Plants take up Sulphur from soil as a sulfate ion via the soil pore water. Fertilizers based on elemental Sulphur or thiosulfates must first be oxidized to sulfate for plant uptake and this process relies on microbial activity in soil. Sultech’s micron-sized sulphur particle size, translates into superior particle dispersion and spacing resulting in faster microbial conversion and plant uptake. For the crop producer, this means a faster return on the investment in high-analysis Plant Nutrient Sulphur (PNS).
Sultech’s safe and energy efficient process micronizes molten Sulphur through a pressure-controlled injection into a proprietary water/dispersant blend resulting in spherical micronized particles with a median particle diameter of less than 20 microns. (The diameter of a human hair is 50 microns, while a single grain of pollen is 7-10 microns in diameter).
Our sprayable product is distributed as a wet paste and will be available at a 0-0-0-70 Sulphur analysis. Our granular product will be available at a 0-0-0-90 Sulphur analysis.
Sulphur is one of the essential elements for crop production and soil quality. Plants use Sulphur to produce enzymes and proteins and stabilize nitrogen, contributing to the overall health of the plant. This leads to better plant growth, crop quality, yields and disease resistance.
PNS fertilizers are most commonly available in either the soluble sulfate form or an elemental Sulphur particulate product. Sulfate fertilizers are immediately available to crops but are prone to leaching below the root zone. Ammonium sulfate, the most widely used, is a low analysis Sulphur option with a high salt index. Conventional elemental Sulphur fertilizers are typically sold as pastilles of elemental Sulphur particles blended with bentonite clay. In the absence of adequate breakdown and dispersion of the pastille, a “localization effect” may occur. The particles can "stack" on top of one another, resulting in reduced contact with the soil, reduced effective surface area, and slower microbial oxidation to sulphate.
With these kinds of challenges, Sultech is offering a new option for Sulphur fertilizer application that will provide clear benefits to crop producers.
