Plant–soil feedback responses of four dryland crop species under greenhouse conditions

open access: yesPlant-Environment Interactions, 2020
Why this research Matters Plant–soil feedbacks (PSFs) give a mechanistic understanding on how soil properties established by previous plant species go on to influence the performance of the same or different species in monoculture, intercropping or crop ...

Study of the Permeability of Foam Conditioned Soils with Laboratory Tests [PDF]

open access: yes, 2010
EPB tunneling requires that the excavated soil has a plastic and pulpy behavior to be able to apply a stabilizing pressure to the face, but it should also be impervious to counteract filtration forces that could develop ahead of the face.
