GIS IN SOIL SURVEY AND SOIL MAPPING

open access: yesGeodesy and cartography, 2021
The main goal of this paper is to present a methodology for land evaluation by supporting decision-makers with reliable information for the land-use planning process. One of the focuses of this paper is given to the survey process and interpretation between soil survey, soil survey interpretation, and physical land evaluation.

Global maps of soil temperature [PDF]

open access: yesGlobal Change Biology, 2021
AbstractResearch in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here,

Harmonisation of a large-scale historical database with the actual Czech soil classification system

open access: yesSoil and Water Research, 2020
The possibility of the adequate use of data and maps from historical soil surveys depends, to a large measure, on their harmonisation. Legacy data originating from a large-scale national mapping campaign, "Systematic soil survey of agricultural soils in ...

Spatial aspects of applied Soil Science

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2020
The analysis of peculiarities of applied use of soil data has been carried out. It is shown that most of practical tasks require spatial information about soils and their properties. In this regard, a soil map is considered as a kind of interface between

Digital soil mapping from conventional field soil observations

open access: yesSoil and Water Research, 2013
We tested the performance of a formalized digital soil mapping (DSM) approach comprising fuzzy k-means (FKM) classification and regression-kriging to produce soil type maps from a fine-scale soil observation network in Rišňovce, Slovakia.

Advanced Backcross QTL Analysis of Fiber Strength and Fineness in a Cross between Gossypium hirsutum and G. mustelinum

open access: yesFrontiers in Plant Science, 2017
The molecular genetic basis of cotton fiber strength and fineness in crosses between Gossypium mustelinum and Gossypium hirsutum (Upland cotton) was dissected using 21 BC3F2 and 12 corresponding BC3F2:3 and BC3F2:4 families.

A Framework for Retrieving Soil Organic Matter by Coupling Multi-Temporal Remote Sensing Images and Variable Selection in the Sanjiang Plain, China

open access: yesRemote Sensing, 2023
Soil organic matter (SOM) is an important soil property for agricultural production. Rising grain demand has increased the intensity of cultivated land development in the Sanjiang Plain of China, and there is a strong demand for SOM monitoring in this ...

Refined Evaluation of Soil Quality Sustainability in the Main Grain-Producing Areas of Heilongjiang Province

open access: yesAgronomy, 2023
An evaluation of soil quality sustainability can support decision making for the sustainable use of land resources. However, certain current problems associated with these evaluations remain unaddressed, e.g., the evaluation indicators do not fully ...

Mapping soils in Ireland

open access: yes, 2014
peer-reviewed This project is jointly funded by Teagasc and EPA STRIVE funding. Harmonised soil data across Europe with a 1:250 000 geo-referenced soil database will allow for exchange of data across member states and the provide the information needed for reporting on issues re-lating to soil quality under a future Soil Framework Directive.

Errors in soil maps: The need for better on-site estimates and soil map predictions

open access: yesPLOS ONE, 2023
High-quality soil maps are urgently needed by diverse stakeholders, but errors in existing soil maps are often unknown, particularly in countries with limited soil surveys. To address this issue, we used field soil data to assess the accuracy of seven spatial soil databases (Digital Soil Map of the World, Namibian Soil and Terrain Digital Database ...
