Title:
LIQUID HUMIC ACID EXTRACT
Document Type and Number:
WIPO Patent Application WO/2021/117755
Kind Code:
A1
Abstract:
This liquid humic acid extract does not form precipitates when combined with a liquid fertilizer containing at least one of Mg, Fe, Zn, and Mo and having an electric conductivity of 90 ms/cm or more. The liquid humic acid extract contains a humic acid having a mass average molecular weight of 100-1,200 and has a total organic carbon concentration of 15,000-25,000 mg/L and a pH of 0.5-4.0. Preferably, the liquid humic acid extract contains a humic acid having a mass average molecular weight of 100-1,200 and has a total organic carbon concentration of 15,000-25,000 mg/L and a pH of 0.5-4.0. With the present invention, it is possible to provide a liquid humic acid extract that is less likely to form precipitates and can increase the yield of crops.
