Description: Farmers in western Canada are using much more commercial fertilizer than they did 20 yr ago. Consequently, storage of fertilizer in bulk is now common both in small towns and on farms. Knowledge of the frictional properties of fertilizers is needed if bulk storages are to be designed by engineering methods. Common formulae for estimating pressures in granular materials depend on the internal friction angle, the co-efficient of friction of the granular medium on the bin walls and the ratio of lateral to vertical pressure. This ratio is usually calculated from the internal friction angle, and sometimes from both the internal and wall friction angles. Information on these is therefore essential to pressure calculations.
Keywords: friction properties of fertilizers
