Book Description
Evapotranspiration and its components (evaporation and transpiration) as a process is one of the basic terms of Earth's water balance; its importance is accented by the fact that transpiration is the vital element of the biomass production process. The second important property of evapotranspiration is its extreme consumption of solar energy, thus controlling the temperature of the atmosphere and creating favourable conditions for life. Evapotranspiration as an energy consuming process is also the connection between the energy and mass cycles of the Earth. Evapotranspiration is a process performing in the Soil–Plant –Atmosphere System (SPAS); therefore this book is presenting and quantifying it as a catenary process, describing transport of water in the soil, including root extraction patterns and methods of its evaluation. Transport of water through the plant and from the canopy to the atmosphere is also described and quantified. A variety of evapotranspiration (and its components evaporation and transpiration) calculation methods are described, starting from empirical methods up to the most sophisticated ones based on the solution of the transport equations of water and energy in the SPAS. The most important (and widely used) calculation method - modified Penman–Monteith method is described in details, ready to be used with data in the book only. Water balance method of evapotranspiration estimation as well as sap flow method description can be found in the book as well. The book can be used by hydrologists, biologists, meteorologists and other specialists as well as by ecology students. Key themes: soil hydrology – evapotranspiration – hydropedology– plant physiology – water movement in soils – evaporation – transpiration Dr. Viliam Novák is a water resources scientist at the Institute of Hydrology of the Slovak Academy of Sciences in Bratislava (Slovakia).

The Role of Plant Roots in Crop Production
Author: Nand Kumar FageriaPublisher: CRC Press
ISBN: 1439867372
Category : Science
Languages : en
Pages : 471
Book Description
The Role of Plant Roots in Crop Production presents the state of knowledge on environmental factors in root growth and development and their effect on the improvement of the yield of annual crops. This book addresses the role of roots in crop production and includes references to numerous annual crops. In addition, it brings together the issues and the state-of-the-art technologies that affect root growth, with comprehensive reviews to facilitate efficient, sustainable, economical, and environmentally responsible crop production. Written for plant scientists, crop scientists, horticulturalists, and soil scientists, plant physiologists, breeders, environmental scientists, agronomists, and undergraduate and graduate students in different disciplines of agricultural science, The Role of Plant Roots in Crop Production: Addresses root architecture and development dynamics to help users improve crop productivity Emphasizes crop production, plant nutrition, and soil chemistry relative to root growth and functions Covers root morphology, root functions, nutrient and water uptake by roots, root-soil interactions, root-environment interactions, root-microbe interactions, physiology of root crops, and management practices to improve root growth Supports content with experimental results, and additional data is presented with pictures Increasing food production worldwide has become a major issue in the 21st century. Stagnation in grain yield of important food crops in recent years in developed, as well as developing, countries has contributed to a sharp increase in food prices. Furthermore, higher grain yield will be needed in the future to feed a burgeoning world population with a rising standard of living that requires more grain per capita. Technologies that enhance productivity, ensure environmental safety, and conserve natural resources are required to meet this challenge.

Author: These Roots Remain
Author: Nancy J. PollockPublisher:
ISBN:
Category : Social Science
Languages : en
Pages : 328
Book Description
The author finds that food comprises a carefully categorized set of symbols that help determine thought and action in Pacific societies. Food is a culture pattern, unique to each society. But some patterns are also shared and those shared patterns are due to links in times past. Pollock investigates the cultural mechanisms that have allowed certain distinct features associated with food to remain in the face of many intrusions to those societies. Extensively reviewed are the sociocultural, archeological-historical, and scientific literature on the topic, ranging from the records of early explorers, missionaries, and pioneer ethnographers to those of modern medical, nutritional, and ethnobotanical researchers, along with observations from the author's personal fieldwork.
