• Sulfur Granules 

Sulfur granules are aggregates of microorganisms admixed with inflammatory debris characteristically but not exclusively found in actinomycosis. Granules vary in colour (white to yellow) and size (0.25 to 2 mm in diameter). Sulfur granules may be absent or poorly organized in an occasional case of actinomycosis.

Pure elemental sulfur is a vital secondary macronutrient that can be applied to deficient soils or in places where it is necessary to lower pH for acid loving plants.
