Purebase Humate Advantage(TM)

prod-purebase-humatePurebase Humate Advantage(TM) is derived from a proprietary deposit of oxidized lignite shale. The combination of humic and fulvic acid in approximately a 4 to 1 ratio, coupled with a unique cross section of plant macro and micronutrients, allow Purebase Humate Advantage(TM) to simultaneously improve soil quality as well as buffer high pH conditions. Products containing humic acids, may increase uptake of micronutrients.


  • Increases nutrient uptake
  • Soil microbial activity and diversity is increased
  • Buffers soil pH and increases CEC (Cation Exchange Capacity)
  • Improves soil structure and water holding capacity
  • Chelates metal ions in alkaline conditions
  • Provides nitrogen, phosphorous, iron and sulfur
  • Contains 36% humic acid, 9% fulvic acid, and 32% organic carbon
  • Available in granular grade and micronized solution grade, in bulk tote, container load, or palletized 50lb bags.
