iSDAsoil Extractable Potassium

Extractable potassium at soil depths of 0-20 cm and 20-50 cm, predicted mean and standard deviation. Pixel values must be back-transformed with `exp(x/10)-1`. In areas of dense jungle (generally over central Africa), model accuracy is low and therefore artifacts such as banding (striping) might be seen. Soil property predictions were made by [Innovative Solutions for Decision Agriculture Ltd. (iSDA)](https://isda-africa.com/) at 30 m pixel size using machine learning coupled with remote sensing
