Khumic - The Largest Humic & Fulvic Products Factory In China. Reliable Quality & Competitive Prices!



KHUMIC-100 (Potassium Humate Powder/Flakes organic fertilizer)is 100% water soluble Humate salts, extracted from young active natural leonardite, it is a high quality plant growth stimulant and soil conditioner, can be applied on all plants. It is ideally suitable for the application mixing with granular fertilizers, such as Urea. With prominent effect to release the locked phosphate by some ion such as Fe³+, Al³+, also can slow-release nitrogen fertilizer to promote the function of NPK fertilizers.

Functions & Benefit:

1) Water soluble potassium humate can improve the structure of soil; increase the buffering power of soil. Optimize N,P,K absorption by plants.
In light, sandy soils, humic acid increase the cation exchange capability to retain nutrients and water, importantly to magnify the ability of root to take up nutrients. In heavy and compact soils, working with fungi to create a crumb structure for better water oxygen and nutrients intake and improved root penetration.

2) Neutralize both acidic and alkaline soils, regulate the pH-value of soils, with the prominent effect in alkaline and acidic soil.
Under alkaline conditions humic acid can buffer the pH can convert the nutrients and trace elements into absorbable form and promote their uptake by the roots, as under high pH value many essential nutrients and trace element are not in plant-available form. In acidic soil can largely reduce the toxins such as the ally aluminum and heavy metals, which will be bonded firmly and immobilized by humic acid, thus their toxicity is reduced and phosphate is bonded by aluminum is released. Salinalised soil: Salts are split up by the high cation exchange capability cation (eg. Ca, Mg) are bonded and chelated. The high osmotic pressure within the root area is largely reduced.

3) Stimulate plant growth, increase the yield and quality.
Stimulate the membrane of seeds as well as the metabolic activities and thereby increase the germination rate. Increase the capacity of root to take up nutrients (N, P, K + Fe, Zn and other trace elements) as these elements is easier to be converted into forms available to plants. Accordingly, the yield will be increased up to 30%.Enhanced cell assimilation as well as photosynthesis increase the plant's sugar and vitamin content.

4) Potassium_humate can reduce nitrate leaking into the groundwater and protect the underground water.
Humic acid binds the nitrate and keep it around the root zone, in this way drinking water is better preserved.

5) Humic acid water soluble potassium humate can increase the effectiveness of herbicide, pesticide and fungicide, immobilize or reduce their harmful residues.

6) Stabilize nitrogen and improve nitrogen efficiency (ideal as an additive with urea). Complexes phosphate to reduce lock-ups (ideal as an additive with DAP/ MAP, etc).

Direction for use:

1)Foliar spray: 0.5-1.0kgs/1000kgs water, spray the plant till the leaves are wet each time,at least 3 times during crop cycle;

2) Root Flushing/Irrigation/Fertigation: 2.0kgs/1000kgs water, 35-70kgs/acre apply alone or stir well with normal NPK and apply the solution before seeding or between the plant growing, at least 3 times during crop cycle;

3) Seeds Soaking: 2kgs for 1000kgs seeds.


25kgs/Kraft Paper Bag, or,customized packing is available.
