Download or read book Monitoring Soil Moisture for Irrigation Water Management written by Blaine Hanson and published by University of California, Agriculture and Natural Resources. This book was released on 2007 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring soil moisture is an alternate method to water-based balance methods of managing irrigation water. Using this method you can "see" what is going on in the soil and determine answers to some key irrigation management questions: Did enough water infiltrate the soil? Is too much water being applied? What is the water uptake pattern of the roots? When should irrigation take place? What was the depth reached by the irrigation? Includes 24 figures and 7 tables, metric conversions, and an appendix of typical root depths. One of a series of water management handbooks prepared by the UC Irrigation Program.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil moisture sensors used to monitor the soil water status are one of the keys to delivering the right amount of water at the right time to satisfy crop water requirements. However, installation, calibration, and maintenance of soil moisture sensing devices and interpretation of data are complicated and tedious for most farmers. Furthermore, the variability, heterogeneity, and complexity of soils and how that interacts with individual soil moisture sensors and those sensors' installation results in inaccurate soil moisture information. The research aims to analyze the soil moisture data signals to estimate field capacity from soil moisture dynamics to assess the field capacity (FC) or "full point" and management allowable deficit (MAD) or "refill point" for irrigation management. The objectives of the research are to use soil moisture dynamics alone to estimate FC (full point) and MAD (refill points) for irrigation management; and to describe best practices for using soil moisture sensors alone to quantify ET and as well as some of the challenges. Results show that the developed algorithm, with simple interpretation and easy calculation, defines FC values from the soil water content sensor data that were reasonable as verified using data from soil water potential sensors co-located with the soil water content sensors. Using the method of estimating field capacity and literature values of FC, PWP, and MAD by different soil textures, we can also identify a usable refill point of the soil. Lastly, there are large uncertainties and inherent variabilities in measuring the consumptive use, or evapotranspiration (ET), using the soil water balance come from the uncertainties and unknowns in measuring deep percolation and capillary rise, and from installation, inaccuracies, and interpretation of soil water content sensors.0́3.

This book was released on 2012-03-09 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food security emerged as an issue in the first decade of the 21st Century, questioning the sustainability of the human race, which is inevitably related directly to the agricultural water management that has multifaceted dimensions and requires interdisciplinary expertise in order to be dealt with. The purpose of this book is to bring together and integrate the subject matter that deals with the equity, profitability and irrigation water pricing; modelling, monitoring and assessment techniques; sustainable irrigation development and management, and strategies for irrigation water supply and conservation in a single text. The book is divided into four sections and is intended to be a comprehensive reference for students, professionals and researchers working on various aspects of agricultural water management. The book seeks its impact from the diverse nature of content revealing situations from different continents (Australia, USA, Asia, Europe and Africa). Various case studies have been discussed in the chapters to present a general scenario of the problem, perspective and challenges of irrigation water use.
Download or read book Irrigation Scheduling written by Jennifer Laffan and published by NSW Agriculture. This book was released on 2015-12-01 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scheduling irrigation is about planning when and how much water to apply to a crop to achieve crop production or a particular quality. The principles of scheduling water apply to all crops, however the critical timing, methods and techniques can vary with the crop. This book is about: · the ways in which specific crops respond to stress and the effects of the timing and degree of stress and the growth stage of the crop · evapotranspiration (ET) and crop water use to schedule irrigations · developing an irrigation schedule · terms used to describe the amount of water available to a crop · soil moisture probes and where to locate them · water quality issues to consider.

Download or read book Agricultural Water Management written by National Research Council and published by National Academies Press. This book was released on 2007-03-20 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains a collection of papers from a workshopâ€"Strengthening Science-Based Decision-Making for Sustainable Management of Scarce Water Resources for Agricultural Production, held in Tunisia. Participants, including scientists, decision makers, representatives of non-profit organizations, and a farmer, came from the United States and several countries in North Africa and the Middle East. The papers examined constraints to agricultural production as it relates to water scarcity; focusing on 1) the state of the science regarding water management for agricultural purposes in the Middle East and North Africa 2) how science can be applied to better manage existing water supplies to optimize the domestic production of food and fiber. The cross-cutting themes of the workshop were the elements or principles of science-based decision making, the role of the scientific community in ensuring that science is an integral part of the decision making process, and ways to improve communications between scientists and decision makers.
Download or read book Modelling and Management of Irrigation System written by Juan Antonio Rodríguez Díaz and published by MDPI. This book was released on 2020-04-30 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation is becoming an activity of precision, where combining information collected from various sources is necessary to optimally manage resources. New management strategies, such as big data techniques, sensors, artificial intelligence, unmanned aerial vehicles (UAV), and new technologies in general, are becoming more relevant every day. As such, modeling techniques, both at the water distribution network and the farm levels, will be essential to gather information from various sources and offer useful recommendations for decision-making processes. In this book, 10 high quality papers were selected that cover a wide range of issues that are relevant to the different aspects related to irrigation management: water source and distribution network, plot irrigation systems, and crop water management.
Download or read book Earth Observation for Water Resources Management written by Luis García and published by World Bank Publications. This book was released on 2016-04-14 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water systems are building blocks for poverty alleviation, shared growth, sustainable development, and green growth strategies. They require data from in-situ observation networks. Budgetary and other constraints have taken a toll on their operation and there are many regions in the world where the data are scarce or unreliable. Increasingly, remote sensing satellite-based earth observation is becoming an alternative. This book briefly describes some key global water challenges, perspectives for remote sensing approaches, and their importance for water resources-related activities. It describes eight key types of water resources management variables, a list of sensors that can produce such information, and a description of existing data products with examples. Earth Observation for Water Resources Management provides a series of practical guidelines that can be used by project leaders to decide whether remote sensing may be useful for the problem at hand and suitable data sources to consider if so. The book concludes with a review of the literature on reliability statistics of remote-sensed estimations.
