The Scheffer/Schachtschabel Lehrbuch der Bodenkunde (Textbook of Soil Science), the renowned standard textbook on soil science in German-speaking countries such as Germany, Austria and Switzerland, is now available in English for the first time.  The first edition of this highly cited book was published in 1937 under the title “ Agrikulturchemie, Teil A: Boden ” (Agricultural Chemistry, Part A: Soil).  Based on the 16 th   German edition which was written by a team of leading soil scientists (all renowned professors of soil science), the 2016 English edition was published by Springer Verlag, so it is available globally. I really applaud this development since I have always admired and used this book since the time I was a doctoral student in Stuttgart-Hohenheim many years ago and until now as a professor of soil science at Visayas State University. I remember I read the 10 th German edition several times, from cover to cover, in preparation for my comprehensive examina...

A new book titled " Friedrich Albert Fallou und the Begruendung der Bodenkunde " (Friedrich Albert Fallou and the Founding of Soil Science) has been published in 2013 as volume 33 (Heft 33) of the " Waldheimer Heimatblaetter ", a monograph series published by Waldheim, a town in Saxony, Germany. Friedrich Albert Fallou & the Founding of Soil Science F.A. Fallou (1794-1877) has been considered by several authors as the Father of Soil Science. This was the subject of an article I posted earlier on this blog . Unfortunately, this distinction has been wrongly attributed to the Russian V.V. Dokuchaev. For this reason, the prominent Russian historian Jarilow wrote in 1904 that "Fallou is one of humanity's forgotten best sons". The book  provides clear and strong evidence that Fallou founded the scientific study of soil. It was authored by two retired prominent professors, Prof. Dr. Heiner Kaden (Chemistry, Technical University Freiberg) and Prof. Dr. Han...

Dr. Nicolas L. Galvez (1903-1991) laid down the groundwork for the different fields of soil science in the Philippines and he trained many Filipino soil scientists as a professor at the University of the Philippines College of Agriculture (UPCA) for 42 years. He was the head of the Soils Department at UPCA from 1948 to 1961, a difficult but crucial post-war period that had long-term impact on the development of soil science as an academic field in the country. Upon his retirement in 1970, Dr. N.L. Galvez was honored by being appointed as a University of the Philippines Los Banos (UPLB) Emeritus Professor.  Dr. N.L. Galvez (Source: SAED, UPLB-CA) Dr. N.L. Galvez was an internationally recognized scientist having published numerous relevant scientific papers on soil chemistry, soil mineralogy, and other aspects of soil science. For his pioneering and great contributions to the development of soil science in the Philippines, Dr. Galvez is widely considered, and deserves to be called, ...

Students of soil science are taught that to determine the amount of soil organic matter, soil organic carbon is measured usually by wet oxidation using potassium dichromate (called Walkley-Black method) or in well-equipped laboratories, using CN analyser and then multiplied by a conversion factor of 1.72 or 1.724. Most textbooks and laboratory manuals do not explain how this factor was obtained, so students generally accept the value without any question just like they do with other constants used in natural sciences.  Origin of the conversion factor The conversion factor has a very long history and has practically survived the test of time and modern analytical methods. It is about 150 years old. It was based on studies in the 1820s by the famous agricultural chemist, Carl Sprengel of Goettingen University, that organic matter contains 58 percent carbon. But it was another leading agricultural chemistry pioneer, Emil Wolff from Hohenheim, who introduced the value of 1.724 in 1864....

The catena concept in soil science comes from the Latin word “catena” which means chain. So it is a chain of soils linked by topography. It also refers to a sequence of soils in different positions in the landscape. It was introduced to the scientific literature by Geoffrey Milne (1898-1942) in a paper entitled “Some suggested units of classification and mapping particularly for East African soils” published in Soil Research-Bodenkundliche Forschung, Supplement to the Proceedings of the International Union of Soil Science Vol. IV No. 3 (1935), pp: 183-198. He noted “the regular repetition of a certain sequence of soil profiles in association with topography” in East Africa which was also observed earlier (in 1911 and 1912) by the German Peter Vageler. Milne wrote that "a distinctive word is needed in referring to this phenomenon" hence, he proposed the word catena. Ernst Schlichting (1923-1988) who was professor at the University of Hohenheim in Stuttgart pioneered the appro...

The Hohenheimer Bodenkundliche Hefte (ISSN 0942-0754) or Hohenheim Soil Science Book Series will be 20 years old in 2012. Since the release in 1992 of Volume 1 with the title “Stickstoff-Dynamik in Catenen einer erosionsgepraegten Loesslandschaft by G. Lorenz” (Nitrogen dynamics in catenas of an erosion-affected loess landscape), it has already published a hundred volumes of original and relevant soil research. Volume 100 which came out last year (2011), was authored by Shabnam Rathore and carried the title “Assessment of biomass production potential on salt affected land: a soil and terrain database case study (SASOTER) in Badin District, South of Pakistan.” Published by the renowned Institute of Soil Science and Land Evaluation of the University of Hohenheim in Stuttgart, Germany, this book series publishes dissertations and habilitations carried out at the Institute. During its early years, it was edited by Prof. U. Babel (Soil Biology), Prof. W.R. Fischer (Soil Chemistry), Prof. K....

