General News

Georges PÉDRO (1929-2018) – French Soil Science has lost one of its most prestigious members

Georges Pédro died on January 31st 2019. He was born on June 26th 1929. He had just published his last scientific study Surface Cover of the Earth’s Continental Areas (ed. AFES, 2018).

Georges Pédro is internationally renowned for his work on clay minerology and geochemical weathering processes. He was a Research Director at the INRA (France’s national institute for agronomic research) and played a vital role in France in the field of Pedology. Amongst others, he was president of the Orstom-IRD’s “Commission scientifique d’Hydrologie et Pédologie” (1984) (Scientific Commission for Hydrology and Pedology) and supervised and co-supervised numerous Orstom PhDs. It was his own exceptional thesis on experimental pedology that made him famous throughout the world: he experimentally modelled the principal global processes of soil weathering in the laboratory.

He was a remarkable teacher (1965-1995) and numerous soil scientists attended his DEA lessons in Pedology and continued on to PhD with him. Georges Pédro was a member of both the Academy of Science and the Academy of Agriculture. He received the CNRS (France’s National Research Centre) silver medal in 1980 and was Officer of the French Legion of Honour. He was not only an exceptional scientist but also a great humanist, historian and a highly cultured and sensitive man. He took time for people. Many of us, his colleagues, feel that we have lost a great friend.

How are microplastics changing agricultural crops?

Invisible but pervasive, microplastics are washed into oceans and blown through the air. Now, scientists have uncovered that microplastics change agricultural crop growth. Agricultural soils could actually hold more microplastic than ocean basins. A new study explores the impact of microplastics on terrestrial systems, specifically agriculture. The researchers were interested in changes in the soil, microbes and plants exposed to microplastics. Pervasive microplastic contamination in soil may have consequences for plant performance, and thus for agroecosystems and terrestrial biodiversity.

Pesticide sorption properties plays a role in leaching even in frozen soils

Studies indicate that solute sorption properties are less important when preferential flow is the dominating transport pathway. There is evidence that pesticides leach through partially frozen soil during winter and early spring and that preferential flow through macropores may be the cause of this. The effect of freezing on the transport of pesticides with different sorption properties has not been investigated before. In the current issue of the Vadose Zone Journal, researchers report on a study where the effect of freezing on the transport of pesticides with a range of soil sorption coefficients was investigated.

Stop soil erosion now or face starvation soon, scientists warn

The world’s food production is in jeopardy because the fertile layer of soil that people depend on to plant crops is being eroded by human activities, scientists said recently. Climate change is likely to make it worse even as demand from a grown population is soaring, they said. Soil erosion happens naturally, but intensive agriculture, deforestation, mining and urban sprawl accelerate it and can reduce crop yields by up to 50%, according to the United Nations’ Food and Agriculture Organization (FAO).

WETSCAPES Conference – Understanding the ecology of restored fen peatlands for protection and sustainable use

10-13 September 2019, Rostock, Germany. Peatlands cover only 3 % of the land surface worldwide but with some 450 gigatonnes of carbon they contain substantially more than the carbon stock in the entire forest biomass of the world. Thus, peatlands are the most effective terrestrial carbon stock on our globe. A mosaic of paludiculturally used peatlands with peatlands restored primarily for nature conservation purposes is the future multifunctional and sustainable peatland landscape – the vision of ‘WETSCAPES’. In WETSCAPES, in contrast to past land use approaches, the water is kept in the landscape, thus facilitating carbon storage, nutrient retention, climate regulation, and habitat function.

New publications

Anthropogenic Soils in Japan

Edited by Makiko Watanabe and Masayuki Kawahigashi. Published in the Part of the International Perspectives in Geography book series (IPG) by Springer in June 2019, Print ISBN 978-981-13-1752-1, Online ISBN 978-981-13-1753-8, price e-book: EUR 101.14.

This book enhances the discussion of anthropized soils with photographs of soil profiles and provides general information about soils in Japan, using data on their physical and chemical properties. Soils targeted in this book have wide spectra in anthropized influences from lesser effects such as agricultural improvements to drastic changes caused by infrastructure construction. These include soils sealed by technic hard materials, on ski slopes, on river embankments and coastal berms, in historical urban parks, on man-made islands in Tokyo Bay, in reclaimed lands, in greenhouse fields, and those filling in swamplands.

The book includes information with new data produced by active researchers from many institutes and universities as it refers to soils altered by human activities and thus is informative to specialists in various disciplines related to soils. It is also valuable to students for viewing soils in cities, infrastructure construction areas, and other affected locations. Evaluation and understanding of soils now has become essential for researchers in a range of fields and for policy makers in agriculture as well as urban planning, civil engineering, and disaster sciences. This work serves as an impetus for launching further study of soils and environments.

Simple Methods to Study Pedology and Edaphology of Indian Tropical Soils

By D. K. Pal. Published by Springer in June 2019. Print ISBN 978-3-319-89598-7, Online ISBN 978-3-319-89599-4; price e-book: EUR 91.62.

This book discusses how research efforts have established an organic link between pedology and edaphology of five pedogenetically important soil orders as Alfisols, Mollisols, Ultisols, Vertisols and Inceptisols of tropical Indian environments. The book highlights how this new knowledge was gained when research efforts were complemented by high resolution mineralogical, micro morphological and age-control tools. This advancement in basic and fundamental knowledge on Indian tropical soils makes it possible to develop several index soil properties as simple methods to study their pedology and edaphology.

More than one-third of the world’s soils are tropical soils. Thus the recent advances in developing simple and ingenuous methods to study pedology and edaphology of Indian tropical soils may also be adopted by both graduate students and young soil researchers to aid in the development of a national soil information system to enhance crop productivity and maintain soil health in the 21st century.

Soil Clays – Linking Geology, Biology, Agriculture, and the Environment, 1st Edition

By G. Jock Churchman, Bruce Velde, CRC Press, June 28, 2019, 258 pages, 27 Color Illus., 70 B/W Illus., Hardback: ISBN 9781498770057, Price GBP 130,00.

This book aims to help improve predictions of important properties of soils through a modern understanding of their highly reactive clay minerals as they are formed and occur in soils worldwide. It examines how clays occur in soils and the role of soil clays in disparate applications including plant nutrition, soil structure, and water-holding capacity, soil quality, soil shrinkage and swelling, carbon sequestration, pollution control and remediation, medicine, forensic investigation, and deciphering human and environmental histories.

To know soil clays is to enable their use toward achieving improvements in the management of soils for enhancing their performance in one or more of their three main functions of enabling plant growth, regulating water flow to plants, and buffering environmental changes. This book provides an easily-read and extensively-illustrated description of the nature, formation, identification, occurrence and associations, measurement, reactivities, and applications of clays in soils.
