Bio Treat Humate is a powerful stimulant for biological activity in the soil and contains Humic, Fulvic and Ulmic acids.  Bio Treat Humate feeds the soil microbes which then release nutrients such as nitrogen, phosphorus and other trace elements.

  • Humic Acid allows the plants to extract nutrients from the soil easily.
  • Fulvic Acid assists plants in withstanding stresses caused by dry weather, cutting and pests.
