Terms & Definitions
Soil texture is a measure of the percent of sand, silt, and clay in the soil. It is combined with grade and structure to determine the water loading rate.
Extra test required to determine whether Sand, Loamy Sand, or Sandy Loam should be classified as Very Fine, Fine, Medium, Coarse, or Very Coarse.
Prismatic soil is similar to columnar but younger and does not have rounded tops. It can cause potential failures in a septic system. In order to build with prismatic soils, the Standard of Practice from 2015 in Alberta requires four additional tests: SAR, COLE, Dispersion and EC.
