Utilisation

A teafűből készült komposzt hatékony természetes növényvédőszer különböző növényi kórokozókkal szemben, mint például a szürkerothadás kórokozója.
Szennyvízből réz és ólom adszorbeálására használják a hulladék teafüvet.
A fekete teán fermentált mikrobiális közösség (gombák) az arzén eltávolítására képes a talajvízből.
Napégés és rovarcsípés kezelésére is alkalmas, puhítja a bőrt. A hűtőszekrény és konyhai felületek szagtalanítására alkalmazható, esetleg kárpitok felfrissítésére.

Feltételezhetően nincs káros hatása.

Would it be suitable for soil reclamation in general?
Yes
Justification, references

Mivel magas a nitrogén és szerves anyag tartalma, jó talajerő utánpótló.

Vermikomposztálva a talajban növeli a szervesanyagtartalmat, humusztartalmat.

Would it provide sufficient amounts of special nutrients to the soil?
Yes
Justification, references

Mivel magas a nitrogén és szerves anyag tartalma, jó talajerő utánpótló.

Would it suffice as an additive to growing media?
Yes
Justification, references

Mivel magas a nitrogén és ásványi anyag tartalma, jó talajerő utánpótló.

Would it improve the structure of compacted soil and/or contribute to soil crumb formation of poorly structured soils?
Yes
Justification, references

Nagy szerves anyag tartalmának köszönhetően javíthatja a talaj szerkezetét, ezáltal csökkentve a tömörödést.
A talajba helyezve növeli a porozitást és a talajrögök méretét csökkenti. A vizsgált növények növekedését elősegítette.
