BioSevia

has several essential qualities:

   * It is a complete plant food.
    * Its specific composition, and its excellent solubility, make it easy for plants to assimilate.
    * It is efficiently applied in fertigation and drip irrigation.
    * It contains fulvic acid and humic acids which improve soil conditions and enhance the plant’s absorption capacity.
    * It brings a sweet, pleasant taste to your crops.
    * … and it works in hydroponics!

BioSevia is a “bioponic” nutrient
BioSevia gives perfect results in soil, of course, but it has the exceptionality to work beautifully in hydroponics too, be it with bare roots, or on substrates. Indeed, not any nutrient is adapted to this type of growing. Generally, organic nutrients are formulated in order to slowly decompose in soil so, when in water, some of their elements will rot and release some quite unpleasant smells. Finally, they would clog the filters and injectors.

To be bioponic, a nutrient must be liquid or perfectly soluble. It must be rapidly degradable and readily available to the plant. BioSevia fits to all these conditions.

BioSevia is a nutrient that can be used in organic cultivation. It applies to the European regulation on organic agriculture N°2092/91.

BioSevia is certified by Qualité France SA, an official institution approved by the French government and the European Community, which gives it official recognition in all European countries.
