Excerpts from the report: Reductions in stock available for storage, a continued surplus of storage facilities, and increased cost of inputs caused a sharp increase in grain storage costs in 1967-68 and in estimated costs for 1969-70. Lower average occupancy, only 39 percent in 1967-68 and about 40 percent in 1969-70 compared with 62 percent in 1964-65, was the major reason for higher costs. This conclusion is based on an analysis of a subsample of 96 of the 252 firms studied in 1965 and reported in Costs of Storing and Handling Grain in Commercial Elevators, 1964-65, USDA, ERS-288, April 1966. The current study was designed to determine the changes that had occurred in volumes stored and handled, wage rates, total wages, assets, and other pertinent information affecting costs of handling and storing grain. Differences in volumes and costs at the plants studied for the 2 years were used as the basis for estimating changes occurring since the 1964-65 base period. Detailed information on the methodology used is given in the appendix.
