Arbuscular mycorrhizal fungus inocula from coastal sand dunes arrest olive cutting growth under salinity stress
(2020)Cultivation of olive trees covers large coastal areas of land in Mediterranean regions, many of them characterized by low soil fertility and exposed to salinity and seasonal drought. In this frame, we developed mixed ... -
Co-composted biochar derived from rice straw and sugarcane bagasse improved soil properties, carbon balance, and zucchini growth in a sandy soil: A trial for enhancing the health of low fertile arid soils
(2022)Sustainable management of low fertile arid soils using carbon-rich organic amendments such as biochar and compost is of great concern from both agricultural and environmental points of view. The impact of pyrolysis, ... -
Effect of soil characteristics on shear strength of sands
(2018)The paper presents the results of a laboratory investigation into the influence of (a) mineral composition and angularity of sand grains and (b) fines type and content on the strength parameters of sandy soils tested at ... -
Numerical analysis of the seismic response of sand passively stabilized against liquefaction
(2015)Passive stabilization is a new technique for mitigating the risk of seismic liquefaction in the non-cohesive foundation soil of existing structures. It consists of the low pressure injection (in the soil pores) of colloidal ... -
Numerical Evaluation of Pile Response Under Combined Lateral and Axial Loading
(2018)Piled foundations are frequently subjected to simultaneous axial and lateral loadings. However, the interaction effects of the one loading on the other are, in most cases, disregarded for the sake of simplicity. With the ... -
Parametric investigation of lateral spreading of gently sloping liquefied ground
(2010)This paper investigates the main parameters affecting the anticipated maximum surface displacements due to earthquake-induced lateral spreading of mildly sloping ground. The main tool used for this purpose is a numerical ... -
Phenomenological simulation of the seismic response of ground stabilized with colloidal silica
(2014)Passive stabilization is a novel technique for mitigating the risk of seismic liquefaction in the non-cohesive foundation soil of existing structures. It entails the low-gradient injection of colloidal silica in the soil ... -
Prediction of cement suspension groutability based on sand hydraulic conductivity
(2020)The experimental investigation reported herein aims toward the development of groutability prediction models based on the hydraulic conductivity of sand and other parameters affecting the groutability of cement suspensions. ... -
Sand fabric evolution effects on drain design for liquefaction mitigation
(2011)This paper revisits the seminal work of Seed and Booker (1977) [21] on the design of infinitely permeable drains for liquefaction mitigation. It is shown that their basic mathematical assumption for the rate of earthquake-induced ... -
Simulation of soil water drainage in sandy soils, laid on a ceramic plate. Comparison with experimental data
(1998)In the present paper the simulation of water movement during vertical one dimensional drainage is presented. The study is referred to uniform sandy soil samples, laid on a ceramic plate of a very small saturation hydraulic ... -
Strong host-specific selection and over-dominance characterize arbuscular mycorrhizal fungal root colonizers of coastal sand dune plants of the Mediterranean region
(2021)Sand dunes of the Mediterranean region constitute drought-stressed, low-fertility ecosystems. Arbuscular mycorrhizal fungi (AMF) are regarded as key components of their biota, that contribute to plant host adaptation and ...
