“…Compost has been recognized and widely used as a conventional method for winery wastes treatment (Bertran et al, 2004). There are also some other methods for recovering several valuable materials from the wastes, such as tartrate recovery from grape skin and lees, and natural colours extraction from grape skin.…”

Biocontrol agents are safe and environmental friendly alternatives for pesticides in agriculture application. Trichoderma viride WEBL0703 performed a high level of antagonistic activity toward a broad spectrum of phytopathogens and was determined as a biocontrol agent, which was produced by solid state fermentation using grape marc and wine lees. The maximum yield of T. viride conidia was up to 6.65 × 10 9 CFU/g initial dry substrate (IDS) after 10 d fermentation. As important enzymes for protecting plants from disease, chitinase, β-glucanase, and pectinase yields were 47.8 U/g IDS, 8.32 U/g IDS and 9.83 U/g IDS, respectively. These results show that it is feasible to convert winery wastes to a value-added and environmental friendly biocontrol agent.

“…Grape pomace has so far been investigated as a fertilizer or soil conditioner [10][11][12][13] , as biomass for biofuel production [14][15][16] and as animal feed [17][18][19][20] . Wet grape pomace is a highly perishable material subject to uncontrolled microbial spoilage owing to its high moisture content (~60 % wb ) and water activity.…”

“…At the experiment time all the materials were stabilized, since the C-to-N ratio was equal or lower than 10. The material can be considered, in this case, as mature compost, with all the benefits that this would bring to crop production (Bertran et al, 2004).…”

In the present work, different strategies for the utilization of an organic beekeeping waste called «slumgum» were analysed. Slumgum appears in the beeswax-rendering process. A physico-chemical characterization was carried out and the hypothesis that slumgum could be used as nutrient source and growth substrate constituent for seedling production was tested. Analyses revealed that slumgum has an important potential for fertilization: 6.10% N, 0.23% P and 0.4% K, with a total organic matter average content of 78.63%. Also, some disadvantages such as an overly acid pH and high electrical conductivity were found. Assays of seedling production were carried out for two years and lettuce and pepper were used as model crops. Treatments were performed mixing different slumgum formats [minced slumgum (MS), slumgumgypsum granules (SG) and slumgum-superphosphate granules (SC)] with peat (Pe): 25MS-75Pe (in %), 33MS-67Pe, 25SG-75Pe, 33SG-67Pe, 25SC-75Pe and 33SC-67Pe. Controls were no fertilized peat, organic and mineral commercial fertilizers. The best results for lettuce and pepper leaf area, shoot dry weight, and N percentage in leaf were obtained when treatment 25MS-75Pe was applied. Moreover for treatments 25SG-75Pe, no significant differences were observed with respect to the controls in seedbed parameters. Important reductions in emergence and seedling production were detected with SC, most probably due to their high acidity. Results suggest that MS (25MS-75Pe and 33MS-67Pe) and 25SG-75Pe offer a relevant nutritional potential and their high organic matter contents allow them to be considered as organic fertilizers.Additional key words: compost, fertilizer, granulation, organic matter, organic residues, slumgum. Resumen Caracterización de residuos de industrias apícolas para su utilización en la producción de plantelesEn este trabajo se analizaron diferentes estrategias para la utilización de un residuo orgánico de la industria apíco-la llamado «carozo», que se obtiene del proceso de extracción de cera. Se realizó una caracterización físico-química del residuo y se contrastó la hipótesis de que podría utilizarse como fuente de nutrientes y constituyente de sustratos para la producción de planteles hortícolas. Los análisis revelaron un importante potencial como fertilizante: 6,10% nitrógeno, 0,23% fósforo y 0,42% potasio, con contenido medio en materia orgánica del 78,63%. No obstante, presentó como inconvenientes un pH ácido y elevada conductividad eléctrica. Se realizaron, durante dos años, ensayos de producción de plantel eligiendo lechuga y pimiento como modelos. Los tratamientos fueron formulados mezclando distintos formatos de carozo [carozo picado (MS), gránulos yeso-carozo (SG) y gránulos superfosfato-carozo (SC)] con turba (Pe): 25MS-75Pe (en %), 33MS-67Pe, 25SG-75Pe, 33SG-67Pe, 25SC-75Pe y 33SC-67Pe. Los controles fueron turba sin fertilizar y dos fertilizantes, orgánico y mineral, comerciales. Los mejores resultados en ambos cultivos para área foliar, peso seco de parte aérea y porcentaje de nitróge...
