We are manufactory for production of leonardite humic acid,potassium humate,sodium humate fertilizers since 2000.And our commodities are of high quality.
<o:p> Potassium humate (K-humate) is obtained by alkaline extraction of lignite or brown coal or leonardite and is used commercially as a soil conditioner. 
&nbsp;&nbsp;&nbsp;&nbsp; 
Major Applications 
1) This product can improve the potassium content in soil and accelerate releasing of potassium that’s trapped in insoluble matters. Improving the utilization of fertilisers, it, combining with such elements as N, P and K, constitutes highly-efficient multi-function compound fertilisers.&nbsp; 
2) Potassium Humate alleviates the toxicity of pesticide residue and prevents soil from contamination of heavy metallic ions as well as other harmful matters. 
3) This potassium salt stimulates the growth. The quinoidine and active acids within the product bear strong potentiality of oxidation, which restrains the activities of free radicals and hence, avails the development of the foliage； Potassium, acting on the cell level, facilitates the absorption of the roots and the exchange through the stomata; this element is also a vital constituent of chlorophyllous, speeding up photosynthesis.<o:p></o:p>
