Low-Energy Innovation for Low-Carbon Agriculture
What makes GreenSwitch® Potassium process sustainable?
Unlike conventional Potassium Sulphate (SOP) production that relies on energy-intensive, high-temperature thermal processes, GreenSwitch® SOP is manufactured through an innovative low-temperature and low-pressure Glaserite process. Here's how it works:

GreenSwitch® Potassium Sulphate Horticultural Grade, the final product
GreenSwitch® Potassium Sulphate HG is a high-purity, fast-dissolving, and fully water-soluble Potassium fertilizer. It is produced through a low-temperature, low-pressure process that requires less energy than conventional production methods, contributing to a reduced carbon footprint.
Suitable for greenhouse and open-field fertigation as well as foliar application, it is non-caking and ideal from fruit or tuber development through maturation, supporting high-quality yields.
GreenSwitch® Potassium Sulphate HG combines reliable crop nutrition with a more energy-efficient production process. By using GreenSwitch® fertilizers, growers reduce their carbon footprint and switch to sustainable high-tech agriculture.
