Tests for Grades of Topsoil
BS3882 Top Soil Suite
The BS gives ranges of compliance for each test for the different grades of topsoil. The test report, or ‘declaration of compliance’ as BS3882 terms it, shows the compliance of a given test sample against the different grades of topsoil. Compliance is shown as Y (Yes, complies with) and N (No, does not comply with).
An overall Soil Texture is determined from the results of the fractions of Clay, Silt & Sand compared against the soil triangle matrix in BS3882.
The Multipurpose grade is self explanatory and the specific purpose grades are as follows:
Acidic = topsoil required for acidic growing conditions
Low Fertility = topsoil with lower nutrient concentrations
Calc = Calcerous soil
