could be translated to at least 2 or 3 soil types in the international (target) system. In this computational notebook we show how to generate a global map of soil types, how to access thepredictions we produced(GB of data), and how to further learn about your own soil. These ...
The major objectives of this study were: (i) to spatially predict and map the FAO soil groups in Denmark using decision tree modelling; (ii) to identify the potential environmental drivers for soil type variability in Denmark; and (iii) to evaluate the model prediction performance using the ...
Digital Soil Mapping (DSM) is the computer-assisted production of digital maps of soil type and soil properties. It typically implies use of mathematical and statistical models that combine information from soil observations with information contained in correlated environmental variables and remote sensing...
11). Colours correspond to the type of interactions (soil properties × vegetation, soil properties × climate or vegetation × climate). c–i Variable importance of the first five two-way interaction terms in the interaction models for bacterial and fungal functional groups for (c) ...
LUCAS in latitude 58-59 N, mountain, heath & bog land cover, and histosols, which we speculate may result from the high SOC concentrations predicted in the Hebrides and much lower concentrations predicted elsewhere at this latitude band, land cover type and soil group (see LUCAS map in Fig...
In addition, one single model is used to generate SOC predictions at desired depths, as the soil is treated as a whole 3D structure. We also provided an uncertainty map of SOC distribution for 0–100 cm depth using the QRF method. Using the difference between upper and lower quantiles, ...

The objectives of this study are to produce a physiographic soil map with correlated attributes to be a base for extra modifiers within the land information system. This integrated data will serve the purposes of land use planning, precision farming practices and to be applied in other areas usin...
Variability of soil within three areas of the Denchworth map unit in southern England Has been investigated by describing and analysing samples from thirty profiles located at the intersects of a randomly oriented grid. The Denchworth series has been mapped over several stratigraphically different clay...
7). On average, SOC exceeded 20 g kg− 1 in soils of the cold and temperate zones, reached up to 40 g SOC kg− 1 when MAP was between 500 and 750 mm, and up to 110 g SOC kg− 1 when MAP was between 800 and 1000 mm. In the tropics, SOC was below 5 g kg− 1 ...
