Beet vinasse (desugared, beet molasses) was co-composted with each of three following solid agricultural residues: grape marc, olive press cake and the cotton gin trash.

Compost had no detrimental effects on the growth parameters and nutritional status of corn. compost treatments produced yields (weight of grain) that were higher than those obtained for mineral fertilizers.
