Brief concise description explaining the innovation
Szabványosított módszer
Typical (recommended) application of the method
Talaj minőségének jellemzését szolgáló kalciumkarbonát meghatározás. A mérés 0,04 és 85% kalciumkarbonát-tartalom közötti érték meghatározásra alkalmas.
Limits of the method
Kén-vegyületek a talajban a H2S felszabadulása miatt pozitív hibát okoznak.
Detailed Protocol
A légszáraz talajra 10%-os HCl-t öntünk zárt térben, a keletkezett CO2 térfogatából számítjuk a talaj CaCO3 tartalmát.
