Efficiency Comparison of Conventional and Digital Soil Mapping for Updating Soil Maps

Soil Science Society of America Journal, 2012
This study compared the efficiency of geostatistical digital soil mapping (DSM) with conventional soil mapping (CSM) for updating soil class and property maps of a cultivated peatland in the Netherlands. For digital soil class mapping, the generalized linear geostatistical model was used.

Digital soil mapping of soil burn severity

Soil Science Society of America Journal
Abstract 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 Mapping of Soil Carbon

2013
Abstract 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 ...

Digital soil mapping across the globe

Geoderma Regional, 2017
Abstract Digital soil mapping has largely expanded across the globe since the early 2000s. Numerous national, continental and global digital soil mapping products have been produced. In this paper, we review some major developments and highlight areas where progress is needed, including refinements in uncertainty assessments and increasing soil data ...

Updating a Physiography-Based Soil Map Using Digital Soil Mapping Techniques

2016
Research work carried out in Entre-Rios province (Argentina) for mixed land use planning and management in relation to suitable soil conditions required high-resolution soil information at farm level. Basic information was provided by a 1:20,000 scale soil map made using physiographic analysis with intensive aerial photo-interpretation of soil ...

Pedology and digital soil mapping (DSM)

European Journal of Soil Science, 2019
Pedology focuses on understanding soil genesis in the field and includes soil classification and mapping. Digital soil mapping (DSM) has evolved from traditional soil classification and mapping to the creation and population of spatial soil information systems by using field and laboratory observations coupled ...

Digital Soil Mapping: Implementation and Assessment

2020
As a science grows, its underlying concepts change, although the words remain the same. The following chapter will be devoted to implementation and assessment of DSM. We discuss the various methods that have been, or could be, used for fitting relationships between soil properties or classes and soil-forming factors.

Using Proximal Soil Sensors for Digital Soil Mapping

2010
There is a great need for soil data to be used in natural resource assessment and management, e.g. for environmental modelling and digital soil mapping (DSM) to better understand soil processes and reduce risks in decision making. Conventional soil survey cannot efficiently provide these data because the techniques are time consuming and expensive ...
