If any phytopathogens or pests settle in the soil intended for growing seedlings, there can be no talk of obtaining strong and healthy seedlings.
This is the reason why the soil mixture must be subjected to a procedure called disinfection.
Disinfection can be carried out using various methods and means. Thus, such operations as calcination or steaming have proven themselves to be excellent.
However, such manipulations also have a significant downside.
As a result, not only all pathogenic microorganisms and possible parasites die, but also the soil microflora, which means that in this case it is impossible to do without the introduction of biological preparations.
In this regard, many gardeners prefer to do without steaming and calcination, adding preparations based on hay bacillus or trichoderma to the soil 1-2 months beforehand.
Let us remind you: these funds should be contributed separately in order to avoid competition.
Therefore, in order to disinfect the soil, you should choose one thing.
