Characterization of hydrologic parameters and processes in shrink-swell clay soils

Creator:: Stewart, Ryan D.
Abstract:: Vertisols and other vertic-intergrade soils are found all over the globe, including many agricultural and urban areas. These soils are characterized by their cyclical shrinking and swelling behaviors, where bulk density and porosity distribution both vary as functions of time and/or soil moisture. In turn, alterations in physical soil parameters...

The Soil Moisture Active Passive Marena, Oklahoma, In Situ Sensor Testbed (SMAP-MOISST): Testbed Design and Evaluation of In Situ Sensors

Creator:: Cosh, Michael H., Ochsner, Tyson E., McKee, Lynn, Dong, Jingnuo, Basara, Jeffrey B., Evett, Steven R., Hatch, Christine E., Small, Eric E., Steele-Dunne, Susan C., Zreda, Marek, and Sayde, Chadi
Abstract:: n situ soil moisture monitoring networks are critical to the development of soil moisture remote sensing missions as well as agricultural and environmental management, weather forecasting, and many other endeavors. These in situ networks utilize a variety of sensors and installation practices, which confounds the development of a unified reference...

Lime application effects on soil aggregate properties: Use of the mean weight diameter and synchrotron-based X-ray mu CT techniques

Creator:: Ferreira, Talita R., Pires, Luiz F., Wildenschild, Dorthe, Brinatti, Andre M., Borges, Jaqueline A. R., Auler, Andre C., and dos Reis, Aline M. H.
Abstract:: The hierarchical organization of aggregates in soil is responsible for the presence of inter and intra-aggregate pores. This research aimed to investigate effects of soil surface liming, considering lime rates of 0, 10 and 15 t ha(-1), on the intra-aggregate porous system of soil aggregates with equivalent diameters of 2-4...

Soil Development and Organic Carbon Stocks Across a Lithosequence in the Perhumid Coastal Temperate Rainforests of Southeast Alaska

Creator:: Fedenko, Jennifer M.
Abstract:: The perhumid coastal temperate rainforests of southeast Alaska contain an abundance of soil organic carbon (SOC) that has accumulated in a wet, cool climate where forest fire disturbance is minimal and organic matter decomposition rates are low. Coastal temperate rainforests are supported by carbon-rich soils that provide ecosystem services including...

Estimating Lime Requirement for Oregon Soils with Non-Hazardous Soil Test Methods

Creator:: Makepeace, Carl A.
Abstract:: Various soil tests are routinely used in the United States to predict soil lime requirement. New non-hazardous methods have recently been proposed for adoption in Oregon, however the accuracy of these methods for Oregon soils has not been established. The objectives of this investigation were: (a) to document and describe...

Relationship of Soil Fungal Communities and Burn Severity to Post-Fire Vegetation Response

Creator:: Roach, Skylar K.
Abstract:: The effects of fire on above-ground forest systems have been extensively studied. However, research on fire effects on belowground processes is lacking. While the soil microbiome is understood to be vital to conifer growth and regeneration, the complexity of soils means that research on the topic has largely been accomplished...

Monitoring Onion Thrips Response to Insecticide Agri-Mek SC in the Treasure Valley of Eastern Oregon and Western Idaho

Creator:: Flores Elizondo, Dennet
Abstract:: Onion thrips (Thrips tabaci) are pests found in onion fields of the Treasure Valley, which is located in Eastern Oregon and Western Idaho. Thrips cause damage to this high value crop by feeding on the onion’s extracellular fluid, making photosynthesis more difficult to occur. The feeding from the thrips can...

Estimation of Soil Particle Size Distribution using CT Scans

Creator:: Boath, Max E.
Abstract:: Remote sensing techniques have been applied extensively in geospatial investigations, but their use in measuring soil physical attributes has been far less explored. Soil particle size distributions (PSD) are indispensable in modeling pedological and hydrological processes as well as biodiversity. However, estimation of PSD via gravimetric measurement methods, the standard...

Calibration of soil moisture sensing with subsurface heated fiber optics using numerical simulation

Creator:: Benítez‐Buelga, Javier, Rodríguez‐Sinobas, Leonor, Sánchez Calvo, Raul, Gil‐Rodríguez, Maria, Sayde, Chadi, and Selker, John S.
Abstract:: The heat pulse probe method can be implemented with actively heated fiber optics (AHFO) to obtain distributed measurements of soil water content (θ) by using reported soil thermal responses measured by Distributed Temperature Sensing (DTS) and with a soil-specific calibration relationship. However, most reported applications have been calibrated to homogeneous...

Soil Health and the Response of the Soil Microbial Community to Disturbances across Western North America

Creator:: Kersey, Jordan H.
Abstract:: Temperate coniferous forests, such as those that cover vast areas of the western US and Canada, have evolved to depend on cycles of disturbance for succession of species and overall ecosystem maintenance. Many of these forest systems are managed, often for timber production, where disturbances are of anthropogenic origin and...
