RESULTS AND DISCUSSIONThe wine industry uses large amounts of chemical fertilizers and organicsubstances (Kammerer et al., 2005; Arvanitoyannis et al., 2006). Prevention ofpossible vineyard crop diseases is a good way to present composting as the mostsuitable process for the organic waste reuse in the wine industry in vinayard crops(Ruggieri et al., 2009).Tab. 1 Total bacterial number (CFU x10 6 ) in different types of wasteType of waste Autumn 2009 Spring 2010 Autumn 2010 AverageComminute pruning 3.2 5.8 4.23 4.41woodGrape marc 6.13 31.6 4.88 14.20Mixture 1:1 pruning 10 75.33 5.96 30.43wood and grape marcAverage 6.44 37.58 5.02 -The experiment results indicate different presence of the total number of bacteria,depending on the transformation process duration. Bacteria were the mostnumerous in Spring 2010, which indicates that the most intensive transformationprocesses took place during that time (Tab. 1). Bacteria were the least numerouswithin the comminute pruning wood type of waste, while they were the mostnumerous within the pruning wood and grape marc mixture.There were no considerable fluctuations in the number of Azotobacteras amongdifferent treatments in Autumn 2009 and 2010, while the fluctuations were obviousin Spring 2010 (Tab. 2). Azotobacteras were the least numerous within thecomminute pruning wood type, while they were the most numerous within the 1:1proportion of pruning wood and grape marc mixture. Bacteria were more numerouswithin the 1:1 proportion of pruning wood and grape marc mixture due to the largerquantity of available carbon and higher aeration. There was a gradual drop in pHvalue, which was mildly neutral. The carbonate content was low.There were no considerable fluctuations in the total nitrogen content amongdifferent treatments, while there was the highest presence of ammonium nitrogenand available phosporous within the 1:1 proportion of pruning wood and grapemarc mixture. The highest content of nitrate nitrogen and available potassium wasrecorded withinn the grape marc type.As for the C/N proportion values, there were no considerable differences amongthe treatments, but the most important ones were recorded within the comminutepruning wood type. When organic matter passes through successive cycles ofdecomposition, the C/N ratio becomes smaller (White, 2003). The previousstatement has been confirmed by our results: the C/N ratio of decomposers in well249
