1.Humic acid combined with chemical fertilizer and inorganic water-soluble fertilizer can reduce the conventional dosage of chemical fertilizer and inorganic water-soluble fertilizer by 10%~20%.
2.The source of humic acid encountered calcium and magnesium ions in the water will rarely produce flocculent precipitation, in order to prevent blockage of drip irrigation holes, in drip irrigation humic acid fertilizer, we should minimize the drip irrigation time, to achieve a small number of times, while ensuring adequate dilution.
3, humic acid is black or dark brown, if the concentration is too high or the degree of atomization is poor when spraying, the water will often leave black spots on the fruit surface and leaf surface after evaporation. If this is the case during picking, rinse with water.

According to the Ministry of Agriculture’s “Standards for Hydrolyzed Fertilizers Containing Humic Acid”, the humic acid raw material must be a mineral source humic acid.
