TRENCH SILO

• The process of ensiling using trench silo is more or less similar to pit silo but the only difference is size because trench silo usually have greater length in relation to breadth.

Advantages of trench silo: Tractors can be used to pack silage. Less power is required for filling the trench silo. Well adopted to ensile immature corn etc., There is minimum chance of air getting into the silo as major part of material conserved will settle into the trench below ground level. Unloading and carrying of silage are much easier. Disadvantages of trench silo: Once constructed, it is not easy to abandon. Relatively more silage is spoilt. The trench silo must be trimmed upon the edges & cleaned.
