As known, marine dredged materials (DMs) are highly nuisance wastes if they are not correctly reused or removed. In this work, the usability of DMs to the technical terms as manufactured topsoil (MT) in the urban landscaping works is discussed. Firstly, the leaching potentials of DMs were determined according to the related legislations to identify their hazardousness features. Secondly, DMs were subject to some treatment stages such as sieving, desalination, organic amelioration via peat and sheep manure, and pH adjustment to turn into an alternative natural soil pursuant to the British Standard in the scope of soil quality improvement studies as there is not any national standard in Turkey for the production of topsoil from different materials. Then, MT mixtures were prepared with washed and unwashed DM, peat and sheep manure in different mixing ratios (v/v); 33%, 50% and 67% DM, respectively. Consequently, high quality grass seed mixtures used for the landscaping applications were monitored for six months. The results demonstrate the availability of DM as alternative MT in the urban landscaping areas. Thus, important data were obtained as to the use of DM at alternative areas such as green city, green roof, shopping centers, organized industry, etc.
众所周知，如果海洋疏浚物料（DMs）没有得到正确的再利用或处理，它们就是极具公害性的废物。在这项工作中，讨论了DMs作为城市景观工程中人造表土（MT）技术术语的可用性。首先，根据相关法规确定DMs的浸出潜力，以识别其有害特性。其次，在土壤质量改善研究范围内，由于土耳其没有从不同材料生产表土的国家标准，DMs要经过一些处理阶段，如筛分、脱盐、通过泥炭和羊粪进行有机改良以及pH调节，以变成符合英国标准的替代天然土壤。然后，用洗涤过和未洗涤过的DM、泥炭和羊粪以不同的混合比例（v/v）制备MT混合物，分别为33%、50%和67%的DM。最后，对用于景观应用的高质量草籽混合物进行了六个月的监测。结果表明，DM可作为城市景观区域的替代MT。因此，获得了关于在绿色城市、绿色屋顶、购物中心、工业园区等替代区域使用DM的重要数据。
