viable cell concentration and luminescence activity of p. stutzeri p16 luxab4 was measured byplate counting and luminometery in sterile and non-sterile soil adjusted to matric potential of -1500, -750 and-30 kpa. results showed that matric potential had a significant effect on survival and activity of p. stutzerip16 luxab4 in soil. p. stutzeri p16 luxab4 could survive better in hutner’s minimal...

although the application of biodegradative genetically engineered micro organisms (gems) for bioremediation is very promising, the risks of their release should be assessed before their introduction into the environment. lux-marked ralstonia eutropha h850lr (formerly alcaligenes eutrophus h850lr) was introduced into sterile and non-sterile soil microcosms at matric potentials ?2.11, ?30, ?750, ...

Nature-based solution using vegetation has been considered as a sustainable and environmentally friendly approach to improve slope performance through root reinforcement variations of soil matric suction upon transpiration. During plant growth, roots explore pore space. How fundamentally the structure might evolve with time following growth dynamics how this dynamic soil-root interaction may mo...

Slope failure is a common phenomenon all over the world on both man-made and natural slopes. Prolonged rainfall one of climatic factors which largely responsible for slope failure. During heavy prolonged rainfall, part rainwater infiltrates through soil seeps into slope. The infiltrated water lowers matric suction increases porewater pressure. Eventually, generated pressure decreases strength r...

To build a comprehensive understanding of long-term hydro-mechanical processes that lead to shallow landslide hazards, this study explicitly monitored the volumetric water content (VWC) and rainfall amount for weathered granite soil slope over four year period. From 12 operational monitoring stations installed across South Korea, Songnisan station was selected as site. VWC sensors were placed i...

ABSTRACT An air pressure cell, a laboratory tool that precisely controls soil matric potential, was utilized in a novel approach to investigate the epidemiology and management of soilborne disease. Matric potentials of -1, -5, -20, and -40 kPa were established in cores of field soil infested with Wheat soilborne mosaic virus (WSBMV) and its presumed vector Polymyxa graminis. Equilibrated soil c...
