ABSTRACT:
A subterranean cavern having gas impermeable walls is used to store grain. The cavern has a controlled atmosphere without oxygen and preferably has an atmosphere of nitrogen. Access is provided to the cavern from the surface for the loading and outloading of the grain stored in the cavern. The grain is loaded into the cavern by conveying the grain to the access and then either allowing the grain to fall through the access into the cavern or by pneumatically conveying the grain into the cavern. The grain is outloaded from the cavern by a pneumatic conveyance system.
