Brief concise description explaining the innovation
A részletes protokoll a MSZ 21470/52:1983-ban található.
A módszer nem tartalmaz újdonságot.
Typical (recommended) application of the method
Talaj jellemzése a szervesanyag-tartalom alapján.
Detailed Protocol
Légszáraz és homogenizált talajból bemérés, a dikromát és a kénsav hozzáadása után 24 óra ülepítés majd a tiszta fázis fotometrálása 590 nm-en.
Egy másik szabvány ugyanezt a módszert hulladékra írja le: MSZ 08-0210-77.

Strengths
Hagyományos, jól bevált talajvizsgálati módszer. Egyszerüsített szervesanyag/humusz meghatározási módszer.
Weaknesses
Nem különbözteti meg holt szervesanyagot és a humuszt. Nem ad infromációt a humuszfrakciókról.
Possibilities
Bármilyen laborban vagy helyiségben elvégezhető, helyszínre is telepíthető.
Threats
Nehezen interpretálható.
