2. Caolinite Clays 1/1
   • Need foliar UltraGrowth on existing plants
   • Need solid UltraGrowth on soils
   • May need foliar mineral spray
   
   
3. Bentonite Clays 2/1
   • Hign Sodium content
   • in water discharge zones
   • causes reverse osmotic effect
   • creates a hard pan layer in soil
   • Need UltraGrowth and Calcium based fertilizer
   • change SAR (Sodium Absorption Ratio)
   • must balance microbial population, chemistry, bio chemistry, and minerials
   
   
4. Montmorillonite Clays 2/1
   • best clays, very high in minerals
   • problem minerals are mostly in unavailable form
   • UltraGrowth solid in soil important
   • vegetation needs UltraGrowth liquid
