  • a portion (48%) of quick-release water-soluble potassium without the harsh effect of potassium chloride on some sensitive plant roots
  • a beneficial fast-acting liming effect and lift in soil pH on the soil solution which a  to benefits soil biology and chemistry
  • high level of available amorphous Silica (SiO2) – benefitting grain crops and pest and disease resistance
  • a more beneficial form of potassium compared to other forms such as synthetically produced potassium
  • a vital supply of Potassium to assist with a plant’s general nutrient absorption
  • improvement in photosynthesis, respiration, transpiration, disease resistance and enzyme activity
