Van Iperen GreenSwitch® Original HG is the first liquid Nitrate fertilizer from organic source, allowing growers to reduce their carbon footprint without changing their cropping system. GreenSwitch® Original is a 2 - 0 - 7 formulation pure and transparent for high-tech greenhouse and open field fertigation. It is produced in our factory in the Netherlands using a proven close to zero Carbon footprint production process certified by the SNK (Stichting Nationale Koolstofmarkt) following the Paris agreement (COP 21).
The GreenSwitch process, based on Pure Green Agriculture Technology, is a circular process contributing to restore the Nitrogen cycle by up-cycling the Nitrogen from manure into a crystal clear nitrate fertilizer. GreenSwitch® Original is suitable for conventional and organic farming. Please check your local regulation for organic farming compliance.
