Stack-Trench Silos
Stack-trench silos have been used by Washington farmers for many years. These silos have saved thousands of tons of valuable cattle feed. Now that more feed is needed, many farmers can increase their stored feed by using a silo. Materials for upright silos are scarce, so the stack-trench can be used to good advantage although spoilage in the stack-trench may be greater than in an upright silo.
