226. Synchrotron and Conventional Analyses of Soil Pore Properties Influencing Cohesion in Coastal Tablelands Soils

(MS02) Porous Media for a Green World: Water & Agriculture

Oral Presentation

Many soils in the Coastal Tablelands of Brazil have limitations in their physical quality because of subsurface cohesive horizons [1]. The consistency of cohesive soil horizons is hard to extremely hard when dry, restricting root development, while its structure slakes under high water content, reducing the support of plants and drainage [2,3]. Often, sand constitutes 70% to 80% of cohesive...

419. Exploring Water Transport and Aging Mechanisms in Bio-Based Porous Materials through NMR Relaxometry

(MS02) Porous Media for a Green World: Water & Agriculture

Oral Presentation

Aluminosilicate-based materials, such as geopolymers, have attracted significant attention due to their diverse industrial applications in catalysis, adsorption, and wastewater treatment. Among these materials, aluminosilicate hydrogels, precursors to zeolites, show great promise for advancing sustainable materials. These hydrogels are capable of enhancing soil stabilization and reducing...

434. Quantifying water flow across and hydraulic conductivity of the rhizosphere in coarse-textured soils using high-resolution X-ray CT

Oral Presentation

Plants are major drivers of terrestrial water fluxes, transpiring 40% of the global terrestrial precipitation. This vast amount of water inevitably flows through the rhizosphere, the thin soil layer surrounding roots. This interface is, therefore, of great relevance for the hydrological cycle. Especially when considering coarse-textured soils such as sandy soils, existing soil-plant models...

516. Modelling and Model Validation Methods for Porous Media Solute Flow Problems

(MS02) Porous Media for a Green World: Water & Agriculture

Oral Presentation

In this talk I will outline combined experimental approach my group has taken to quantify porous media, such as soil, solute movement, such as plant nutrient P, movement using high temporal resolution techniques.

The reason for focusing on phosphorus is that it is an essential nutrient for crops. Precise spatiotemporal application of P fertilizer can improve plant P acquisition and reduce...

94. Microfluidics-based experimental study of the use of yield stress fluids to improve organic pollutant removal from contaminated soils

(MS02) Porous Media for a Green World: Water & Agriculture

Oral Presentation

Urban and agricultural environments are increasingly contaminated by chlorinated solvents, pesticides, nitrates, heavy metals, etc. Such pollutants, which initially impact surface soils, eventually seep into groundwater. It is therefore essential to remediate degraded soils to ensure water and food sovereignty. This study presents a method for remediating soils contaminated by organic...

411. Development of an Integrated Biofilm NMR Microplastic Sensor for Agricultural Water Monitoring

Prof. Joseph Seymour (Montana State University)

(MS02) Porous Media for a Green World: Water & Agriculture

Oral Presentation

A laboratory investigation aimed at understanding the interaction between model environmental biofilms and water quality contaminants such as metals and microplastics is developed. Microbial biofilms can adsorb and retain water-born contaminants in their matrix of extracellular biopolymers, which form a hydrogel called EPS, and therefore have potential to capture evidence of transient...
