Digital Mapping of Soil Organic Carbon Based on Machine Learning and Regression Kriging

Sensors, 2022
In the last two decades, machine learning (ML) methods have been widely used in digital soil mapping (DSM), but the regression kriging (RK) model which combines the advantages of the ML and kriging methods has rarely been used in DSM. In addition, due to

Principles, structure and taxonomic units in the russian and international (WRB) systems of soil classification

Бюллетень Почвенного института им. В.В. Докучаева, 2015
Two classification systems under comparison differ in objects, terminology, hierarchical levels, and approaches to identify soils. However, they have some common features: both systems are oriented to soil properties and apply the pedogenetic concepts ...

Impact of Land use on soil quality: Insights from the forest-savannah transition zone of Ghana

Heliyon
Land use changes have a profound impact on soil fertility and agricultural production systems in the Forest-Savannah Transition Zone (FSTZ) of Ghana. Soil erosion and shortened fallow periods exacerbate soil fertility loss, further degrading soil quality.
