Description

The invention relates to the chemistry of synthetic substances - polymeric in mixture 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 of components, wt.%: Polyacrylamide 0.25-0.75, lignosulfonate 0.5-1.5, carbamide 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 environmentally friendly.

The technical result of the invention is the use of numerous types of natural materials, that is, expanding 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 Pallavicinia and pine needles Picea pungens, 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 Pallavicinia 10-15 needles spruce picea pungens 8-9 water rest.

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

moss species Pallavicinia 10-15 needles spruce picea pungens 9.1-9.5

or

moss species Pallavicinia 10-15 needles spruce picea pungens 9.8-11

or

moss species Pallavicinia 15,5-17 needles spruce picea pungens 8-9

or

moss species Pallavicinia 17.8-18 needles spruce picea pungens 8-9

or

moss species Pallavicinia 17.8-18 needles spruce picea pungens 9.8-10

The composition is prepared as follows.

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