The stress path is a critical factor affecting the mechanical properties of saline soils. In order to study soils under different paths, in situ Qian’an area western Jilin province were selected for this study, and triaxial shear tests six paths conducted, including consolidated undrained test conventional isobaric consolidation condition; drained conventional, equal p, reduced increased p K0 c...
Similar to plants, soil salinity may reduce microbial growth and activities in different ways. The aim of this study was to determine the effects of different levels of salinity on some microbial indices in the presence and absence of plant's living roots. In this study, five levels of salinity using NaCl, CaCl2, MgCl2 and KCl and three soil media (soil with no plant, soil cultivated with wheat...
Capacitance and resistivity sensors can be used to continuously monitor soil volumetric water content (θ) and pore-water electrical conductivity (EC(p)) with non-destructive methods. However, dielectric readings of capacitance sensors operating at low frequencies are normally biased by high soil electrical conductivity. A procedure to calibrate capacitance-resistance probes in saline conditions...
