The present study investigates the effect of three different methods of obtaining 1:1 and 1:5 soil-over-water mass ratios (soil:water) extracts for soil electrical conductivity (EC) measurements (EC1:1, EC1:5). On the same soil samples, also the electrical conductivity of the saturated paste extract (ECe) was determined and the relationships between ECe and each of the three of EC1:1 and EC1:5 values were examined. The soil samples used were collected from three areas over Greece (Laconia, Argolida and Kos) and had ECe values ranging from 0.611 to 25.9 dS m−1. From the results, it was shown that for soils with ECe 3 dS m−1. Also, in the case of EC1:5, the optimal times for equilibration were much longer when ECe 3 dS m−1), while one method (23 h rest and then shaken mechanically for 1 hour) showed significant differences in the slopes of the linear relationships between the two ranges of ECe.

基于 1:1 和 1:5 土水比的方法的土壤 EC 值与基于饱和糊提取物的方法的 ECe 的比较

本研究调查了获得 1:1 和 1:5 土壤-水质量比（土壤:水）提取物的三种不同方法对土壤电导率 (EC) 测量（EC1:1、EC1:5）的影响。在相同的土壤样品上，还测定了饱和糊状提取物 (ECe) 的电导率，并检查了 ECe 与三个 EC1:1 和 EC1:5 值之间的关系。所使用的土壤样品采集自希腊的三个地区（拉科尼亚、阿尔戈利达和科斯），ECe 值范围为 0.611 至 25.9 dS m-1。结果表明，对于具有 ECe 3 dS m-1 的土壤。此外，在 EC1:5 的情况下，当 ECe 3 dS m−1) 时，平衡的最佳时间要长得多，
