Potassium Humate Description

Potassium humate is humic acid potassium salt ,as an effective organic fertilizer.Can increase utilization of potassium,slow release nitrogen,Activate phosphorus locked inside the soil thus to increase the soil fertility.Can also improve the soil structure, promote crops growth, improve crop resilience, improve crop quality, protection of agricultural ecological environment.

Main Function

  1. Largely increase the efficiency of fertilizers,especially Urea,ammonium sulfate,DAP,MAP.
    Potassium humate could lock the nitrogen in soil and slow release ,also will release the Phosphorus locked by Al+ ,accordingly increase the efficient of fertilizers.
  2. Poassium humate Largely promote the buffering power and fertility of soil by improving the structure.
    In sandy soil ,humic acid will help to increase fertility of soil through its cation exchange capacity to retain water and beneficial micro nutrient .In heavy and compact soil ,Humic acid will work with fungi to construct a crumb structure root to absorb water oxygen and nutrient also improve root penetration.
  3. Potassium humate Neutralize both acidic and alkaline soil to release the beneficial metal ions, thus promote absorption by plants.
    In alkaline soil, beneficial ion and other trace elements can not be absorbed by plants,humic acid can buffer the pH and convert the nutrients and trace elements into absorbable form and promote their uptake by the roots.
    In acidic soil, humic acid will largely reduce the toxins such as the ally aluminum and heavy metals, which will be bonded firmly and immobilized ,thus their toxicity is reduced and phosphate is bonded by aluminum is released.
    In salinalised soil, Salts are split up by the high cation exchange capability, cation (eg.Ca, Mg) are bonded and chelated.
  4. Forster proper environment for soil microbial mass.
    Soil research shows that a place with higher content of humic acid will appear more beneficial microbial mass.Thus these microbial will help to increase the good effect of the soil.
  5. Largely optimized the absorption of beneficial ion by plants thus increase plants growth accordingly increase the yield and fruits quality.
    Humic acid stimulates the membrane of seeds to form a strong roots, which is decisive to increase the capacity of root to take up both micro and macro nutrients. Based on improved structure by humic acid N is largely stored and slow released, P is release from AL +in soil,also other microelement is in the form of easy-available by plants, meanwhile the beneficial fungi is active to produce different kind enzymes. with the above joint effort, the yield will be increased at lease 30%. Enhanced cell assimilation as well as photosynthesis increase the plant’s sugar and vitamin content, thus the quality of their seeds will be largely increased.
  6. Enhance plants’ ability to counter stressed conditions.
    Potassium humate can mobilize K absorption to regulate the stomata open and close on the leaves also promote metabolism, thus increase the plants’ ability under stressed conditions.


  1. Base fertilizer: 5-10kgs/ ha, suggested mix with N, P fertilizers.Mixed with Nitrogen fertilizer: 5% of total blend ie. 5kgs of potassium humate per 100kgs of Urea. Also it depends on the soil condition.
  2. Caution: Before transferring to drip irrigation tank we suggest dissolve potassium humate in a small tank and filtering.


  1. Woven bags with poly bags inside 25kgs net weight
  2. Could also provide according to customer’s requirement.
