SOP Granular

SOP Granular is like most potash fertilizers in that it can be processed into a variety of different particle sizes and forms to meet various market needs. It is typically available in the form of powder, compaction granules, or round pellets or granules. While powdered potassium sulfate provides fast nutrient delivery, SOP granular can be difficult to handle and transport and often becomes windblown upon application.
