Composting or Mulching of Grape Vine Winter Pruning Residues

Instead of burning the remains from the winter pruning of the vines, the remains are composted. One practice is in-situ mulching by spreading the pruning biomass in the corridors inside the vineyard and then passing over with a tractor and appropriate shredder implement so that the canes are broken into small pieces and are integrated with the soil. More optimally, grapevine pruning biomass can be chopped in a shredder and composted alone or in combination with other agricultural residues and the resulting compost can then be reused as organic fertilizer.
