Download or read book Monitoring and Predicting Agricultural Drought written by Vijendra K. Boken and published by Oxford University Press. This book was released on 2005-04-14 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural droughts affect whole societies, leading to higher food costs, threatened economies, and even famine. In order to mitigate such effects, researchers must first be able to monitor them, and then predict them; however no book currently focuses on accurate monitoring or prediction of these devastating kinds of droughts. To fill this void, the editors of Monitoring and Predicting Agricultural Drought have assembled a team of expert contributors from all continents to make a global study, describing biometeorological models and monitoring methods for agricultural droughts. These models and methods note the relationships between precipitation, soil moisture, and crop yields, using data gathered from conventional and remote sensing techniques. The coverage of the book includes probabilistic models and techniques used in America, Europe and the former USSR, Africa, Asia, and Australia, and it concludes with coverage of climate change and resultant shifts in agricultural productivity, drought early warning systems, and famine mitigation. This will be an essential collection for those who must advise governments or international organizations on the current scope, likelihood, and impact of agricultural droughts.

Download or read book Applications of Soil Physics written by Daniel Hillel and published by Elsevier. This book was released on 2012-12-02 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Applications of Soil Physics deals with the applications of soil physics and covers topics ranging from infiltration and surface runoff to groundwater drainage, evaporation from bare-surface soils, and uptake of soil moisture by plants. Water balance and energy balance in the field are also discussed, along with tillage and soil structure management. The development and extension of Penman's evaporation formula is also described. This book is comprised of 14 chapters and begins with a systematic description of the field-water cycle and its management, with emphasis on infiltration and runoff; redistribution and drainage; evaporation and transpiration; and irrigation and tillage. Subsequent chapters focus on transpiration from plant canopies; freezing phenomena in soils; scaling and similitude of soil-water phenomena; spatial variability of soil physical properties; and movement of solutes during infiltration into homogeneous soil. Concepts of soil-water availability to plants are considered, together with principles of irrigation management and the advantages and limitations of drip irrigation. This monograph is intended for upper-level undergraduate and graduate students of the environmental, engineering, and agronomic sciences.

Download or read book Assessment of Intraseasonal to Interannual Climate Prediction and Predictability written by National Research Council and published by National Academies Press. This book was released on 2010-10-08 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: More accurate forecasts of climate conditions over time periods of weeks to a few years could help people plan agricultural activities, mitigate drought, and manage energy resources, amongst other activities; however, current forecast systems have limited ability on these time- scales. Models for such climate forecasts must take into account complex interactions among the ocean, atmosphere, and land surface. Such processes can be difficult to represent realistically. To improve the quality of forecasts, this book makes recommendations about the development of the tools used in forecasting and about specific research goals for improving understanding of sources of predictability. To improve the accessibility of these forecasts to decision-makers and researchers, this book also suggests best practices to improve how forecasts are made and disseminated.

Download or read book Moisture Strength Constructability Guidelines for Subgrade Foundation Soils Found in Indiana written by Eshan Ganju and published by Joint Transportation Research Program. This book was released on 2017-02-28 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil moisture is an important indicator of constructability in the field. Construction activities become difficult when the soil moisture content is excessive, especially in fine-grained soils. Change orders caused by excessive soil moisture during construction projects drive up construction costs for INDOT and cause unexpected delays. To alleviate these problems and minimize change order costs associated with unexpectedly high soil moisture conditions at the time of construction, a methodology was developed to allow INDOT engineers to estimate in situ soil moisture conditions early in the design phases of projects. The soil moisture prediction methodology is based on results from soil moisture flow simulations carried out using the HYDRUS-1D software. The soil moisture flow simulations in HYDRUS-1D required i) weather data, ii) groundwater table data and iii) in situ soil hydraulic (saturated and unsaturated) and index property data. These data were collected for all the counties in Indiana from five different sources: i) Indiana Department of Transportation (INDOT), ii) Indiana Geological Survey (IGS), iii) United States Department of Agriculture's (USDA's) Soil Survey Geographic (SSURGO), iv) the Department of Natural Resources (DNR) and v) Indiana State Climate Office (Iclimate). The results obtained from initial soil moisture flow simulations were first validated using field measurements from six IGS test sites located in Indiana where soil property data and continuous in situ soil moisture measurements at multiple depths were available for up to 3 years (2011-2014). Then, ten-year moisture content simulations using HYDRUS 1D were performed for typical profiles in each county in Indiana using as input weather data from the iclimate database, groundwater data from DNR database and soil properties from IGS, INDOT and the SSURGO databases. Yearly results from these ten-year soil moisture flow simulations were then overlapped to ascertain how the profiles of the in situ soil moisture content within the depth of interest varied monthly within this period of time in each county. Recommendations are made for in situ soil moisture constructability assessment that can be implemented by INDOT in pilot projects and further refined as needed.

Download or read book Prediction of Soil Moisture from Soil and Weather Records written by ARMY ENGINEER WATERWAYS EXPERIMENT STATION VICKSBURG MISS. and published by . This book was released on 1959 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of a study to develop means of estimating the ability of soils to permit vehicular traffic, a method was developed for predicting the moisture content of soils. Data used in development of the method were obtained from daily soil moisture and weather records kept for periods of one to two years at 131 sites throughout the United States. Chief influences on moisture accretion in the surface foot of soil were found to be the amount of rainfall and the amount of space available in the soil for water storage. Moisture depletion rates varied with the moisture content of the soil but followed characteristic curves for each season. The prediction method was tested on more than 600 sites throughout the United States.

The tedious farming tasks had been taken over by agricultural machines in last century, in new millennium, computer-aided systems, automation, and robotics has been applied to precisely manage agricultural production system. With agricultural automation technologies, sustainable agriculture is being developed based on efficient use of land, increased conservation of water, fertilizer and energy resources. The agricultural automation technologies refer to related areas in sensing & perception, reasoning & learning, data communication, and task planning & execution. Since the literature on this diverse subject is widely scattered, it is necessary to review current status and capture the future challenges through a comprehensive monograph. In this book we focus on agricultural automation and provide critical reviews of advanced control technologies, their merits and limitations, application areas and research opportunities for further development. This collection thus serves as an authoritative treatise that can help researchers, engineers, educators, and students in the field of sensing, control, and automation technologies for production agriculture.
