How Big Is A Micron?
Smart Nutrition MAP+MST analysis is 9-43-0 with 16% sulfur and the sulfur is mostly (around 90%) elemental sulfur. We know elemental sulfur needs to be oxidized into a sulfate form to become available to the crop. This requires warm soils and soil microorganisms to be active. The size of the sulfur particles can also help speed up the process. The smaller the size, the more surface area, and therefore oxidation can be sped up. So, how big is a micron? The sulfur size in Smart Nutrition MAP+MST is an average of 15 microns.
