In spring, the soil under the settled mulching cover remains loose, soft and easy to process.

It is recommended to mix heterogeneous mulching materials so that they complement each other's properties.

Organic mulching materials must have a C: N ratio in excess of 70: 1, so that the decomposition process is sustained with a slow decay and mineralization of nutrients.

The mulching cover should be year-round, the torn off weeds can be left on the surface of the mulch.

Mulching materials must be thoroughly crushed before spreading them over the soil surface, this increases the area of ​​contact of the particles with the soil and accelerates the process of decomposition and release of nutrients.

Mulching of heavy clay soils

Mulching of clay soils requires patience, as the results do not appear immediately, the first signs of improvement can be observed only after 3-4 years. Heavy soils take time to rebuild all their processes into a permanent mulching system, but the beginning of perestroika will have a positive effect: the soil structure becomes more airy, loose and lumpy, the soil will be enriched with humus. Mulching of clay soils has a number of rules, observance of which will help to achieve better results.

Before spreading the mulching layer, carefully loosen the ground so that the lower layer of the mulch is partially worked into the soil.

The thickness of the mulching layer on clay soils should be increased gradually, updating it with small portions of material.

The mulching layer should not be thicker than 2 cm, otherwise with insufficient ventilation and increased moisture, especially during prolonged rains, stagnant decay of the lower layer of mulch may occur.

Mulching clay soils better with heterogeneous materials with different C: N ratios and particle sizes, fine material, such as grass and foliage, must be mixed with coarser.

As the mulching of heavy soils is aimed at their thorough fertilization and the creation of the humus layer, we must especially carefully treat the decomposition process of the mulching cover. To this end, the mulching materials should be supplemented with "organic fertilizers, bone and horny flour, decomposition catalysts, immature compost, littered bedding manure to activate the process of decomposition and fertilization of the soil.

Creation of a uniform mulching layer of organic materials between rows of crops contributes to the preservation of soil moisture, eliminates the drying and overheating of the soil, supports its loose structure, which in a complex stimulates the growth and development of crops. Especially responsive to mulching all kinds of cabbage, cabbage lettuce, tomatoes, peppers, celery, asparagus

In the spring for rapid warming up of heavy cold soils of the mulch layer it is better to clean and restore it after drying and warming up the soil.

When covering the soil with a mulching material, consider its characteristics, the thickness of the cover depends on this. Mulching cover should not cause soil compaction and anaerobic decay processes, which can occur due to the difficult access of oxygen to the soil.

Before applying a layer of mulch to the surface of the soil, it should be loosely loosened. Especially it concerns heavy soils.

Allocate the winter, summer and long-term

mulching. They differ in the types of materials, the time of application to the soil, the thickness of the required layer and its purpose.

The mulching layer suppresses the growth of weeds, prevents their spreading over the area of ​​the site and makes the weeding process much less laborious. The figure shows the tendency of growth and spread of weeds depending on the thickness of the mulching layer.1. In the absence of a mulching layer weeds occupy 100% of the area of ​​the site.

2. At a thickness of a mulching layer of 3 cm weeds spread only on 22% of the area.

3. The mulching layer of 5 cm inhibits the growth and spread of weeds to 10%.

4. With a mulching layer thickness of more than 7 cm, weed area is reduced to 8%
