The number of round bales possible from any roll of netwrap is dependent on at least three things:
and – most importantly
The following table shows the approximate net use on varying sized bales in different crops.
Many modern balers are equipped with a crop pre-cutting device which, when used in silage, can produce bales containing up to 20% more forage than a ’standard’ bale. This significantly increases the bale weight and density, and requires a corresponding increase in the amount of net that is used to hold the bale securely. Consequently, it is recommended that at least an extra 0.5 turns of net is applied to chopped silage bales. Likewise, when baling high density straw, it may also be necessary to increase the number of turns by at least 0.5 per bale to ensure it remains securely wrapped.
