A well-known fact is that as the soil is used, the soil is not only depleted, but also exposed to infection by various fungi and bacteria. When using such a plot, the gardener may notice a deterioration in the growth and development of plants, as well as their low yield. You can cope with this phenomenon, you just need to know how to decontaminate the soil in the garden.
Now there are three main methods of disinfection - chemical, agrotechnical and physical. Let's consider each of them.
Physical method of soil disinfection
Thinking about what to decontaminate the soil in the fall, pay attention to steaming, capable of killing the causative agents of plant and insect diseases. It is produced in mid-November. The soil is covered with a heat-resistant film and processed with steam, the source of which can become a steam boiler.
Agrotechnical method of soil disinfection
This method, by the way, is often used by the owners of vegetable gardens, sometimes without knowing it. First, it consists in the alternation of cultures. For example, after the legumes are planted onions or garlic.
Secondly, it makes sense to plant plants in the early spring that disinfect the soil. For example, white mustard and winter rye are not only able to saturate the earth with nitrogen, but also to neutralize, accumulating in the roots of alkaloids.
Chemical method of soil disinfection
With this method, a chemical preparation is introduced into the ground, which can destroy pathogens of fungal and bacterial diseases of vegetable crops.
Very often experienced gardeners use Carbathion. This is a broad-spectrum remedy used in the fight against fusariosis, wicked, horse rot and black leg. This is just the substance, than it is possible to decontaminate the soil before planting for a minimum of 30 days. The concentrate is diluted
As for what can be decontaminated soil in autumn, then the mixture of lime and copper sulfate is optimal for this purpose. For every square meter use half the glass of substances. They sprinkle the surface of the earth, and the site is then dug to a depth of 20 cm.
A good result is given to biological preparations, for example, Fungistop. They spray the soil in the form of an aqueous solution, which is prepared from 350-500 ml of the product itself and a bucket of water. After such treatment, the infected area is dug to the full depth of the bayonet bayonet.
