Book Description
Soil moisture is a critical variable in the optimization of irrigation scheduling in water resources management. Despite using tens to hundreds of thousands of gallons of water each day, many golf courses rely on a sparse network of point measurements to estimate irrigation requirements for turfgrass management. This study describes a novel system known as Precision Irrigation Soil Moisture Mapper (PrISMM) in which an unmanned aerial vehicle equipped with multispectral sensors is used to estimate volumetric water content (VWC) at a golf course using a thermal inertia approach. PrISMM consists of three central components, including (1) highresolution thermal and optical remotely-sensed data, (2) site-specific soil analysis, and (3) surface energy balance modeling. The objective is to evaluate the feasibility of spatially-variable irrigation management for a golf course in north central Texas using PrISMM. Multispectral data are collected during the fall of 2017 in the visible, near infrared and longwave infrared (thermal) spectrum using a UAV capable of rapid and safe deployment for daily time-series estimates. Each data set consists of two flights collected on the same day, including a morning and midday flight. Diurnal temperature variations were then related to ground heat flux to derive thermal inertia. Using thermal and physical soil properties, thermal inertia estimates are converted to daily VWC estimates with a resolution of 8.6 cm. The accuracy of PrISMM is quantified using ground truthing with a time domain reflectometry soil moisture sensor. The model produces good estimates for VWC with an average coefficient of correlation of (r) = 0.89 and coefficient of determination of (R2 ) = 0.79. Findings from this study indicate that PrISMM offers superior spatial and temporal resolution compared to in situ methods and may be implemented to precisely irrigate urban landscapes, thus saving millions of gallons of water annually.

Book Description
Golf Turf Management provides information on major agronomic and economic topics related to building and maintaining a viable golf course. The book features basic and applied information on available grasses including selection and use; applied turfgrass physiology; soils and soil amendments; environmental concerns; and comprehensive information on turfgrass physiology, plant nutrition, turf fertilizers, and water management. It discusses managing turf diseases, insects, and weeds; turf cultural practices; managing greens and tees as well as corporate course management strategies. Color photographs throughout illustrate concepts and topics including all major pest problems associated with golf courses and various agronomic practices necessary for successful and profitable course operation. The book suggests strategies to develop best management practices for golf courses including personnel and financial considerations when developing and implementing annual budgets, leasing versus buying equipment, and managing inventory. This book features sixteen chapters organized in a logical sequence conducive for teaching and practical use. Drawing on the author's more than thirty years of experience and research, the author brings together a wealth of information on how to optimize golf turf management and performance. Golf Turf Management is the only complete, up-to-date text dedicated to agronomic practices and personnel management practices necessary for fiscal success.
