Özet

Composting is the process where organic wastes are decomposed by microorganisms under aerobic conditions. Through this process, soil-regulating compost is produced from organic wastes, which contains nutritional elements for plants. This study aims to produce compost from broccoli wastes. Wheat straw, animal manure and broccoli wastes were used in the composting process. The objective of the study is to determine the optimum mixture ratio of the organic wastes used for composting and present the nutritional level of composts. To that end, composting experiments were conducted in reactors and wastes were mixed at five different ratios and simultaneously subjected to the process. Indicative parameters obtained from the experiments were examined and it has been concluded that the mixture consisting of 30% cattle manure, 20% straw and 50% broccoli wastes provides the best composting process. Highest values in terms of nutritional content of composts were obtained from R5 reactor (70% manure, 20% straw and 10% broccoli wastes) except for N and K (30% cattle manure, 20% straw and 50% broccoli wastes). The best values of EC and pH were obtained from R5 reactor (70% manure, 20% straw and 10% broccoli wastes). The increase of proportional amount of the broccoli wastes in the mixture boosted the success of composting. The organic waste materials must be reused by composting for prevention of pollution.
