Bale silage involves the preservation of perennial or annual forage crops. Either round or mid-sized square baling systems can be used to produce bale silage.
The key is that the baler needs to produce a dense bale. Soft-core bales are not as effective for making bale silage. Because the forage crop is baled, the silage is maintained as a long fibre forage source.
