Abstract

ABSTRACT The effects of soil texture on trace metal concentrations and geochemical fractions in an apple orchard soils were investigated. For this purpose, soil samples were taken from the apple orchards with two different soil textures located on the same geomorphological unit in Çanakkale, Turkey. A wet digestion was used to determine total trace metal concentrations, and a sequential extraction method was used to determine geochemical fractions of the metals. According to average total concentrations of all metals, except Pb, were found to be significantly higher (p < 0.05) in clay soils. Sequential extraction analysis showed that potential mobile fractions were ordered as Cd (68.8%) > Pb (52.4%) > Cu (42.0%) > Zn (34.8%) > Ni (32.3%) > Cr (22.9%) in clay soils and as Cd (61.6%) > Pb (51.6%) > Cu (40.2%) > Zn (30.7%) > Ni (30.8%) > Cr (24.9%) in loamy soils. The results revealed that all metals, except Pb, in exchangeable/acid soluble, oxidizable and, potential mobile fractions were found to be significantly higher in clay soils (p < 0.05). It was figured out that clay contents played an effective role in total concentrations of metals and their distribution in geochemical fractions.

土壤质地对苹果园土壤微量金属浓度和地球化学组分的影响(Çanakkale，土耳其西北部)

摘要研究了土壤质地对苹果园土壤中微量金属含量和地球化学组分的影响。为此，从土耳其恰纳卡莱同一地貌单元的两个不同土壤质地的苹果园中采集了土壤样本。采用湿法消解法测定总微量金属浓度，采用顺序萃取法测定金属的地球化学组分。根据除Pb外的所有金属的平均总浓度，发现粘土中的铅含量显著较高（p<0.05）。顺序提取分析表明，粘土中潜在的可移动组分依次为Cd（68.8%）>Pb（52.4%）>Cu（42.0%）>Zn（34.8%）>Ni（32.3%）>Cr（22.9%），壤土中潜在的移动组分顺序为Cd（61.6%）>Pb。结果表明，除Pb外，粘土中交换性/酸溶性、可氧化性和潜在可移动组分中的所有金属含量均显著较高（p<0.05）。

期刊介绍： rchives of Agronomy and Soil Science is a well-established journal that has been in publication for over fifty years. The Journal publishes papers over the entire range of agronomy and soil science. Manuscripts involved in developing and testing hypotheses to understand casual relationships in the following areas: plant nutrition fertilizers manure soil tillage soil biotechnology and ecophysiology amelioration irrigation and drainage plant production on arable and grass land agroclimatology landscape formation and environmental management in rural regions management of natural and created wetland ecosystems bio-geochemical processes soil-plant-microbe interactions and rhizosphere processes soil morphology, classification, monitoring, heterogeneity and scales reuse of waste waters and biosolids of agri-industrial origin in soil are especially encouraged. As well as original contributions, the Journal also publishes current reviews.
