Page Summary
-
iSDAsoil provides predicted mean and standard deviation for various soil properties at depths of 0-20 cm and 20-50 cm across Africa.
-
Soil properties available include bulk density, clay, sand, silt, stone, organic carbon, total carbon, total nitrogen, pH, extractable elements (calcium, iron, magnesium, phosphorus, potassium, sulfur, zinc, aluminium), depth to bedrock, effective cation exchange capacity, and USDA texture class.
-
Pixel values for some properties require back-transformation using specified formulas.
-
Model accuracy is low in areas of dense jungle, which may result in visible artifacts like banding.
-
The data was generated by Innovative Solutions for Decision Agriculture Ltd.(iSDA) at a 30m pixel size using machine learning.
