Classe de texture USDA à des profondeurs de sol de 0 à 20 cm et de 20 à 50 cm.
Dans les zones de jungle dense (généralement en Afrique centrale), la précision du modèle est faible. Des artefacts tels que des bandes (rayures) peuvent donc apparaître.
Les prédictions des propriétés du sol ont été effectuées par Innovative Solutions for Decision Agriculture Ltd. (iSDA) à une taille de pixel de 30 mètres à l'aide du machine learning associé à des données de télédétection et d'un ensemble d'entraînement de plus de 100 000 échantillons de sol analysés.
