SGN Scales - Sylvite
The Sylvite SGN Scale is an instrument designed for simple screen tests of fertilizer samples. It is a small Plexiglas box fitted with five sieves. It directly produces a size histogram of the sample tested, from which the Size Guide Number (SGN) can be estimated.
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.
Physical Specifications for Granular Fertilizer and Soil …
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.
what is SGN??? - Lawn Care Forum
2008年5月25日 · SGN refers to the prill size of any given fertilizer. The higher the SGN rating, the larger the prills will be. For example, a fertilizer with an SGN rating of 200, will have bigger prills than a fertilizer with an SGN rating of 150.
Particle Distribution in Fertilizer: Why It’s Really Important
2021年4月20日 · SGN is the particle size measured in millimeters, multiplied by 100. For example, let’s compare applications with 100 SGN and 200 SGN products. Particles with 200 SGN will weigh more than twice that of the 100 SGN particles.

Size Guide Number (SGN) and Uniformity Index (UI) The Size Guide Number and Uniformity Index both accurately define the size of a fertilizer. SGN is the average millimeter (mm) diameter of that fertilizer. The Uniformity Index defines how …
• Select proper SGN • Use homogenous products • Consistently high UI (blended product) • Check distribution of spreader • Use proper spacing between passes
Particle Size Conversion Table | PDF - Scribd
This document provides a particle size conversion table that lists standard mesh sizes used for sieving, along with the corresponding nominal sieve opening sizes in inches, millimeters, and microns. It also explains that larger mesh sizes (>1/4 inch) refer to the sieve opening size in inches, while smaller mesh sizes (#3 1/2 to #400) refer to ...
