The success of phytoremediation of soil contaminated with hydrocarbons is conceptualized to occur through four different mechanisms, namely phytostabilization, phytodegradation, phytovolatilization and rhizodegradation (Germida et al., 2002). 2.2.1 Phytostabilization In phytostabilization, the root zone acts...
Biological soil stabilizationShear strengthSoil micro-fabricBacillus sphaericusIn many engineering projects, improving soil shear strength is one of the goals. There are different methods for soil improvement among which biological soil stabilization techniques have emerged in......
Land degradation is a serious threat to agriculture which is adversely affecting the soil functions and productivity, while degraded soils stretch up to 6 billion ha worldwide. The population of the world is increasing day by day and agricultural land is
Growth and Nutrient Content of Herbaceous Seedlings Associated with Biological Soil Crusts Biological soil crusts of arid and semiarid lands contribute significantly to ecosystem stability by means of soil stabilization, nitrogen fixation, and im...

Besides, in terrestrial ecosystems, SOC controls a host of soil physical, chemical, and biological processes affecting plant growth and sustainability (Lal, 2004). In spite of research efforts, carbon stabilization mechanisms in soil and the factors affecting them is still not well understood. ...
(e.g. carbohydrates). Our inspiration for using biopolymers in geotechnical engineering is: 1. low environmental impact; 2 sustainability; 3. non-toxicity and 4. low cost, typical of biological stabilization methodologies35. A number of reviews have highlighted their significant potential in ...
biological activity by formation of biopores and soil aggregates55,56. To capture this primary effect and as a first-order approximation, we propose linking soil structure and associated hydraulic parameterization with vegetation via local Gross Primary Production (GPP) as a surrogate for biological ...
Soil microorganisms from terrestrial habitats are key determinants of ecosystem services, e.g., nutrient cycling [1], stabilization of soil organic matter, and sequestration of carbon [2,3]. Bacterial communities play an important role in soil, contributing to such processes as organic matter turn...
