The purity of peat is the safety of the cover soil and the protection of fungi from infection by pathogenic microorganisms (/eng)

The first stage of creating a safe cover is the correct extraction of raw materials for its production.

When harvesting peat it is necessary to remove the first 0.8 -1 m of the surface layer of development, since it contains a large number of pathogenic organisms that can very quickly infect the entire growing farm, and get rid of they will make it quite difficult.

Production peat substrate for growing champignons should be geographically divided into main functional zones:

• Site or hangars for storing raw materials;
• The production itself is divided into dirty (preparation of raw materials) and clean zones (formation of the substrate and packaging in big bags)
• Separate warehouses for short-term storage and release cover soil.

Just like for people, sanitation is an integral part of production. If you carry out preventive measures during the production of cover soil, follow the rules of hygiene and technology, then diseases and pests will not further affect the yield of champignons. Almost any illness can be avoided with proper organization of work at the enterprise:

1. Regular disinfection of premises.
2. Washing with a strong jet of water and disinfection of machines used for loading, unloading and transportation of peat, equipment for preparing the coating mixture.
3. Correct organization of the sequence of work in production.
4. Staff training.
5. Timely detection and proper isolation of the disease.

An important problem is the storage of pokrovka. As easy as it is to obtain a covering soil that meets hygienic requirements and of good quality, it is so difficult to store it. It should be remembered that in pokrovka infections easily develop, and pathogens can develop without the presence of champignon mycelium, in contrast to raw high peat with acidic and very acidic pH. </ em>Pokrovka can be stored in bags longer. However, it should be remembered that during storage it loses moisture and moisture capacity, and these processes occur differently in each bag.

With the increasing quality of compost, the use of additives and mycelium with high yield potential, the role of safe on­blood soil increases significantly.
