Water Conservation Practices for Irrigation of Turfgrass Lawns
… objectives: 1) evaluate the use of rain and soil moisture sensors in a humid transition zone environment; 2) evaluate the effects of chronic drought stress between drought-resistant and drought-sensitive varieties of tall fescue (Festuca arundinacea Schreb.; TF) and Kentucky bluegrass (Poa …

Hydrologic Response to Conifer Removal and Upslope Harvest in an Encroached Montane Meadow
… plan implemented by the Collins Pine Company. Soil moisture sensors at one foot below the ground and water table depth sensors at four feet below ground were installed in Marian Meadow and a control meadow in September 2013, with additional soil moisture sensors at three-foot depth installed …

Real-time control of soil moisture for efficient irrigation
… at a predetermined rate, duration, and minimum soil moisture. Due to the ease of installation of soil moisture sensors, this technology has been installed around the world. There have been few studies on altering the controller used with this existing infrastructure. This thesis articulates a …

Use Patterns and Influencing Factors of Irrigation Best Management Practices in the Lower Mississippi River Basin
… and advanced irrigation scheduling practices (soil moisture sensors, ET or atmometers, computerized scheduling, and Woodruff charts). We find that most of the sample producers use between one and four individual IBMPs from two or more groups. Explanatory variables consist of producer …

EVALUATION OF BEDROCK DEPTH AND SOIL INFILTRATION ALONG PENNYPACK CREEK USING ELECTRICAL RESISTIVITY TOMOGRAPHY AND MOISTURE LOGGERS
… the drivers of hydraulic processes, such as soil characteristics, bedrock depth, and land use, the quality and accuracy of models can be improved. The goal of this study was to use soil moisture loggers and electrical resistivity tomography (ERT) along the Pennypack Creek (Philadelphia, PA) …

Improving Soil Moisture Assessment of Turfgrass Systems Utilizing Field Radiometry
… 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. Remotely sensed data such as the normalized difference vegetation index (NDVI) offer …

The Water Table and Soil Moisture Response Following the Removal of Conifers from an Encroached Meadow
… While multiple studies have assessed changes in soil structure and vegetation composition, few studies directly investigate changes in hydrology following meadow conifer removal projects. The goal of this study is to determine if the removal of conifers from an encroached meadow (Marian Meadow) …

The Water Table, Soil Moisture and Evapotranspiration Conditions Following the Removal of Conifers from Two Encroached Meadows
… on depth to the groundwater table (WTD) and soil moisture content (SMC), and to investigate the accuracy and potential usefulness of evapotranspiration (ET) calculation methodologies for montane meadows. This goal will be accomplished by the subsequent objectives: 1) perform an analysis of …

Data-driven modeling of hydroclimatic trends and soil moisture: multi-scale data integration and decision support
… recognize the heterogeneity of hydroclimatic and soil characteristics throughout the United States. Machine learning algorithms modeling the wetting/drying process must address this variability, and yet it is wholly impractical to construct a separate algorithm for every conceivable location. For …

Producer Preferences for Alternative Irrigation Practices in the Arkansas Delta
<p>We use a bivariate sample selection model to address peer network effects on participation in and/or intensity of use of land being irrigated by alternative irrigation practices in the state of Arkansas. As groundwater in the state becomes more limited, the use of scientific scheduling, …
