The humic acid benefits for soil is obvious.
The functional groups of humic acid are easy to solidify with calcium ion in soil. And then promote the formation of soil aggregates through the physiological action of plant roots. So that the porosity of soil is relatively increased and the permeability is better. Which is beneficial to the absorption of nutrients and normal growth of crops. The acidic functional groups of humic acid can neutralize with the alkaline substances in saline-alkali soil and adjust the PH of soil. So as to achieve the effect of salt and alkali treatment.Read More
