I have never done any bale silage. But I do have a 20x60 foot upright stave silo that I have used in the past, mainly put corn silage in it. They are somewhat of a pain when the unloader or something does not work properly in it. I found that as long as you pack the silage good an outside pit that can be loaded with a loader is pretty keen and very simple. Due to the drought we had this year alot of corn was chopped for silage. NOt to change the subject, but what is good cropland bringing in your area? WE just had a neighbor that died he had 270 ac of excellent farm ground that brought $10,000.00 / acre that was sold in 3- different tracks.
