Description: Bottom-unloading oxygen-limited farm silos appear to occupy an increasing share of the overall farm silo construction volume. This type of silo allows a more automated feed-handling system than do most top-unloading silos. As well, the first-in first-out feature allows for a more or less continuous feed storage system. At present, bottom-unloading silos are used mainly for the storage of high-moisture corn or of legumes, or legume grass mixtures. With the latter the unloading equipment causes a cavity to form in the bottom of the silo as the rotating unloading auger moves material to the centrally located unloading hopper. The large cohesive strength of the whole-plant material allows a dome-like cavity to form which collapses at discrete intervals when arch support becomes inadequate.
