Potassium Humate Fine Powder is the potassium salt of humic acid made from high grade Leonardite, which is not only a more readily available potassium fertilizer but also has all benefits from humic acid both to soil and to plant, such as soil conditioning, nutrients uptake improving etc. In addition, it has wider applications from soil application, seed soaking, root soaking to fertigation due to highly water soluble.

Nutritionally. As a good fertilizer enhancer, sharply increase the utilization efficiency of potassium exists in plant itself and in soil, as well as to nitrogen, phosphorous and other mineral fertilizers in soil. 

Physically. As a soil conditioner, promote good soil structure formation, increase the capacities of water holding and cation exchange and improve aeration condition. Besides, these benefits will be further helpful for plants to resist drought stress.  

Chemically. As chelating and buffering agents, respectively helps retain water soluble inorganic fertilizers, preventing them from leaching, and protect plants from drastic change in PH.

Biologically. As food sources, establish a desirable environment for microorganism development. Stimulate seed germination and viability, and root respiration, formation and growth. Thus increase crops yield and quality.

>Recommended Applications

As ground fertilizer:

It’s the major application of this product which can be applied alone or combined with Nitrogen and Phosphorus before seeding or planting. It’s particularly suitable for the following types of soils:

1) Alkaline soil with low iron content;

2) Sandy soils with low organic (humus) content

3) Acid podzol soils with low humus content, simultaneously liming to soil

4) Saline soils; 

5) Lime soils.

Soil application: 

8~12 kg/ha; or blend Potassium Humate with normal N.P.K base program with 3% of total amount of N.P.K

Foliar Spray:

Dilute 0.5~1 kg Potassium Humate to average 100 liters water or other functional solutions. Apply 3~4 times, at intervals of 20 days during the growing season.

Seeds Soaking: 

2~3 kg Potassium Humate for 1 ton seeds or dilute to 0.01~0.03% and adjust pH to 7.2~7.5. The soaking time varies from 12 hours to 24 hours with the thickness of seeds skin, hygroscopic capacity of seeds and the surrounding temperature. The suitable temperature for seeds soaking is about 20°C.


Add it to irrigation water with the ratio of 8~12 kg/ha
