Effects of soil water content and soil sodicity on soil shearing strength 土壤含水率与土壤碱度对土壤抗剪强度的影响
2.
Some soils are affected by salinity - alkalinity : about 15 % of irrigated area suffer from varying degrees of salinity and sodicity and about 10 % from water logging 一些土壤受盐碱影响：约15 %的灌溉面积有不同程度的盐化和苏打碱化，约10 %的土壤受淹水之苦。
