Description

The invention relates to the chemistry of polymeric substances used in mixtures with organic synthesized and natural substances to improve the soil in gardening, horticulture, in particular, to compositions for mulching various types of soils, lawns, park areas.

Known (RU, 2034899, publ. 05/10/1995) the composition of the mulching coating containing polyacrylamide, urea, lignosulfonate, potassium chloride and water.

The known technical solution did not contain natural materials that could decompose the soil upon decomposition. In addition, the potassium chloride used was very quickly dissolved when the mulching composition was applied to the soil.

Also known (RU, patent 2497918, publ. 10.11.2013) is a mulching coating composition containing lignosulfonate, urea, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Sphagniidae, pine needles Pinus sylvestris, pine pine shells of Pinus cedar nut Pinus sibirica and chips of Pinus sylvestris pine bark.

This mulching composition has the same drawbacks as the previous analogue, in addition, it contains components that are not usually used in human activities and which must be separately prepared.

The technical problem solved by the developed invention is to expand the range of mulching compositions of a wide scope.

The technical result achieved by the implementation of the developed composition, consists in the disposal of waste from human activities while improving the soil condition.

To achieve the specified technical result, it is proposed to use a mulching composition containing lignosulfonate, urea, Na-carboxymethyl cellulose, nitrophos fertilizer and silage in the ratio (wt.):

lignosulfonate 0.1-0.5 urea 0.4-0.8 Na-carboxymethyl cellulose 0.3-0.4 nitrophoska 3-6 silage 16-20

In addition to the main functions of mulching the soil, the developed composition allows you to effectively dispose of waste from human activities. As part of the mulching, it was proposed to use a silo unsuitable for any reason for use as animal feed (shelf life, detection of unacceptable components, mold, etc.).

In preparing the mulching composition, all components are ground in any known manner using any grinding equipment to the required size (usually 1-3 mm) and mixed using any mixing device. Application to the soil is carried out in any known manner.

The invention will be further illustrated using examples of implementation.

Example 1

The developed composition used in the garden plot for planting cucumbers contains lignosulfonate, urea, Na-carboxymethyl cellulose, nitrophos fertilizer and silage in the ratio (wt.):

lignosulfonate 0.1 urea 0.4 Na-carboxymethyl cellulose 0.3 nitrophoska 3 silage 16

These components were ground using a garden shredder and mixed using it. At the beginning of summer, a layer of mulching coating of the specified composition with a thickness of 5-7 mm was applied to the aisles. During the summer, mulching composition was added twice to a layer thickness of 5-7 mm. During the summer, there was a lack of crust on the soil surface, a weak growth of weeds, a decrease in the need for watering, a decrease in rotting berries, an increase in the number of earthworms.

Example 2

The developed composition used for mulching tomato plantings contains lignosulfonate, urea, Na-carboxymethyl cellulose, nitrophosphate fertilizer and silage in the ratio (wt.):

lignosulfonate 0.5 urea 0.8 Na-carboxymethyl cellulose 0.4 nitrophoska 6 silage twenty

The composition was prepared in a similar way. In early May, a layer about 2 cm thick was poured on the aisles. During the summer, a mulching layer was added once. During the summer, there was a lack of crust on the surface of the soil, a weak growth of weeds, a decrease in the need for watering, and an increase in the number of earthworms.

Example 3

The developed composition used for mulching male squashes planting zucchini contains lignosulfonate, urea, Na-carboxymethyl cellulose, fertilizer nitrophosphate and silage in the ratio (wt.):

lignosulfonate 0.1-0.5 urea 0.6 Na-carboxymethyl cellulose 0.35 nitrophoska four silage eighteen

The composition was prepared in a similar way. In early May, a layer with a thickness of about 1.5 cm was poured on the aisles. During the summer, a mulching layer was added once. During the summer, there was a lack of crust on the surface of the soil, a weak growth of weeds, a decrease in the need for watering, and an increase in the number of earthworms.

Claims (2)

The composition of the mulching coating containing lignosulfonate, urea, Na-carboxymethyl cellulose, characterized in that it further comprises nitrofosk fertilizer and silage in the ratio, parts by weight: lignosulfonate 0.1-0.5 urea 0.4-0.8 Na-carboxymethyl cellulose 0.3-0.4 nitrophoska 3-6 silage 16-20
