Updating Conventional Soil Maps through Digital Soil Mapping
Soil Science Society of America Journal, 2011Conventional soil maps, as the major data source for information on the spatial variation of soil, are limited in terms of both the level of spatial detail and the accuracy of soil attributes. These soil maps, however, contain valuable knowledge on soil-environment relationships.

Updating the national soil map of Nepal through digital soil mapping
Geoderma, 2021Abstract While most legacy soil maps are available at coarse spatial detail with composite mapping units, high resolution and detailed soil maps are desired for various land resource applications. In time and resource constrained circumstances, the application of disaggregation methods and modelling approaches that capitalise on existing, less ...

Digital Mapping of Soil Carbon
2013Abstract There is a global demand for soil data and information for food security and global environmental management. There is also great interest in recognizing the soil system as a significant terrestrial sink of carbon. The reliable assessment of soil carbon (C) stocks is of key importance for soil conservation and in mitigation strategies for ...

Geoderma, 2015
Abstract This paper presents a pedometric approach to updating the Dutch 1:50,000 national soil map for the peatlands, and illustrates this approach for a 187,525 ha area in the northern peatlands. This is the first time that digital soil mapping replaces conventional soil mapping in a nationwide, government-funded soil survey program in the ...

Soil Surveys in Brazil and Perspectives in Soil Digital Mapping
Soil Horizons, 2015In analyzing the evolution of pedologic mapping perspectives in Brazil, it is noteworthy that they are based firmly on geology and focused on soil aptitude for agricultural use. Mapping detail was improved between the decades of 1950 and 1980. The mapping initially concentrated in the Northeast and Southeast regions, shifting its orientation in recent ...

Digital soil mapping of soil burn severity
Soil Science Society of America JournalAbstract Fire alters soil hydrologic properties leading to increased risk of catastrophic debris flows and post‐fire flooding. As a result, US federal agencies map soil burn severity (SBS) via direct soil observation and adjustment of rasters of burned area reflectance. We developed a unique application of digital

Digital soil mapping for site-specific management of soils
Geoderma, 2019Abstract Classification of fields into management zones based on variability of soil fertility parameters is under use in precision agriculture. The study was conducted in west Wollega zone of Ethiopia covering nearly 40 km2 of agricultural land, with the aim to explain variability of soils in the field, classify soils into mapping units and produce ...
