Organic Fertilizer for Micronutrient Uptake

Organic Micro Hume is a micronized solution grade, dry powder which may increase micronutrient uptake. It may be applied in diluted form as a foliar spray or as a soil drench, or it may be applied directly to the soil. Note: when used as a foliar spray, micro hume may leave dark spots on the leaves.

45% Humic Acids derived from leonardite shale.

  • To use as a solution, add to water and stir or shake well. Re-agitate the suspension if the tank mix is not applied within 5 minutes.
  • The addition of a kelp extract, such as PVFS Organic Liquid Kelp, and a fish product, such as PVFS Organic Liquid Fish, is highly recommended.
  • Micro Hume may be combined with most fertilizers or trace minerals. If mixing with other products, always test for compatibility and do a small trial spray to check for phytotoxicity.

Customer Reviews


I used this as a foliar spray on my veggies along with Seabird Guano and Liquid Kelp. After the spray, they have all perked up and look better than ever!
