Potassium silicate fertilizer is a specialized raw material for manufacturing silicon potassium fertilizer. The silicon potassium fertilizer produced from this material can prevent the evaporation of water in vegetables and fruits, increase sugar content, and play a role in preservation, disease and pest resistance, suitable for various crops. Silicon potassium fertilizer is a new type of fertilizer, in which potassium silicate is one of the main raw materials. The stability of its quality directly affects other blending indicators of the fertilizer. Therefore, choosing a large-scale potassium silicate production enterprise is crucial for the production of silicon potassium fertilizer.
