Agricultural productivity growth is vital for economic and food security outcomes which are threatened by climate change. In the present times, changing climate is a burning issue. Climate change may be limited to a specific region or may occur across the earth.
Методические указания по лабораторным работам по курсу «Методы исследования вещественного состава природных объектов» предназначены для студентов и магистрантов, обучающихся по специальностям 020804 «Геоэкология».
Advances in nanotechnology over the past decade have made scanning electron microscopy (SEM) an indispensable and powerful tool for analyzing and constructing new nanomaterials. Development of nanomaterials requires advanced techniques and skills to attain higher quality images, understand nanostructures, and improve synthesis strategies.
Several instructors have contributed to the evolution of this laboratory manual over the years. Contributors include, alphabetically, Maurice G. Cook, Emeritus Professor of Soil Science, North Carolina State University; David A. Crouse, Associate Professor of Soil Science, North Carolina State University; Larry D. King, Emeritus Professor of Soil Science, North Carolina State University; H. Joseph Kleiss, Emeritus Professor of Soil Science, North Carolina State University; Colby J. Moorberg, Assistant Professor of Soil Science, Kansas State University; Lloyd Stone, Emeritus Professor of Agronomy, Kansas State University; and James A. Thompson, Professor of Soil Science, West Virginia University. Editorial support was provided by Nora Ransom. Contributions were also made by countless graduate teaching assistants over the development of the manual. Funding was provided by the Kansas State University Open/Alternative Textbook Initiative. This is contribution no. 18-128-B of the Kansas Agricultural Experiment Station <...>
Soil can exist as a naturally occurring material in its undisturbed state, or as a compacted material. Geotechnical engineering involves the understanding and prediction of the behavior of soil. Like other construction materials, soil possesses mechanical properties related to strength, compressibility, and permeability. It is important to quantify these properties to predict how soil will behave under field loading for the safe design of soil structures (e.g. embankments, dams, waste containment liners, highway base courses, etc.), as well as other structures that will overly the soil. Quantification of the mechanical properties of soil is performed in the laboratory using standardized laboratory tests. <...>
