钾Humate

Potassium humate Potassium humate (K-humate) is obtained by alkaline extraction of lignite or brown coal or leonardite and is used commercially as a soil conditioner. Major Applications 1) This product can improve the potassium content in soil and accelerate releasing of potassium thats 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.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.Specifications Appearance black amorphic powder, black pellet or black granule with metallic colour Composition humic acid 40-80% Fe0.45, K(calculated in potassium oxide) ≥11.5 moisture≤15% Mesh 40-100m /1-5m Solubility easily soluble in water, water-solubility≥85% pH value 8-11
