Definition : 1) Humus: is a kind of organic matter. It is remains of animals and plants degraded by microorganism in soil. 2) Humic Acid: is a permanent humic substance with macromolecular structure. Which is insoluble in water but alkali. 3) Humate : in another word is humic acid salt, when humic acid combing with K2O or NaOH convert into a kind of sult can be soluble in water. 4) Fulvic acid : fulvic acid is humic acid of lower molecular weight and higher oxygen content than other humic acid. 5) Fulvate : we also call it fulvic acid salt . There contain some trace elements like K2O, N, Fe.... Etc. How humic acid into fulvic acid ? Humic acid is belong with acid family, which means insoluble but dilute alkali, sodium hydroxid or potassium hydroxid alkaline agents transforms it into water-soluble salts,like sodium and potassium humate. Meanwhile hydrogen atoms in carboxy and hydrogen group are replaced by alkali-ions. Atfer that , strongly acidic combing with humic acid salt to be fulvic acid. The function of Humic Acid: 1) Improve the structure of soil . For light and sand soil, it can retain water nutrient . For heavy and compact soil, working with fungi to create a crumb structure for better water oxygen and nutrients intake and improved root . 2) Adjust PH value of soil, it can neutralize both acidic and alkaline soil . 3) Stimulate plant growth, increase the yield and quality. 4) Reduce nitrate leaking into the groundwater and protect the underground water. 5) Increase the effectiveness of herbicide pesticide and fungicide, immobilize or reduce their harmful residues. The function of fulvic acid : 1) To stimulate seed germination 2) To promote development 3) To improve the structure of the soil and to adjust PH of soil. What`s the difference between humic acid and fulvic acid ?

1) Humic acid is macromolecular structure,which are insoluble in water but dilute alkali; Fulvic acid is lower molecular weight and higher oxygen content than humic acid. Which is soluble. 2) C.E.C of fulvic acid is more active than it of humic acid . What`s the difference between Nitro Humic Aicd and Humic Acid ? When Humic Acid react with H2No3 to be Nitro Humic Aicd , PH about 3.0- 5.0, this process can improve CEC.
