Remediation of Soil Hydrophobicity on a Coastal USGA Sand-Based Golf Green
… superintendents and managers, especially as water restrictions intensify. The purpose of this study was to evaluate the effectiveness of thirteen soil surfactants in eliminating LDS and in maximizing root zone soil moisture on a sand based USGA golf green located on the California Central …

Correlation Analyses among Soil, Plant, and Environmental Variables and Greenhouse Gas Emissions from Furrow-irrigated Rice on a Silt-loam Soil
<p>Alternative water management practices for rice (Oryza sativa) production have been developed for water conservation purposes, such as the relatively new furrow-irrigated rice production system, which results in spatially variable volumetric water content (VWC), temperature, and …

EXTENSIVE GREEN ROOF SUBSTRATE COMPOSITION: EFFECTS OF PHYSICAL PROPERTIES ON MATRIC POTENTIAL, HYDRAULIC CONDUCTIVITY, PLANT GROWTH, AND STORMWATER RETENTION IN THE MID-ATLANTIC.
… (GR) systems have gained popularity as storm water management tools, more emphasis has been applied to studying performance aspects, including stormwater retention. Of particular importance is the substrate layer in which the vegetation grows, which contributes the majority of stormwater …

Adaptive Silviculture in an urban floodplain forest: exploring functional traits and soil responses for climate ready forests
… we have measured the photosynthetic performance, water relations, and foliar nutrients of the individuals and communities in the experiment. In addition to exploring tree ecophysiology, we also measured soil moisture and temperature dynamics at multiple depths to assess whether the experimental …

Improving Soil Moisture Assessment of Turfgrass Systems Utilizing Field Radiometry
The need for water conservation continues to increase as global freshwater resources dwindle. In response, many golf course superintendents are implementing new methods and tools to become more frugal with their water applications. For example, scheduling irrigation using time-domain reflectometer …

Bridging the Gap Between Lidar, Thermal, and Multispectral Remote Sensing for Irrigation Scheduling Applications
… Prairies is a semi-arid landscape with limited water resource availability, requiring careful application of water management practices. This thesis studies methods to reduce irrigation water consumption in agricultural fields with complex soil texture dynamics using the water deficit index …

Development of Urban Tree Growth Models Based on Site and Soil Characteristics
… high (0.85) coefficients of determination when volumetric water content (VWC) was log transformed, demonstrating that measurements of soil texture, strength, and moisture can provide rapid, reliable assessment of soil compaction. Tree growth modeling focused on three response variables: canopy …

Optimizing Corn and Cotton Performance with Adaptive Management Systems and Subsurface Drip Irrigation in the Mid-Atlantic USA
… three years the 0.91 m dripline and 0.91 m with volumetric water content (VWC) sensors increased revenue by $985 and $885 ha-1, respectively, above non-irrigated. Grain yield increased up to a seeding rate of 88,920 plants ha-1 and N rates up to 267 kg N ha-1. The third study utilized two …

STORMWATER MANAGEMENT PRACTICE MONITORING USING LONG-TERM TIME LAPSE ELECTRICAL RESISTIVITY TOMOGRAPHY AND SOIL SENSORS: IMPLICATIONS FOR DESIGN, MAINTENANCE, AND SOIL MOISTURE MONITORING
… local laws, PennDOT must account for the stormwater runoff and minimize outflow to the sewer system. To do so, PennDOT has plans to construct a series of stormwater management practices (SMPs) adjacent to I-95 to control the volumes of highway runoff. In partnership with Villanova University, …
