 17.8-18 pine needles pinus flight 10.6-11

or

moss species Moerckia 17.8-18 pine needles pinus flight 11,2-12

or

moss species Moerckia 17.8-18 pine needles pinus flight 12.1-12.8

The composition is prepared as follows.

These ingredients are individually milled and then mixed in an aqueous medium.
