Product Description

Product Description
European food grade potassium metabisulfite is a natural potassium fertilizer that contains
abundant potassium elements, which can be directly absorbed by crops. In addition, the
exchange reaction between sulfate ions and cations in the soil can change the composition
of ions in the soil, making it more porous and reducing the evaporation of water in the soil.
