Abstract: Aqueous liquid formulations contain one or more anionic polymers, a high concentration of boron compounds, and a boron dispersant or solvent. The compositions are operable to maintain the boron content thereof in stable dispersion for at least 72 hours. The dispersant or solvent is selected from saturated aliphatic diols, glycols, hydroxyl-rich compounds, alpha-hydroxy acids, and mixtures thereof. Preferred polymers include dicarboxylic repeat units and optional sulfonate repeat units. The formulations have heretofore unattainable high boron contents, and are useful in agricultural contexts.
