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, 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 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.

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 mulch coating according to the invention contains lignosulfonate, urea, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Bryopsida and juniper needles Juniperus virginiana 'Glauca', 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 of the species Bryopsida 10-15 juniper needles Juniperus virginiana 'Glauca' 8-9 water rest.

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

moss of the species Bryopsida 10-15 juniper needles Juniperus virginiana 'Glauca' 9.1-9.5

or

moss of the species Bryopsida 10-15 juniper needles Juniperus virginiana 'Glauca' 9.8-11

or

moss of the species Bryopsida 15,5-17 juniper needles Juniperus virginiana 'Glauca' 8-9

or

moss of the species Bryopsida 17.8-18 juniper needles Juniperus virginiana 'Glauca' 8-9

or

moss of the species Bryopsida 17.8-18 juniper needles Juniperus virginiana 'Glauca' 9.8-10

The composition is prepared as follows.

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

The table provides various examples for embodiments of the invention.
