Operationalizing digital soil mapping for nationwide updating of the 1:50,000 soil map of the Netherlands

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 ...

Digital soil mapping for site-specific management of soils

Geoderma, 2019
Abstract 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 ...

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

Soil Surveys in Brazil and Perspectives in Soil Digital Mapping

Soil Horizons, 2015
In 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 ...

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 ...

Sampling for validation of digital soil maps

European Journal of Soil Science, 2011
The increase in digital soil mapping around the world means that appropriate and efficient sampling strategies are needed for validation. Data used for calibrating a digital soil mapping model typically are non‐random samples. In such a case we recommend collection of additional independent data and validation of the soil map by a design‐based sampling

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 ...

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.

Digital Mapping of Soil Classes and Continuous Soil Properties

2018
Soil is often described as mantling the land more or less continuously with the exception being where there is bare rock and ice (Webster and Oliver 2006). Our understanding of soil variation in any region is usually based on only a small number of observations made in the field.
