Humic acid and Fulvic acid analysis
The American Association Of Plant Food Chemist Officials (AAPFCO) has approved a method to determine the fulvic acid fraction of plant and soil amendments for the purposes of labeling.
"The analytical procedure developed jointly by the Humic Products Trade Association (HPTA) and the International Humic Substances Society (IHSS) has been approved by AAPFCO as the only officially recognized procedure for the analysis of humic acids and a specific category of fulvic acids. The procedure has been published in the Journal of AOAC International, a peer reviewed scientific journal, and is currently being reviewed by the International Organization for Standardization (ISO) as a possible international analytical standard."
