I. DESCRIPTION
Potassium Humate is a humic acid potassium salt, in powder and flake form, mainly used in agriculture. Highly soluble in water (see the TDS for each grade), with pH 9–10, in powder, crystal, flakes form. Usually, we suggest to mix with Urea, DAP, MAP to use as irrigation fertilizer.
2. APPLICATIONS
- Soil application as a humic and potassium source
- Fertigation and liquid fertilizer production (dissolve before use)
- Blending with compound and bulk-blended fertilizers (e.g. urea, DAP, MAP)
- Potassium humate is not a pesticide or bactericide and does not control soil-borne diseases.
3. HOW TO USE POTASSIUM HUMATE
- Dissolve before use in fertigation and liquid fertilizer production.
- Can be blended with compound and bulk-blended fertilizers (e.g. urea, DAP, MAP).
Application rates depend on crop, soil and formulation. Please contact us for technical guidance and run a small-scale trial before large-scale use.
4. PRECAUTION
- Before transferring to a drip irrigation tank we suggest dissolving potassium humate in a small tank and filtering.
5. POTASSIUM HUMATE PACKAGE
- Woven bags with poly bags inside 25kgs net weight,
- Could also provide according to customer’s requirement.
