As with the highly popular original, this new edition of Soil Sampling, Preparation, and Analysis provides students with an exceptionally clear description of the sampling and analysis methods most commonly used in modern soil laboratories around the world. What sets it apart as the first choice of professors is the grounding it offers in fundamental principles, professional protocols, and specific procedures. What makes it especially popular with students is that it spares them from having to tote large volumes for the sake of a page or two.

Fully revised to introduce the latest advances, the text is lucidly illustrated with original results garnered from years of hands-on experiments conducted by the author and his students.

In response to requests from active users of the first edition, these new features have been added:

Three new chapters on soil and plant test methods

A focus on testing and analysis limited to edaphology, as opposed to edaphology and pedology as a whole in the ecosystem

Information and insight reflecting the author's expertise on electron microscopy and nuclear magnetic resonance

Extensive revisions and expansion to include recent advances and shifting interests in the field

Soil Sampling, Preparation, and Analysis is divided into three sections: the first covers principles of soil sampling, sources of errors, and variability of results; the second explains common procedures for extraction and analysis in soil plant testing; and the last covers instrumentation.

While Professor Tan designed and further honed the book to serve the practical needs of students, with this volume he also provides them with an essential reference that will continue to serve them throughout their training and into their careers.


A study of environmental soil science. This second edition presents new material on: abiotic, biological and biochemical weathering of minerals in soils; microbial compounds such as enzymes, hormones, mucigel, and extracellular polysaccharides; electric double layer theory; desertification and soil degradation as well as natural processes of ageing; low-input sustainable agriculture; schemes for cultivating crops in outer space; and more.

Highlighting the vast differences in tropical climate, from hot and humid to cool and arctic, Soils in the Humid Tropics and Monsoon Region of Indonesia explores the climate, soil zones, and altitudinal variation in soil formation. The author explores the changes in geomorphology, especially in climate and vegetation above sea level, that ha

The field of humic matter research has undergone drastic changes in concepts and principles since the first edition of Humic Matter in Soil and the Environment: Principles and Controversies was published more than a decade ago. Still the only book of its kind specifically addressing humic acid principles and controversies, the Second Edition presen

Incorporating fundamental principles as well as up-to-date applications in soil formation, this work emphasizes the equal importance of organic and inorganic soil constituents by delineating the role of complex carbohydrates, amino acids, proteins, lipids, nucleic acids, lignins, enzymes, and humic acids in soil reactions. This edition features coverage of the relation of pe-pH with the biochemical cycle, soil air quality and soil humidity, thermodynamics in cation exchange and its connection with the quantity/intensity ratio, and more.
