Disclosed herein are fertilizer compositions with enhanced sulphate release, methods of making the fertilizer compositions and methods of using the fertilizer compositions. The disclosed fertilizer compositions combine elemental sulphur with small amounts (relative to the sulphur) of humic acid to enhance delivery of sulphates to soil. The humic acid is added as a humic additive, which may comprise 40% or more humic acid. In many embodiments, the presence of small amounts of humic additive enhances the release of sulphate from soil containing the fertilizer composition from about 1.5- to 4-fold over fertilizer compositions lacking the humic additive.

Sulphur-based fertilizer composition with humic acid content

A fertilizer composition is provided that includes boron and sulfur. The fertilizer composition can be a controlled release fertilizer that includes elemental sulfur, an anhydrous boron-containing compound, and a swelling material. The fertilizer composition can be produced by mixing molten elemental sulfur with the anhydrous boron-containing compound and cooling the mixture.
