SOLUBLE (100%)

Diamond Grow ® 100% soluble organic Humi[K] WSG (Water Soluble Granule), is the latest addition to the Diamond Grow® product line. After many years of research and product development, our patent pending Humi[K] Granulation Process was in full operation early 2014. Humi[K] WSG is produced from our Humi[K] WSP, which is 100% spray dried powder that can be difficult to handle in certain applications. Our 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 as irrigated. Humi[K] WSG was specifically designed for three distinct functions: Rapid 100% solubility, ease of use and dry broadcast application. Diamond Grow® Humi[K] Granules are mirror image of our Powdered Humi[K], with all of the same features and benefits.

Typical Analysis:

Potassium 12%

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.  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.

Organic Wet Chemistry Activation:

Functional Humate Groups

MIXING INSTRUCTIONS:  Mix 1lb (0.45kg) of Humi[K] WSG into 1 gallon of water to create a Liquid Humi[K] Concentrate.

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 6.5

DIRECTIONS FOR USE:  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.  If unsure of application rates for your specific soils, please consult your local Ag Extension Agent
