Humic acids, also known as humic substances, consist of humic and fulvic acids, and are produced in the process of drinking water discolouration. They are natural substances, degradation products of organic matter under oxygen-poor conditions. Humic acids are extracted from the water by using so-called ion exchangers, which are periodically flushed (regenerated) with salt water. The residual product consists principally of water, salt and humic acids.
A unique technology is used to separate the water, salt and humic substances from each other; they are then 100% reused. Pure humic substances are obtained in liquid form, with a colouration ranging from yellow to brown, depending on the concentration. Currently, humic acids are produced at a single location in the Netherlands, namely, at the Vitens water company. But it is expected that they will also be produced in the near future at other Dutch and Flemish locations.
Humic acids render agricultural land fertile: they give the soil structure, so that it can retain more water and nutrients, and they improve crop root growth, serve as food for microorganisms, and improve the absorption of minerals. The sustainable application of humic substances produces higher crop yields and simultaneously reduces the need for artificial fertilisers and phosphorus.
Both AquaMinerals and the humic acid producer are GMP+ certified, which means the substances can be marketed in the animal feed sector. Initial research indicates that feeding them to piglets produces animals that are healthier looking and grow strongly.
