Pál Stefanovits (1920-2016)

The Hungarian Soil Science Society and the IUSS Secretariat were sad to learn that our distinguished soil scientist Pál Stefanovits died on August 4th, 2016 at the age of 95. The major scientific fields of professor Stefanovits span from soil minerals to soil classification and mapping. The development of the Hungarian soil classification system and his classic soil text books were the foundation of a strong soil science school in Hungary. His publications, participation in international meetings and soil mapping projects brought him international recognition. The death of Pál Stefanovits, honorary president of the Hungarian Soil Science Society, member of the Hungarian, the Ukrainian, the German and the Austrian Academy of Sciences, is a great loss for the international soil science community. His legacy will be summarised in the next IUSS Bulletin.

ISRIC World Soil Museum can now be visited virtually

The World Soil Museum of ISRIC – World Soil Information in Wageningen can now be visited online. The museum has a collection of reference soil profiles from around the world. These 3D profiles, or monoliths, are used to explain main soil forming factors and to show the importance of the soil for ensuring food security, mitigating climate change, or in terms of their cultural value. The museum, the collection, including the objects in the collection storage – normally off limits to visitors – can now be visited online. You can explore the museum as part of an online tour and search for specific data and information on each soil profile. Further, you can also view profiles from the storeroom which houses the majority of the collection, and obtain a complete overview of the soil profiles by country or soil type. This means you can put together your own exhibition for your studies or as a work project. The virtual tour is available in English. The scope of the virtual tour will be gradually extended.

Spatial and temporal variability of soil water content

The topsoil water content plays a key role in partitioning energy and water fluxes at the land surface. Knowledge about its spatial and temporal variability is crucial for improving climate and hydrology modelling. In the June 2016 issue of Vadose Zone Journal, researchers studied the spatial heterogeneity of topsoil water content, which is expressed as the relationship of the spatial standard deviation of the topsoil soil moisture to the spatial mean soil moisture. Past studies have shown that sq first increases during drying out, reaches maximum value at some critical spatial mean soil moisture and then decreases thereafter. However, the drying out and rewetting processes sequentially alternate each other in time, and this relationship demonstrates hysteresis.

The 7 biggest problems facing science, according to 270 scientists

Science is in big trouble. Or so we’re told. In the past several years, many scientists have become afflicted with a serious case of doubt — doubt in the very institution of science. As reporters covering medicine, psychology, climate change, and other areas of research, we wanted to understand this epidemic of doubt. So we sent scientists a survey asking this simple question: If you could change one thing about how science works today, what would it be and why?

Soil microbes burp carbon dioxide after drought-breaking rain

An unpredictable source of carbon emissions in areas of sporadic rainfall is the carbon dioxide released from soil when rain falls after drought. The emissions come from soil microbes, and as Catherine Osborne explains, these critters are very difficult to study. But recent advances in DNA sequencing technology have made things easier. In her work at the University of California Berkeley, Catherine investigated soil microbes.

The definition of soil since the early 1800s

Soil scientists and the definition of soil have changed over time. This paper reviews how the definition of the soil has changed since the early 1800s by selecting and listing 81 definitions given in a wide range of soil science books, handbooks, glossaries and dictionaries. Initial definitions of the soil were based on developments in agricultural chemistry or geology. The soil was seen as a production factor (medium) for agriculture that needed to be understood before it could be improved, or the soil was defined as disintegrated rocks mixed with organic matter. Definitions were rudimentary reflecting the overall level of understanding. This review ends with a proposal for a scientific definition of soil, and a definition for lay persons and the general public.

Sustainable soil management key to Africa's food security

The Status of the World’s Soil Resources report has established that 40 per cent of Africa’s soils are severely degraded. A recent report published in Down To Earth points out that desertification has turned out to be a big challenge for Africa, seriously undermining its efforts in sustainable soil management. The continent suffers from soil erosion and low soil fertility which pose a threat to food production. By 2050, Africa will witness an enormous growth in population. According to the Food and Agriculture Organization (FAO) of the United Nations, more than a quarter of sub-Saharan Africa’s people are undernourished. Crop production will need to increase by 260 per cent by 2050 to feed the continent’s population. Better land management practice is one of the ways to fight climate change and increase resilience of farming systems in the continent.

Soil Phosphorus

Edited by Rattan Lal, B. A. Stewart; August 2016 by CRC Press. 339 pages, 15 colour illus., 47 B/W illustrations, ISBN 9781482257847, price hardback: £89.00. Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus.
