Book Description
Water is an increasingly valuable and limited resource, often perceived as being wasted on turfgrass. This much-anticipated second edition brings clear, current, science-based information on turfgrass management and water conservation to turf managers and researchers alike. Inside you’ll find a look at the current understanding of water use as well as new technologies being researched to reduce water use by turfgrass. Attention is paid to water quality and turfgrass as a key part of the urban environment, how integrating turfgrass with other landscape uses of water can be part of a conservation plan, and how various water qualities, including reclaimed water, can be part of a management plan. Chapters also cover •advances in drought, heat, and salinity stress tolerance •the role of water in modified root zone media and native soils •water management technologies •considerations for construction and management of urban green spaces including parks and golf courses •water depletion, pesticide and nutrient runoff A chapter summarizing the practical application of the science in each chapter rounds out the text, presenting the information in an immediately useable format. Includes 10 tables and figures, 20 color photos, a U.S. customary to metric conversion table, and an 8-page glossary.

Book Description
Reductions of water and nitrogen (N) inputs have long been important topics for sustainable turfgrass management. Facing rising challenges of water crises and climate change, more research is needed on such topics. With increasing city water shortages and water restrictions on turfgrasses in the U.S., it is important to research strategies to preserve C3 and C4 turfgrasses during prolonged drought. In addition, to guide the best irrigation and N-fertilization management strategies of turfgrass for the mitigation of global warming in this century, process-based models, such as DAYCENT and DeNitrification-DeComposition (DNDC), become important tools, which simulate nitrous oxide (N2O, an important greenhouse gas and ozone-depleting gas) and soil carbon sequestration. To find strategies for alleviating drought stress during prolonged drought with imposed water restrictions, the objectives in the first part of the dissertation were to (1) evaluate turfgrass performance during drought and recovery among irrigation levels, and (2) determine minimum water amounts for turfgrass during prolonged drought that allow for acceptable recovery. Two independent studies were conducted on C3 and C4 turfgrasses, respectively, using irrigation much lower than recommendation levels during 2 summers of drought under a rainout shelter. Results indicated that during severe drought and imposed water restrictions, minimal weekly irrigation of at least 20 to 30% reference evapotranspiration (ETo) and 40 to 50% ETo could reduce turfgrass damage and conserve water in zoysiagrass (C4; Zoysia japonica Steud., hereafter referred to as zoysia) and tall fescue (C3; Festuca arundinacea Schreb.), respectively. The failure of Kentucky bluegrass (C3; Poa pratensis L.) to survive extended drought was possibly related to being first-year sod. To inform and guide irrigation and N-fertilization management of turfgrass for global warming mitigation, the objectives of the second part of this dissertation were to 1) calibrate DAYCENT and DNDC for N2O emissions from Meyer zoysia; 2) validate and test the two calibrated models and compare their prediction accuracies; and 3) predict long-term N2O emissions, C sequestration, and global warming potential (GWP) of different irrigation and N-fertilization practices. A combination of global sensitivity analysis and a Bayesian method was used to calibrate DAYCENT and DNDC. After calibration, both models were validated using field measurements from two studies of zoysia. Validation results indicated DAYCENT (R2 = 0.22 to 0.89; relative RMSE = 36 to 171%) outperformed DNDC (R2 = 0.01 to 0.38; relative RMSE = 119 to 193%) in biweekly N2O fluxes. Annual N2O emission estimates obtained from validation of DAYCENT were within -49 to +26% of annual estimates interpolated from measurements, whereas DNDC simulations generally underestimated N2O emissions by up to -86%. Results indicated DAYCENT, but not DNDC, can adequately simulate the impacts of irrigation and N-fertilization practices on N2O emissions in C4 turfgrasses such as zoysia. When assuming no further climate change, the validated DAYCENT model predicted that the typically recommended N-fertilization and irrigation practice in fairway zoysia turf would reduce net GWP by encouraging soil carbon sequestration in the first 40 years of establishment, better than no N-fertilization, after which reducing N and water inputs would be beneficial in mitigating increases of N2O emissions and net GWP. A medium global warming scenario would accelerate increases in N2O emissions and GWP, especially with higher N and water inputs.

Book Description
The transition zone is the toughest area in which to maintain quality turf. It is a zone where temperature and precipitation vary greatly from season to season and where more intensive maintenance of seasonal grasses is required.This is the only book to cover the maintenance of intensive turfgrasses found in such zones. Easy to read and practical this book offers the superintendent or turf manager accessible information in a complex and difficult area. * This is the only book to cover the maintenance of intensive turfgrasses found in the transition zones * It addresses the basic science of growth cycles, nutrients and fertilisers, in an accessible way, so that that turf managers can easily locate and understand the information they need * It covers all aspects of cultural practices including mowing and irrigation * Features information on diseases and insects specific to the transition zone

Book Description
Written by three of the top professionals in the turfgrass field, Managing Turfgrass Pests, Second Edition brings together hundreds of solutions and best practices to help you manage turfgrass weeds, diseases, and insects more effectively. Since the publication of the bestselling first edition, advances in pest-resistant turfgrass cultivars and pest control products have led to significant changes in the ways pests are managed. This revised and updated second edition reinforces those management tactics that are still relevant and covers new approaches that have been introduced since the first edition. The book discusses the concept of integrated pest management, incorporating cultural, biological, and chemical control measures. In particular, the authors emphasize the philosophy of minimizing pests through well-defined and well-implemented cultural systems. Rather than simply relying on a pesticide solution for control, they explain how to fine-tune cultural practices to better address the question of why the pest is present in the first place. Once these cultural practices are in place, any pesticide that is still required will be much more effective at controlling the pest. New in This Edition Revised and updated descriptions of economically important turfgrass pests Revised and updated cultural approaches to turfgrass pest management Revised and updated biological methods of turfgrass pest management Revised and updated chemical control of turfgrass pests More than 200 new color illustrations Packed with photographs, this full-color book provides updated information on best practices and control measures for turfgrass pest management. It also explains how to integrate various management strategies to ensure quality and functional turf. Throughout, the authors offer practical recommendations to help you optimize the competitiveness of your turfgrass against the pests that inevitably become part of any ecosystem.
