TL;DR: In this article, a number of transport pathways, processes, factors, and mathematical models often are needed to describe pathogen fate in agricultural settings, and the level of complexity is dramatically enhanced by soil heterogeneity, as well as by temporal variability in temperature, water inputs, and pathogen sources.

TL;DR: In this article, the functional significance of microbial activity in the host porous medium in terms of feedback mechanisms instigated by irregular water availability and related physical and chemical conditions that force the organization and formation of unique microbial habitats in unsaturated soils that prompt and potentially perpetuate the formation of preferential flow paths in the vadose zone.

TL;DR: In this paper, the authors measured breakthroughs of biochar pulse under three pH and two ionic strength (IS) levels, and fitted BTCs to a convection-dispersion model with kinetic and equilibrium deposition sites to estimate the key transport parameters (e.g., biochar deposition rate coefficients).

TL;DR: Investigation in unsaturated columns by increasing concentrations of colloid influents with varying ionic strength found that the wedge-shaped air-water-solid interface could form a "hydrodynamic trap" by retaining colloids in its low velocity vortices, which could explain the greater retention with increased input concentrations.

TL;DR: In this paper, the authors explore the deposition mechanisms of graphene oxide (GO) particles in porous media with various combinations of moisture content and ionic strength, and find that retention and transport of GO in porous materials are strongly dependent on solution ionic strengths.
