Production and use of granular fertilizers has increased dramatically during the past decade. Sales in Western Canada have increased from about 55,000 tons annually in 1955 to more than 800,000 tons in 1967 (1). This total production was from six plants (there are presently seven). Only two plants manufactured fertilizer in 1955.Two problem areas have resulted from the increase in fertilizer sales. Firstly, the fertilizer industry has found difficulty in handling and distributing the great quantities of fertilizer, especially when a large portion of this volume is required during the spring of the year. Secondly, some obvious limitations to bagged fertilizer have become evident with increased application rate. Handling fertilizer in bulk would in crease the efficiency on many farms. If this bulk product were taken from the manufacturing plant during the off season, their storage and distribution difficulties in the spring would be reduced. The problem then is to design economical farm storage bins or buildings that can keep bulk fertilizer in good condition for several months. Inquiries regarding the storage of bulk fertilizer could not be answered satisfactorily by either knowledge or experience. A brief literature review failed to yield any desired information. Brittona reported a similar lack of information on bin pressures and storage characteristics of fertilizer.
