Of all the process of silo production, this is the stage where full attention should be paid as it is fundamental in the final quality of the reserve.

The material should be intensely compacted in very thin layers, to avoid having great masses where it becomes very difficult to extract the air adequately.

The key is to eliminate all the oxygen that fostersthe development of yeasts.

In order to have good compaction, it is necessary to use very powerful and heavy tractors, with simple wheels or weighted down dual wheels with bulldozer shovels and tail compacting rolls.

No earth should be taken to the silo on the tractor wheels.

It is necessary to coordinate the capacity of chopping with that of compaction so as not to have great volumes of material that can hardly be well compacted.