December 05 of every year is celebrated as World Soil Day by the global community of more than 60,000 soil scientists. According to the official IUSS website, World Soil Day is held on the said date since it is the birthday of H.M. King Bhumibol Adulyadej, The King of Thailand, who has officially sanctioned the event. As a tribute to the soil as a vital resource, I am posting below a poem written in 2007 by one of my former students at Visayas State University, Juvia P. Sueta. Juvy is now finishing her PhD at the Buesgen Institute, University of Goettingen, Germany. The Soil Beneath by Juvia P. Sueta The soil tells a fascinating story of enduring patience and great beauty. Out of the hardened rock, it changes into an interesting mass of sand, silt, and clay. Exposed to the rain, wind and sunshine, it grows to maturity. Time polished it, throughout all history. Out of its bosom, the flowers bloom and trees grow steadily. And in its face, the children play. Below it; scholars, artists,...

In American soil science, pedology (pedo is Greek for ground or soil) has recently been made as a subdiscipline that deals with soil morphology, genesis and classification. In other parts of the world, however, particularly in non-English speaking countries in Europe, Asia and Africa soil science has remained synonymous to pedology (Bech, 2006). Historically, pedology was the original term for the scientific study of the soil introduced by Fallou and it was only in 1924 during the planning for the first international congress that the term soil science was introduced as a synonym. This was in fact reflected in the paper that Glinka presented during the congress (Glinka, 1927). Until today many textbooks, scientific journals and academic departments dealing with soil science in non-English speaking countries bear the name pedology. In 2002, there was an internet debate among some members of the International Union of Soil Sciences (IUSS) about the term pedology. While many North America...

Below is my short article which appeared in the IUSS Bulletin 117 (Nov 2010) and 118 (June 2011) under the title "Favorite Soil Science Books." Soil science is a rapidly growing ecological earth science. Consequently, the number of books on the subject has greatly increased in the last two decades. So to choose my top three soil science books, I thought of this criterion: the book must have been very useful to me when I was a student and it is still useful now in my research and teaching activities as a professor of soil science. The criterion automatically disqualifies some very good books that I used as a student but for various reasons I seldom or do not use them today as well as some outstanding soil science books published in recent years but were not yet available during my student days. My first choice is the Properties and Management of Soils in the Tropics by Pedro A. Sanchez published in 1976 by John Wiley and Sons. It discusses in a simple but in-depth manner t...

History is one of the most complicated and subjective academic fields since it is greatly influenced by the knowledge, experience, interest, and personal taste of the authors who reconstruct the history of a given event or human endeavour. It also depends on the availability and accuracy of historical records as well as on the degree of detail of the historical account. The renowned historian Norman Davies author of the book "Europe: A History" (Pimlico, London, 1365pp) wrote that "history can be written at any magnification. One can write the history of the universe on a single page, or the life-cycle of a mayfly in forty volumes." Thus, it is not unusual to read many different versions or revisions of the historical account of a past event. The history of soil science is no exception. Some aspects of it are still controversial such as the one about its founder. Although the Russian geographer Vasilii Vasilevich Dokuchaev (1846-1903) is widely considered as the fou...

First published June 2009. Revised November 2016. Philippine soil science owes its early development to the Americans. The first soil survey was conducted by C. W. Dorsey an American soil surveyor in 1903. In 1921 a Division of Soil and Fertilizer was created under the Bureau of Science which in 1934 was renamed as Division of Soil Survey. In 1951, the Philippine Congress enacted Republic Act No. 622 organizing the Bureau of Soil Conservation with Dr. M. M. Alicante as its first director (BSWM, 2008). Teaching of soil science to students of agricultural science started as early as the 1920s at the University of the Philippines College of Agriculture (UPCA). R. L. Pendleton an American from California was one of the pioneer soil science instructors who taught from 1923 to 1935. Dr. Pendleton was also an outstanding researcher as reflected by the about 50 scientific papers he published (Pendleton, 1942; Carter, 1958). Until about the 1960s, much of the work of soil scientists in the Bur...

One of the most influential books on soil science in the 20 th century was the Handbuch der Bodenlehre (Handbook of Soil Science), a 10-volume book edited by Professor Edwin Blanck of the University of Göttingen, Germany, and published by Verlag von Julius Springer, Berlin, from 1928-32 (see photo). The book presented the state of the art in soil science until the late 1920s. According to the prominent soil scientist Professor Dan Yaalon of Hebrew University , modern soil research took off at an accelerated rate as a result of the publication of this monumental book by Blanck (Yaalon and Berkowicz, 1997). The contents of the different volumes are as follows: Volume 1- The Natural Science Principles of the Origin of Soils; Volume 2- The Climatic Principles of the Formation and Weathering of Soils; Volume 3- The Distribution of Soil types on the Earth’s Surface, Regional and Zonal Soil Science; Volume 4- Non-climatic Soil Formation, the Soil Forms in Germany and Fossils Weathering; V...
