There is an explanation that Hak is an English humic acid potassium salt; Humic Acid potassium; Humi acids,potassium salts abbreviation? The Chinese name is potassium humic acid, humic acid potassium is a polymer heterogeneous aromatic hydroxy carboxylic acid salt, the appearance of black particles or powdered solids, is a refined brown coal after the use of Koh liquid reaction to extract the product, soluble in water, alkaline, containing carboxyl, phenolic hydroxyl group and other active groups.
Both of these fertilizers are fertilizers that contain potassium humic acid, then someone asked, this compound fertilizer contains no potassium (K2O), small series can be sure to tell you that there is no, there may be some dealers in the cheat farmers do not understand, a random explanation, said this fertilizer good, there are 19-19-19, there are 18-18-18 of , the price is low, peasant figure cheap psychological mischief to buy.
I don't know how to eat, as long as it's cheap. Similar to the concept of a lot of fertilizer, I will not say, to buy fertilizer to buy cost-effective, not cheap, to understand a penny a penny of the truth.
Here is a talk about the role of potassium humic acid, high quality humic acid potassium is an efficient organic potash fertilizer, potassium hydroxide is not included, because humic acid is a bioactive agent, which can increase the content of available potassium, reduce the loss and fixation of potassium, increase the uptake and utilization of potassium in crops, improve soil, promote crop growth, To improve crop resilience, improve crop quality, protect the agricultural ecological environment and other functions.
It is mixed with urea, phosphate fertilizer, potash fertilizer, microelement and so on, and can be made into high efficiency multifunctional compound fertilizer. In addition, humic acid potassium can also be used as an oil drilling fluid treatment agent, mainly to prevent the wall collapse of the role.
However, China's humic acid potassium market is very disorderly, the price is measured, some manufacturers use of humic acid potassium is what we call coal head, pulverized coal. Low price effect is not, so small series, farmers must not buy cheap humic acid potassium products.
Buy chemical fertilizers to buy plants, manufacturers, have the strength of the factory fertilizer, buy cheap fertilizer is: A mu save a few yuan of money, per Mu yield minus 130. Knowing that small greed on the big, but also bold to experiment. Slack to learn more, never to be deceived.
