Physical Properties of Granular Fertilizers and Impact on Spreading
Commonly, particle size is reported as the median particle size (d 50) or Size Guide Number (SGN) of a sample. Particle size distribution can be expressed using GSI (Granulometric Spread Index) or UI (Uniformity Index) with companies possibly reporting one or both on fertilizer specification sheets.

SGN (Size Guide Number) The size guide number of a material is a commonly used specification to describe particle size characteristics. SGN is the mean, or average, of the particle sizes that make up the product.
SGN (Size Grade Number) is the measurement of granule size in millimeters multiplied by 100. A product’s SGN will afect spread width. Materials with poor uniformity (a significant percentage in 3 or more colums of scale device) may be dificult to spread accurately.
