Absolutely NO FILLERS!

100% soluble organic Humi[K] WSG (Water Soluble Granule). After many years of research and product development, the patent pending Humi[K] Granulation Process was in full operation early 2014. Humi[K] WSG is produced from Humi[K] WSP, which is 100% spray dried powder that can be difficult to handle in certain applications.

The Humi[K] Granulation technology allows us to offer the same 100% solubility in a granule form. Humi[K] WSG can be used in many applications such as dry broadcast spreading, blending/mixing with fertilizer, or liquefied for liquid application. Humi[K] WSG also has time release properties when applied dry, slowly dissolving over time. Humi[K] WSG was specifically designed for three distinct functions: Rapid 100% solubility, ease of use and dry broadcast application. Humi[K] Granules are mirror image of Humi[K] WSP, with all of the same features and benefits.


AGRONOMIC & HORTICULTURAL 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.  Humi[K] WSG is an ideal supplement to your fertilizer program.  Application rates will vary depending on soil conditions, plant type, nutrient requirement and application method. Consult your local agronomist or Ag Extension Agent for more information for your specific application.


DIRECTIONS FOR USE: WSG can be mixed with Dry Fertilizers and also "Inducted" into spraying solutions. Proper timing, rate, and placement of Humi[K] WSG is important for desired results and highly dependent on stage of crop growth, soil fertility levels and environmental conditions.

Activated Functional Groups

Mix the desired rate of dry granules into your dry fertilizer mix, or blend the same application rate into your spray mix. 

SHAKE WELL prior to further diluting/mixing.  When mixing with water, ¬≠fill container half full, then add Liquid Humi[K] Concentrate to the remaining water.  When mixing with pesticides, dilute Liquid Humi[K] 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 Humi[K] Concentrate. Ensure adequate agitation in all situations. DO NOT mix Liquid Humi[K] Concentrate with calcium nitrate, phosphoric acid, zinc sulfate or other solutions with a pH of less than 6.0.


APPLICATION INSTRUCTIONS:  4 - 10 lbs/gallons of Humi[K] per acre per application. Split apply throughout growing season for maximized results.
