ImerFert Z european zeolites are premium-quality, natural clinoptilolite zeolites produced at our Beli Plast operation in southern Bulgaria from ore containing over 85% clinoptilolite.

Contact our EMEA teams for more information about this grade.

In Europe, we offer 3 silicon-donor products, each designed for a specific application:

  • ImerFert WSi L11: a micronized grade specifically designed for liquid biostimulant and specialty fertilizer suspensions
  • ImerFert WSi F05: the ideal bulk density for all solid fertilizer formulations
  • ImerFert WSi G87: appropriate sized particles which can be easily added to growing substrate blends 

Si extraction rates for various minerals
As shown below, wollastonite, which is a calcium silicate, offers the most available form of Si among natural minerals.
It  also provides a slow release source of calcium. Si was extracted using the CaCI2 method and determined by ICP.
