Updating the national soil map of Nepal through digital soil mapping

Geoderma, 2021
Abstract 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 ...

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.

Soil Types, Soil Classification, and Mapping

2021
Nepal exhibits unique topographic features with great biodiversity variation within a short gradient. The variation, along with the gradient, is coupled with heterogeneous soil types. Entisols, Inceptisols, Alfisols, and Mollisols are commonly found soils in Tarai and the Middle Mountain physiographic regions.

Updating Conventional Soil Maps through Digital Soil Mapping

Soil Science Society of America Journal, 2011
Conventional 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.

Mapping soil, losing ground? Politics of soil mapping

2020
Kon Kam King and Céline Granjou document the evolution of soil mapping since the 1960s at the French National Institute of Research on Agriculture (INRA). They account for the shift from soil surveying initiatives to the rise of soil digital mapping projects, including monitoring, modeling, and predicting soil quantitative properties, such as carbon ...

Soil Research and Soil Mapping History

2013
In Pre-Hispanic time, the native ethnic groups living at the Mexican territory already had significant soil knowledge that included classification of soils and a developed system of soil management. Until now, the folk knowledge may provide valuable information for soil research.

Soil maps of Wisconsin

Geoderma, 2012
Legacy soil maps are an important input in digital soil mapping. This paper traces how reconnaissance soil maps in Wisconsin evolved between the 1880s and the present with some discussion on future directions. The first soil map in the USA was made in Wisconsin by the geologist T.C. Chamberlin in 1882.

Soil Research and Soil Mapping History

2020
The documented evidence shows that the soils of Sri Lanka were first studied according to crops grown as tea, coffee, cinnamon, rice, and forest soils as early as 1886. The first agricultural experiment in the world according to the factorial design was established in 1929 by Eden (Eden 1929) at St.
