Frequently Asked Questions

First of all the bale wrapping process is determined by a good baling process. Make sure to wrap the bale quickly after the baling process. You should use plastic twines or nets and make a high cutting (that is <10 cm) to prevent any soil contamination which could contain mushroom spores.

Wrap the bale with at least 6 layers to all sides when the silage quality is standard and apply at least 8 layers of film when the silage quality is ligneous (such as alfalfa) to achieve a satisfactory result. The layers of the film shall overlap 50% to one another around the silage bale. For continuous bale wrapping apply at least 6 layers of film (8 layers are recommended) around the bale and make sure to wrap bales of the same size to ensure a good tightness of the continuous bale.

The film on the bale shall be stretched by 50% in the length direction when measured on the flat end of the bale. Check it frequently during the process. The width of the stretched film shall be of 400 mm with a nominal width of 500 mm and of 600 mm with a nominal width of 750 mm.

We suggest wrapping your bales when there is no rain as this can damage the wrapping process.

Bales should be between 40 % and 60 % of dry matter to obtain food quality silage.

The stacking of the bales should be made on the flat end of the bale. They can be stacked three high maximum.

It is recommended to store the bales near the farm. The storage area shall ideally be flat, preferably cemented. The storage area shall be away from trees and far from any water source, ditch or field drainage. It is also recommended to protect the bales from animals.
