Abstract Soil organic carbon (SOC) quantification in a practical manner with reduced costs has become a necessity due to current agricultural demands. Studies have shown that remote sensing is important for SOC prediction, and its use has become crucial in agricultural management. In this study, a Linear Multiple Regression (LMR) model was constructed to predict SOC in a site in the region of Piracicaba, Sao Paulo, Brazil. We used the optical-satellite data of Landsat OLI sensor (bands 5 and 7),...
Abstract In this concluding paper, we summarize the main advances coming forward from the joint conference of the International Union of Soil Sciences (IUSS) Working Groups (WG) “Digital Soil mapping” (DSM) and “GlobalSoilMap”. We outline the increased availability of data and covariates. Large efforts to rescue legacy data and to put them in a harmonized format are ongoing in many parts of the world. New countries are joining the GlobalSoilMap initiative. During the same time, significant progr...

Abstract Mollisols are naturally fertile soils with a thick, friable, very dark coloured, organic rich, surface layer (mollic epipedon). Soils literature for 20 South Pacific island countries was examined for information on Mollisols; of these countries, 16 had confirmed Mollisols. Given the basic concept of Mollisols (continental grassland soils), this was an unexpected prevalence. Classifications using the USDA Soil Taxonomy identified 4 suborders, 10 great groups, and 33 subgroups of Mollisol...

Abstract The mineral soil Particle Size Distribution (PSD) is a fundamental and very useful soil characteristic widely used to support soil classification, soil management and soil processes modeling. An important limitation of PSD is the lack of standardization for granulometric fractions obtained from different soil classification systems, making difficult to compare and combine data. To overcome this drawback several attempts have been made to mathematically fit PSD data in order to allow soi...
Abstract Terrain attributes are used as auxiliary variables in spatial prediction of soil classes and properties, due to their important role in the pedogenetic process and the increasing availability of digital elevation models (DEMs) in different resolutions. This work analyzed the relationship between terrain attributes in different spatial resolutions for digital soil mapping in prediction models. We used three spatial resolutions from different DEMs: (1) LIDAR – 2 m; (2) ALOS PALSAR – 12.5 ...

Abstract Andisols, rich in minerals like allophane, imogolite and iron- (Fe) or aluminum- (Al) oxides have high phosphorus (P) sorption capacity and require annual P additions to ensure plant productivity. It is known that the use of composted poultry manure (PM) increases soil labile P and carbon concentration, although the mechanisms controlling P availability and soil organic carbon (SOC) sequestration are not fully understood. The aim of this study was to investigate the relationship between...

Abstract Soil-landscape studies using quantitative methods tackled as pedodiversity recently became popular in soil geography. The experience gained in their application to different territories and at different scales is not plentiful yet, and the regularities revealed are not always evident and unambiguous. The present study aimed to investigate the effect of mapping scale and the classification used for mapping on the pedodiversity indices and taxonomic distances between the soils reflected o...

Abstract The GlobalSoilMap initiative significantly inspired the (Digital, Optimized, Soil Related Maps and Information in Hungary) project, which was started intentionally for the renewal of the national spatial soil data infrastructure in Hungary. The main objectives of our work has been to broaden the possibilities, how demands on spatial soil related information could be satisfied in Hungary, how the gaps between the available and the expected could be filled with optimized digit...

Abstract Synthetic fertilizer-induced nitrous oxide (N2O) emissions contribute to climate change. Enhanced efficiency fertilizers (EEFs) may reduce soil N2O emissions compared to conventional fertilizers like urea-ammonium-nitrate (“UAN”) and urea by better matching fertilizer N supply with plant N demand. This study tested whether three liquid EEFs (a nitrification inhibitor, “NI”, a urease inhibitor, “UI”, and a urease and nitrification inhibitor, “UI + NI”) and polymer-coated urea (Environmen...

Abstract Can less than a hundred years of past settlement activities in former European settlements substantially increase the concentration of elements and result in the formation of African Dark Earth soil is a question not addressed. We performed multi–element analysis of Africa Dark Earth soil from a late 19th to mid–20th century CE former German–Togoland settlement, Ziavi–Galenkuito in the Volta Region, Ghana. Relatively neutral reaction and black color of soil mainly from charcoal inclusio...
