Sulphur Prills
Long-lasting elemental sulphur with superior handling and application performance.
BioFert Sulphur Prills® contain 90% fine elemental sulphur particles blended with bentonite clay and formed into durable pastilles. This formulation delivers a dust-free, concentrated source of sulphur with excellent granule strength, making it ideal for aerial topdressing, ground spreading, and bulk blending with other fertilisers.
When exposed to moisture in the soil, the bentonite clay swells and fractures the pastille, releasing thousands of microscopic sulphur particles. This ensures an even distribution across the paddock and provides a steady conversion of elemental sulphur into plant-available sulphate over time. Unlike soluble sulphate fertilisers that are prone to leaching, BioFert Sulphur Prills® provide a slow-release, season-long supply of sulphur matched to crop demand.
Sulphur is an essential nutrient for protein production, photosynthesis, and efficient nitrogen use. Deficiencies can reduce crop growth, chlorophyll formation, and clover nodulation, ultimately lowering yields and pasture performance. With modern fertiliser programmes using more sulphur-free phosphate and nitrogen sources, sulphur supplementation has become critical in New Zealand farming systems.
