Abstract:
A method for reducing water repellency within sandy areas, soils, or areas including both sand and soil comprising the application of a soil additive formulation to a target area comprising sand, soil, or both, wherein said soil additive formulation comprises at least one humic acid redistribution compound selected from the group consisting of at least one hydroxy, alkoxy or C1-60 alkyl, alkenyl, or alkaryl succinic acid or anhydride mono- or di-cation salt resulting from reaction with a metal or amine functional neutralization salt, at least one C4-60 branched or unbranched diacid mono- or di-cation salt resulting from reaction with a metal or amine functional neutralization salt, at least one polycarboxylic acid derivative salt, and any mixtures thereof, and from 0-99% by weight of at least one compound that actively lowers the surface tension of humic acid waxy coatings from hydrophobic sand particles.
