Ask if there are any current standards for biohumic acid fertilizers

Only standards for water-soluble fertilizers containing humic acid

What is biological humic acid? How is it different from humic acid? Are the production methods special?

http://bbs.hcbbs.com/viewthread.php?tid=407190&extra=page%3D1&frombbs=1 I have uploaded a humic acid agricultural fertilizer standard here

It seems that it should be the same, because all humic acid production processes involve biological participation, but the time and procedure of biological participation are different. If there is really a difference, it should be distinguished by the amount and importance of biological participation in the production process.

Not the same. Generally speaking, HA refers to humic acid, which means lignite, peat, etc. are used as raw materials. The raw materials are probably crushed and then added to the KOH treatment. The water solubility is poor and the fertilizer effect is long-lasting. However, it should be said that if it is a pure humic acid fertilizer, the fertilizer effect is very average. The ones on the market now are generally made by mixing humic acid fertilizers with NPK or something like that. However, in order to improve the water solubility, some people now add complexing agents and the like, and the effect is said to be good. And if it is biological fulvic acid, or biochemical fulvic acid, some people call it BFA or FA. The raw materials are organic matter, such as straw, livestock and poultry manure, etc., which are fertilizers processed after biological fermentation. The fulvic acid made by this method has much better water solubility. However, mass production is far less efficient. This post was last edited by ragna78 on 2009-4-10 15:08 ]
