Abstract

In this study was conducted to investigate mineralization potentials of different land uses in the area of Genya Mountain-Artvin in 2011. For these purposes, soil samples were taken from surface 0-15 cm depth in young spruce stands, old spruce stands and spruce stand with Rhododendron understory, and adjacent grassland sites with similar parent material, slope and aspect. Samples were subjected to standard incubation technique in laboratory conditions (60% MSK and 25°C). Mineralization rate differed significantly among sites. Nitrification rates were significantly higher in grassland sites compared to other sites (174.61 N ha 21 day-1). There was a strong positive correlation between nitrate production rate and soil organic matter content (r2=0.70) and total N contents of soils (r2=0.80). There was also a negative correlation between nitrification rate and C/N content (r2=-0.48). Although soil organic matter contents of soils were relatively high, N mineralization rate wasn’t as high as expected. It was argued that the reason behind these lower rates was relatively high acidity in soils of the sites.

地下不同植物地层的矿产潜力（Artvin Genya Mountain Walk Turkey）

本文对2011年根亚山-阿尔文地区不同土地利用方式的矿化潜力进行了研究。为此，土壤样品取自幼龄云杉林、老云杉林、杜鹃花林下层云杉林以及具有相似母质、坡度和坡向的邻近草地，深度为0 ~ 15 cm。样品在实验室条件下(60% MSK和25°C)进行标准孵育技术。矿化率在不同地点差异显著。草地样地硝化速率显著高于其他样地(174.61 N ha 21 d -1)。硝态氮产量与土壤有机质含量(r2=0.70)和全氮含量(r2=0.80)呈极显著正相关。硝化速率与C/N含量呈负相关(r2=-0.48)。土壤有机质含量较高，但氮矿化率未达到预期值。有人认为，这些低速率背后的原因是这些地点的土壤酸度相对较高。

期刊介绍： Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance. The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
