Humic acid and potassium humate difference
Humic acid is also called humic acid raw powder, which is essentially screened. The essence of leonardite is organic matter. The essence of organic matter is humus. The essence of humus is humic acid. But limited by the raw material itself. Humic acid is insoluble in water. This leads to the disadvantage of difficult decomposition and slow effect in the process of agricultural application.
According to the characteristics of humic acid powder which is soluble in alkaline solution and insoluble in water and acid solution. We activate humic acid with strong alkaline substances such as sodium hydroxide, potassium hydroxide or ammonia water. The final product is humate salt. Which in turn is called sodium humate, potassium humate and ammonium humate. This activated humic acid product has the characteristics of high water solubility. High activity and high chelation. And is mainly used in flushing, drip irrigation and even sprinkler irrigation. Compared with humic acid raw powder, the effect of activated humate fertilizer can be seen in one week. Including the improvement of soil water retention performance, the length of crop root and so on.
