Contrasting pathways of carbon sequestration in paddy and upland soils
Global Change Biology, 2021 Paddy soils make up the largest anthropogenic wetlands on earth, and are characterized by a prominent potential for organic carbon (C) sequestration. By quantifying the plant‐ and microbial‐derived C in soils across four climate zones, we identified that

Assessment of Soil Tunnel Interaction in Sand Soil
IOP Conference Series: Materials Science and Engineering, 2019 Abstract In this study, series of shaking table tests were carried out to investigate the effect of tunnel model depth and direction of ground acceleration on the ground surface settlement and the dynamic earth pressure on the tunnel wall. Box tunnel model is embedded in dry and saturated soil (Karbala Sand).

Shaking table test on underwater slope failure induced by liquefaction
Soils and Foundations, 2023 Sand liquefaction is a process in which the excess pore water pressure of saturated sand soils increases and the effective stress of saturated sand decreases under the action of vibration, resulting in the transition of sand soils from the solid state to

Shear strength behavior and parameters of microbial gellan gum-treated soils: from sand to clay
, 2019 Microbial biopolymers have recently been introduced as a new material for soil treatment and improvement. Biopolymers provide significant strengthening to soil, even in small quantities (i.e., at 1/10th or less of the required amount of conventional ...

Trace Element Content in Soils with Nitrogen Fertilisation and Humic Acids Addition
Agriculture, 2023 Application of mineral fertilisers can entail an increase in trace element content in the soil. In consequence, their elevated uptake by plants and transfer to further trophic chain links may occur.

Experimental Investigation of Unsaturated Silt‐Sand Soil Permeability [PDF]
Advances in Civil Engineering, 2018 The permeability of unsaturated silt‐sand soil is important in many geotechnical and geoenvironmental challenges. Therefore, an appropriate method to evaluate silt‐sand soil permeability is important, particularly in Iran where it received little consideration.
