Water Soluble Humic Acid Powder 95%

Water Soluble Humic Acid Powder is designed specifically to be mixed with water to produce a liquid humic concentrate. The resulting organic solution is compatible with many liquid fertilizers and micro- nutrients, acting as a chelating agent aiding plants in the uptake and usability of nutrients essential for a crops healthy and productive life cycle.

The Water-Soluble Powder contains the same benefits as our liquid Humic Acid, but with greater costs savings on shipping. Earthcrew carries a micronized version of the powder from a weathered type of oxidized sub-bituminous coal, and a water soluble in a flake sourced from Leonardite (lignite coal).

Both materials are 100% soluble and organically certified for use in organic crop programs.

AGRONOMIC USES: Apply directly to the soil in fall or early spring and as many as 4 to 6 applications per growing season. Always conduct a soil test to determine nutrient levels and make needed amendments to assure good fertility levels in your soil. Water Soluble Humic Acid is an ideal supplement to aid in the effectiveness of your fertilizer program. Application rates will vary depending on soil conditions, plant type, nutrient requirement and application method. Consult your local Ag Extension Agent for more information for your specific application.

MIXING INSTRUCTIONS: Mix 1lb of Water Soluble Humic Acid into 1 gallon of water (1kg into 5 liters) to create a Liquid Concentrate.

SHAKE WELL prior to further diluting/mixing. When mixing with water, fill container half full, then add Liquid Concentrate to the remaining water. If mixing with pesticides, dilute Liquid Concentrate with water prior to the addition of buffering agents and pesticides. DO NOT tank-mix with carbonate-based pesticides, as efficacy will decrease. Follow all directions and precautions on pesticide labels prior to mixing with Liquid Concentrate. Ensure adequate agitation in all situations. DO NOT mix Liquid Concentrate with calcium nitrate, phosphoric acid, zinc sulfate or other solutions with a pH of less than 6.5

DIRECTIONS FOR USE: Proper timing, rate, and placement of Water Soluble Humic Acid is important for desired results and highly dependent on stage of crop growth, soil fertility levels and environmental conditions. If unsure of application rates for your specific soils, consult your local Ag Extension Agent.
