Sulfur Bentonite is a type of sulfur fertilizer that combines elemental sulfur with bentonite, a clay mineral, to form granules. This formulation improves the handling, storage, and dispersion of elemental sulfur, making it more convenient for application. The bentonite serves as a carrier or matrix for the sulfur, as such sulfur is released gradually as it undergoes oxidation in the soil. The controlled release makes sulfur available to plants over an extended period of time. Bentonite clay, in addition to acting as a carrier for sulfur, can have soil conditioning properties. It may contribute to improving soil structure, water retention, and cation exchange capacity.
Sulfur bentonite, with its clay content, can be beneficial in sandy soils. The clay component in sulfur bentonite may help improve soil structure and water retention in sandy soils.
Sulfur bentonite may provide additional benefits in soils with low organic matter. The organic matter in the bentonite can contribute to soil improvement over time.
Controlled release of sulfur can be advantageous for crops that benefit from a longer nutrient release period.
*Both Sulphur Granular and Sulphur Bentonite can benefit a wide range of crops. The choice between sulfur bentonite and sulfur granular should consider the specific soil characteristics, target crops, and the desired release characteristics of sulfur.
