Book excerpt: Excerpt from Equipment and Methods for Measurements of Soil Temperature The bimetal dial thermometersfi/ have a coil-within-coil structure about 1 inches long located in the end of a hollow stem. Changes in temperature cause a rotary action of the bimetal helix; this turns a shaft on which a pointer is mounted. The instruments used in this study employed three indicators. One indicated the current temperature, a second the maximum temperature, and a third the minimum temperature. The thermometers can be purchased with different stem lengths for different soil depths. Van Bavel and Forrest (5) concluded that these thermometers were accurate to less than 1° F., were easy to read, and could withstand normal field exposure.

This book was released on 2018-02-15 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from An Evaluation of Dial Thermometers for Measuring Soil Temperature The thermistor used is designated by the manufacturer as model No. 7a disc type thermistor and is the same unit used in the Colman fiber glass soil-moisture element. It is a pellet of metal oxide, silver coated on its opposing sides, inches in diameter and inches thick. The manufacturer's rated resistance is ohms, plus or minus 10 percent at 25 degrees centigrade The resistance of the pellet is sensitive to changes in temperature. Consequently, it can be used to determine-temperature. Each of the two types of thermometers was installed, in duplicate, at h and 8 inch depths in Cecil clay loam soil, covered with a Bermuda grass sod. They were installed in a rectangular block such that there were four of one type in line, spaced about one foot apart, with the first and third thermometer being at the h-inch depth and the second and fourthat the 8 inch depth. This pattern was repeated for the second type with the line of thermometers placed about one foot from the first type and parallel to them. This installation resulted in the two types and depths being equidistant from each other. The dial type thermometers were installed by forcing the stem into the ground to the desired depth. Soil temperatures were read directly in degrees Fahrenheit from the dial scale without disturb ing the thermometers. A point 1 inch from the bottom of the stem was taken as the reference for depth. The 8 inch thermometer was therefore sunken into the surface by'l inch. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Soil Moisture Measurement Classic Reprint written by Howard W. Lull and published by Forgotten Books. This book was released on 2018-03-18 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soil-Moisture Measurement As has been noted, the gravimetric method is the only commonly used direct means of measuring soil moisture. Simply, it involves taking a soil sample, weighing it, oven-drying it, reweighing, and expressing the original moisture content in percent of oven-dry weight of soil. The first step, securing the sample, is the most troublesome, the degree of difficulty depending on the condition of the soil. Sampling conditions are ideal when soil is just moist enough for easy ingress and egress of the sampling instrument, and where stones, roots, and organic matter are not a problem. Such conditions are seldom encountered. With free water in the soil, moisture can never be sampled accurately: water will drip off as the sample is removed from the ground or compaction may squeeze it out. Rapid sampling is essential to prevent undue losses. Stickiness, often a problem in wet soils, can be alleviated by keeping instruments clean. Where a wet layer overlies a dry one, samples taken from the drier levels may be contaminated. After the upper soil is wetted by a summer rain, for instance, removal of a sample may permit water to run down the hole toward drier soil. The same problem is en countered when samples are taken below a perched water table. Wet instruments add to contamination and should be dried between samplings. When the soil is dry and hard, the principal problem in fine textured soils is to get the sampling instrument in and out again. In coarse-textured soils particularly, samples may slide out of the in strument as it is withdrawn from the soil. Fortunately, after the soil dries in summer, its moisture content may fluctuate so little that frequent sampling may be unnecessary.

Download or read book Treatise on Geomorphology written by and published by Academic Press. This book was released on 2013-02-27 with total page 6392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!

Book excerpt: Comprehensive Sampling and Sample Preparation is a complete treatment of the theory and methodology of sampling in all physical phases and the theory of sample preparation for all major extraction techniques. It is the perfect starting point for researchers and students to design and implement their experiments and support those experiments with quality-reviewed background information. In its four volumes, fundamentals of sampling and sample preparation are reinforced through broad and detailed sections dealing with Biological and Medical, Environmental and Forensic, and Food and Beverage applications. The contributions are organized to reflect the way in which analytical chemists approach a problem. It is intended for a broad audience of analytical chemists, both educators and practitioners of the art and can assist in the preparation of courses as well in the selection of sampling and sample preparation techniques to address the challenges at hand. Above all, it is designed to be helpful in learning more about these topics, as well as to encourage an interest in sampling and sample preparation by outlining the present practice of the technology and by indicating research opportunities. Sampling and Sample preparation is a large and well-defined field in Analytical Chemistry, relevant for many application areas such as medicine, environmental science, biochemistry, pharmacology, geology, and food science. This work covers all these aspects and will be extremely useful to researchers and students, who can use it as a starting point to design and implement their experiments and for quality-reviewed background information There are limited resources that Educators can use to effectively teach the fundamental aspects of modern sample preparation technology. Comprehensive Sampling and Sample Preparation addresses this need, but focuses on the common principles of new developments in extraction technologies rather than the differences between techniques thus facilitating a more thorough understanding Provides a complete overview of the field. Not only will help to save time, it will also help to make correct assessments and avoid costly mistakes in sampling in the process Sample and sample preparation are integral parts of the analytical process but are often less considered and sometimes even completely disregarded in the available literature. To fill this gap, leading scientists have contributed 130 chapters, organized in 4 volumes, covering all modern aspects of sampling and liquid, solid phase and membrane extractions, as well as the challenges associated with different types of matrices in relevant application areas
