Basically, the activity of the methane oxidizing bacteria is limited by the availability of oxygen in the landfill cover soil. Enforced by the use of fine-grained soils like silt, the surface tends to crust due to vertical erosion, blocking pores required for gas exchange. A column study was carried out to examine the impact of vegetation on improving the aeration of critical soil material and ...

holocene in southwest khuzestan is represented by a fluvio-tidal succession termed thebahmanshir series which consists of two clayey layers separated by silty sand to silt beds. this paperdescribes the geotechnical properties of the clayey layers that have wide exposure in the lowlands of thepersian gulf coast. studied layers are generally clay sized and consist of a lesser percentage of clay m...

Soil contamination by different hydrocarbons has rapidly expanded worldwide, surpassing the self-purification capacity of soils and increasing number contaminated sites. Although much effort been devoted to study effects diesel on geotechnical properties soil, there is still limited available information about it. Moreover, no maximum retention that soil can have its effect behavior soil. Thus,...

Consolidated-drained triaxial compression tests were conducted to compare the stress-strain and volume change response of sands and clayey sands reinforced with discrete randomly distributed poly-propylene fibers. The influence of various test parameters such as fiber content (0.0%, 0.5% and 1.0% by weight), clay content (0%, 10% and 20% by weight), relative density (50% and 90%) and confining ...

This study explores whether Thermomagnesium (TM), a by-product of Ni ore mining, is an efficient fertilizer for maize. The effects TM on soil pH, the supply Si and Mg to plants, carbohydrate metabolism, grain filling, yield were assessed in two simultaneous experiments performed greenhouse conditions. Five doses applied textures—clayey (0, 55, 273, 709, 2018 mg kg−1) sandy 293, 410, 645, 1260 k...

In central Mexico, agricultural irrigation reusing Mexico City's municipal wastewater has been occurring for the last century, resulting in the recharge of the local aquifer. However, groundwater of this zone is of good quality, indicating that the microorganisms contained in wastewater are retained by soil after infiltration. This study aims to assess the capacity of three agricultural soils t...
