Abstract
The present application provides a humic acid-containing powder, wherein the compression degree is 5 to 20. The compression degree is a value calculated by the formula {(ρ A -ρ A ) / ρ P} × 100, when the loose bulk density of the powder is set to ρ P , and the tapped bulk density of the powder is set to ρ P . The humic acid-containing water obtained by dissolving or dispersing the humic acid-containing powder in water is preferably used for improving soil or promoting plant growth.
