This natural fertilizer (described in Secrets of the Soil as rock dust) is actually an ancient deposit of aluminum silicate clay and marine minerals. In use for over 50 years as a source of available potash (0.2%) and over 70 trace minerals, including calcium (1.8%), sodium (0.1%), and magnesium (0.5%).

  • See the attached guidelines for application rates.
  • If using Azomite as a foliar spray make sure there is adequate agitation in the spray tank.
  • If using through an irrigation system, make sure there is good agitation in the tank, such as an agitation machine like a gypsum machine at the front end of the trickle system, and proper screen and nozzle sizes. Both the spray and irrigation rates are 3-5 lb/acre with each application.
