| The importance of the winery industry in Mediterranean regions is accompanied by the generation of big amounts of wastes from the wineries and distilleries. The agricultural use of exhausted grape marc after composting is evaluated in this study under field conditions, considering both yield and environmental aspects. A field experiment was carried out in Ciudad Real (central Spain) where melon crop was grown under drip irrigation. This area was designated ?vulnerable zone? by the Nitrates Directive 91/676/CEE. Melon crop has been traditionally cultivated in this area under drip irrigation with high inputs of water and fertilizers, but no antecedents of application of winery and distillery wastes are known. In a randomized complete block design, four treatments were established: three compost doses consisted of 7, 13 and 20 t compost ha-1 and a control without compost addition. Drainage and nitrate concentration in the soil solution were measured weekly in the plots to determine N leached during the crop period. Crop yield was also followed by harvesting plots when a significant number of fruits were fully matured. The addition of exhausted grape marc compost showed an increase in crop yield with a low environmental risk. | |
