In order to examine whether the electrolyte concentration in the soil solution can be estimated by time domain reflectometry (TDR) measured bulk soil electrical conductivity, column leaching experiments were performed using undisturbed soil columns during unsaturated steady-state water flow.

One was the strongly structured Ramiha silt loam, and the other the weakly structured Manawatu fine sandy loam.

Soybean production in Iowa USA is among the most productive for rainfed regions in the world.

Abstract. Soil salinity and sodicity caused by saline water irrigation are widely observed globally. Clay dispersion and swelling are influenced by sodium (Na+) concentration and electrical conductivity (EC) of soil solution. Specifically, soil potassium (K+) also significantly affects soil structural stability, but for which concern was rarely addressed in previous studies or irrigation practices. A soil column experiment was carried out to examine the effects of saline water with different relative concentrations of K+ to Na+ (K+ / Na+), including K+ / Na+ of 0:1 (K0Na1), 1:1 (K1Na1) and 1:0

For example, scheduling irrigation using time-domain reflectometer (TDR) soil moisture sensors can decrease water usage. Still, TDR measurements are time-consuming and only cover small scales, leading to many locations being unsampled.

The inaccessibility and cost of soil testing reduce effectiveness of fertilizer use on small-scale subsistence farms, and inadequate funding promotes adoption of soil tests in developing countries with minimal validation.

Abstract:
Abstract Currently, we are developing protocols for cryopreserving select strains of algae from a large culture collection. Protocol design processes for specific organisms involve modeling the coupled osmomechanical behavior of the cells during cryoprotective additive (CPA) exposure. Perfusion cryomicroscopy experiments were conducted to characterize the extent of elastic and osmotic coupling effects upon cell volume changes during exposure of Chlorococcum texanum to step changes in extracellular sucrose concentration. Volume data obtained off-line from video recordings of continuous volumetr

Abstract Thousands of kilometers of pipelines are being utilized to transport produced water among different regions in the Kingdom of Saudi Arabia. Underground pipelines, carrying produced water, are externally subjected to different types of soil. In order to protect them, an external coating and internal cement lining are applied. Produced water had fixed parameters quality range for long periods of time. Decisions were made to increase the concentration of total dissolved solids (TDS) of the produced water from 130 ppm to 300 ppm plus. An increase in TDS of produced water would raise chlor

Abstract:
Abstract Aluminum-based alloys are widely used in sea water as galvanic anodes. Conversely, their use in soil is not recommended because they tend to passivate when chloride content is low. However, there are chloride contaminated soil where the use of aluminum anodes may be of interest. The aim of this research is to evaluate the effectiveness of aluminum galvanic anodes in low salinity solutions at different chloride/sulfate ratios. The research followed two phases: electrochemical characterization of anodes through potentiodynamic and free corrosion potential tests in solution with differen

Abstract:
Abstract A close coupled mixed metal oxide (MMO) anode, grid or concentric ring, cathodic protection (CP) system is a state-of-the-art technique for corrosion prevention of the soil-side bottom of an aboveground storage tank (AST) resting on sand pads. The regulatory requirement of secondary containment for ASTs, especially with the use of polyethylene liners, has eliminated the use of traditional shallow anodes around the periphery or the deep well anode systems. Recent experiences with close coupled CP systems have shown that adequate corrosion protection is not achieved for ASTs and are sub

Abstract:
Abstract Degradation of buried piping is a large concern for numerous industries including nuclear, oil and gas, waste water, etc. Current condition assessment is an important part of the life cycle management of aging pipelines and includes assessment of the external surface, indirect inspection, direct examination, and post-assessment. Measurement of soil parameters can help determine highest risk location where corrosion may be occurring. For measuring corrosion rates in soils, electrical resistance probes, linear polarization resistance probes, and corrosion coupons are commonly employed.

Full text
Abstract:
Concentrated flow erosion in rills, pipes, ephermal gullies, and gullies is a major contributor of downstream sedimentation. When rill or gullies form in a landscape, a 3- to 5-fold increase in soil loss commonly occurs. The balance between the erosive power of the flow and the erosion resistance of the bed material determines the rate of concentrated flow erosion. The resistance of the bed material to detachment depends primarily on the magnitude of the interparticle forces or cohesion holding the particles and aggregates together.

Abstract:
A semi-empirical elasto-plastic constitutive model with a hyperbolic stress-strain curve was developed with the goal of predicting the seismic compression of unsaturated sands in the funicular regime of the soil-water retention curve (SWRC) during undrained cyclic shearing. Using a flow rule derived from energy considerations, the evolution in plastic volumetric strain (seismic compression) was predicted from the plastic shear strains of the hysteretic hyperbolic stress-strain curve. The plastic volumetric strains are used to predict the changes in degree of saturation from phase relationships

Abstract:
The overall goal of this project was to elucidate the role of dissolved organic matter (DOM) in soil retention, bioavailability and plant uptake of silver and cerium oxide NPs. The environmental risks of manufactured nanoparticles (NPs) are attracting increasing attention from both industrial and scientific communities. These NPs have shown to be taken-up, translocated and bio- accumulated in plant edible parts. However, very little is known about the behavior of NPs in soil-plant system as affected by dissolved organic matter (DOM). Thus DOM effect on NPs behavior is critical to assessing the

Abstract:
The ability to detect and classify buried objects using thermal infrared imaging is affected by the environmental conditions at the time of imaging, which leads to an inconsistent probability of detection. For example, periods of dense overcast or recent precipitation events result in the suppression of the soil temperature difference between the buried object and soil, thus preventing detection. This work introduces an environmentally informed framework to reduce the false alarm rate in the classification of regions of interest (ROIs) in thermal IR images containing buried objects.

Full text
Abstract:
Preferential flow is the process whereby water and solutes move by preferred pathways. During preferential flow, local wetting fronts propagate to considerable depths in the soil profile, essentially bypassing the matrix pore space. Under such conditions classical methods, such as the convective-dispersive equation, for quantifying flow of water and solutes in uniform soils are not valid. This project set out to develop methods to predict fast and early breakthrough of solutes. To facilitate understanding of these processes, several field drainage studies were conducted in the United States an

Abstract:
Standard salinity management theory, derived from blending thermodynamic and semi- empirical considerations leads to an erroneous perception regarding compensative interaction among salinity stress factors. The current approach treats matric and osmotic components of soil water potential separately and then combines their effects to compute overall response. With deficit water a severe yield decrease is expected under high salinity, yet little or no reduction is predicted for excess irrigation, irrespective of salinity level.

In this study, replicable large-scale tests were used to analyze the ability of products to prevent sediment from exiting the perimeter of a site via sheet flow.
