SGN Scales

Identify your fertilizer blend’s Size Guide Number with a Sylvite SGN Scale.

Why It’s Important

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.

Particle size is the most important factor in the selection of non-segregating materials. Particle size is commonly identified by SGN, the median dimension in millimeters times 100. For example, if the screen test indicated that a sieve of 2.40 mm opening would retain exactly one half of the sample, the average particle size would be 2.40 mm, or SGN 240.
