Abstract:
Rootstocks disposal in orchards and vineyard at the end of the productive-cycle is a costly and necessary operation traditionally performed using excavator or specific grinders. Nowadays, the problem of the rootstock disposal has become even more common respect some years ago, because orchard and vineyards are now grown as intensive cultivation requiring frequent turnover. In case rootstocks are extracted from the ground, these are successively loaded in trailers and disposed in specific landfills or composting facilities. The management of this residue includes costs such as removal, loading, transport and disposal that till now cannot be offset because the valorization of this material seems unreliable for its scarce quality. In this work, a commercial continuous single pass rootstock extractor was tested to assess its performance during removal operations in two vineyards trained using different systems. Biomass availability was evaluated on the base of the clean dry product obtained per hectare from each vineyard. Results show interesting biomass yield per hectare and interesting machine performance respect traditional methods. In general terms, the paper demonstrated the good potential of biomass obtainable from end-life vineyard, but also highlighted the need to improve the biomass quality for efficient bioenergy conversion.
