Description

solvable sodium humic acid, potassium humic acid, ammonium humic acid etc. series products manufactured from raw materials of lignite, weathered coal, peat (turf), also you can produce nitro-humic acid, sulfurmethylated humic acid, cinnamon humic acid, fulvic acid and monovalent metallic salt from humic acid which is as raw material with modified method. This series of products typically involve HA ****0%, pH ***0, water insoluble substance ****0%. The highest concentration of liquid HA is ****0%, after temperature <*0&#***1; reached it will be stiff flow jelly. HA has multiple functional effect for changing soil&#****9;increasing fertilization&#****9;impulse growth promoting&#****2;fighting droughts and ant-icontrary, improving quality etc.&#****2;however, the coal humic acid has high molecular weight, not anti-acid and bivalent metal ion. In the case of hard water, it will be precipitation by flocculation, this brings serious influence for promoting HA application.
