International standard ISO 19822 into Humintech’s quality control.

After taking effect of newly approved ISO standard 19822 "Fertilizers and soil conditioners — Determination of humic and hydrophobic fulvic acids concentrations in fertilizer materials", and the decision of the European Committee for Standardization (CEN/TC 455) to adopt this standard also for humic and fulvic acids based biostimulants, Humintech has introduced this analysis standard for its quality control.

The adoption of the new ISO standard has become very topical, especially regarding the confusion to the currently marketed "fulvic acids" derived from plant materials. With the introduction of ISO 19822, there is now an effective tool available to distinguish between humic substances and other industrial by-products, preventing confusion on the markets like in the past.

Due to this transparency, Humintech offers clients the opportunity to choose for quality controlled real humic substances based products for all kind of applications.
