总结
从58耕地表土在苏格兰东南部的样品进行了分析，可湿性，可塑性，有机质含量，颗粒密度和粒度分布。采用工程土的方法对样品进行分类，并将所得分组与质地类别进行比较。工程土的分类标准提供了有关农田土壤可能的力学行为的有用信息。对15种土壤性质之间的相关性进行了试验。研究样品中的有机物含量从2%到10%不等，结果表明，有机物含量会影响若干机械性能，包括最佳含水量、最大干体积密度、液限和塑限。
最大容重和最佳含水量与Atterberg极限和有机质含量密切相关。液限比塑限与粒度分布的相关性更密切。与工程中遇到的土壤不同，这些土壤的颗粒密度与粒径分布无关，但与Atterberg极限一样，与有机质含量密切相关。
Summary
Samples from fifty-eight arable topsoils in south-eastern Scotland were analyzed for compactability, plasticity, organic matter content, particle density, and particle-size distribution. The samples were classified by the methods employed for engineering soils and the groupings so obtained were compared with the textural classes. The criteria for the classification of engineering soils provide useful information on the likely mechanical behaviour of arable soils in the field. Tests were made for correlation between fifteen soil properties. The organic matter content, which in the samples studied ranged from 2 to 10 per cent, was shown to influence several mechanical properties, including optimum moisture content, maximum dry bulk density, liquid limit, and plastic limit.
Maximum bulk density and optimum moisture content were strongly correlated with Atterberg limits and organic matter content. The liquid limit was more closely correlated with particle-size distribution than was the plastic limit. Unlike soils encountered in engineering, the particle density of these soils was not correlated with particle-size distribution but, like the Atterberg limits, was strongly correlated with organic matter content.
