Impacts of drying–wetting cycles on rhizosphere respiration and soil organic matter decomposition [PDF]
, 2013 Drying-wetting cycles influence both soil organic matter (SOM) decomposition and rhizosphere processes. Rhizosphere processes also affect SOM decomposition through rhizosphere priming. However, little is known about how drying-wetting cycles regulate SOM

Influence of Dry-Wet Cycles on the Structure and Shear Strength of Loess
Sustainability, 2023 The dry-wet cycle is an important factor that causes slope instability and foundation settlement in loess regions. In order to study the effects of the dry-wet cycle on the structure and shear strength of loess, isotropic compression tests and triaxial shear tests were carried out on loess with different numbers of dry-wet cycles. The results show that
