How long does it take for elemental sulfur to become available in the soil?


In order to become available to plants, elemental sulfur (ES) first needs to oxidize in the soil, a process governed by several factors: size of granule, hardness of granule, soil temperature, soil moisture, soil biological activity. With the granular forms of ES in today’s market, such as ES-enriched phosphate products and, particularly, ES-bentonite pastilles, the amount of ES oxidized within the season of application is minimal, if any.
