  • Nutrients like calcium, sulfur & magnesium are not naturally water soluble.
  • Most powdered lime or gypsum, straight from the mine/quarry, takes multiple years to break down.
  • To ensure “rapid release” of the nutrients the mined product must be ground or pulverized prior to putting it in granular form.
  • MK pulverizes the raw limestone and gypsum very fine so the nutrients are immediately available to the plant once the granular dissolves.
  • Over 70% of our product will go through a 200 mesh screen prior to putting it in granular form.
  • This is what separates MK Minerals from most other suppliers of Limestone & Gypsum. Check the fineness factor to compare.
