Reconstructing Quaternary landscapes and hydrology from soil survey maps

, 2018
This study was done to investigate the pre-settlement condition of the southern Des Moines Lobe landscape, with particular interest in the hydrological function of depressional wetlands. Soil survey maps were used to identify the soil formation environment from soil properties observed today.

The Role of Digital Soil Mapping in Soil Survey and Agricultural Planning

International Journal of Plant & Soil Science
Digital Soil Mapping (DSM) is an essential tool for soil survey and agricultural planning. It involves creating and populating spatial soil information using field and laboratory observations, often referred to as "predictive soil mapping" or "pedometric mapping." DSM provides detailed information on various soil properties, including soil pH, soil ...

Adaptive sampling and reconnaissance surveys for geostatistical mapping of the soil

European Journal of Soil Science, 2005
Summary The effort required to survey a soil variable depends upon the acceptable uncertainty of estimates and the variogram of the variable. The variogram is unknown prior to sampling, so it must be inferred from a reconnaissance survey before an efficient survey can be designed.

A survey on inline soil pollution measurement and mapping technologies

Measurement
This paper reviews recent advancements in underground positioning and monitoring, particularly for soil pollution detection and mapping. Unlike conventional indoor and outdoor systems, underground environments pose unique challenges. Robotic platforms, including the Moon/Mars Underground Mole (MMUM) and bioinspired Mole-bot, utilize drills, augers, and

Land husbandry: an agro-ecological approach to land use and management Part 1: Considerations of landscape conditions

International Soil and Water Conservation Research, 2014
In this, the first of two papers, the roles of key features of any landscape in determining potentials for erosional losses of soil and water are considered from an agro-ecological viewpoint.

Digitization and mapping of national legacy soil data of Montenegro

Soil and Water Research, 2018
This paper describes the process of digitizing Montenegro's legacy soil data, and an initial attempt to use it for digital soil mapping (DSM) purposes. The handwritten legacy numerical records of physical and chemical properties for more than 10 000 soil

Mapping soil property classes over a large territory with multiple soilscapes by digital extrapolations of legacy detailed soil maps: A case study in Karnataka -South India

Geoderma
Using detailed soil maps to calibrate DSM models could be an alternative to point observations, as they would account for local soil patterns more accurately than the sparse sets of soil profiles classically used in broad-scale DSM applications. However,

Locally enhanced digital soil mapping in support of a bottom-up approach is more accurate than conventional soil mapping and top-down digital soil mapping

Geoderma
This study presents a regional digital soil mapping (DSM) product that used a locally enhanced method in support of a bottom-up approach to create spatial soil predictions that were more accurate than one of the most accurate and detailed conventional ...

Simulating water dynamics related to pedogenesis across space and time: Implications for four-dimensional digital soil mapping

Geoderma
Digital soil mapping (DSM) relies on machine-learning and geostatistics to represent soil property observations across space. DSM techniques are powerful but often empirical, being limited to the quality and density of point samples.
