Correlation Between Soil Water Retention Capability and Soil Salt Content

摘要

The soil moisture retention capability of Chao soil and coastal saline Chao soil in Shandong and Zhejiang rnprovinces were measured by pressure membrane method. The main factors influencing soil moisture retention rncapability were studied by the methods of correlation and path analyses. The results indicated that ＜ 0.02mm rnphysical clay and soil salt content were the main factors influencing soil moisture retention capability. At soil rnsuction of 30～50 kPa, the soil salt content would be the dominant factor.
