Sulphur-Based Fertilizer Composition with Humic Acid Content

---

Abstract

---

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.
