Abstract
Highlights:
•How to predict and map soils within smallholder farms in fragile landscapes of Malawi?
•randomForest and sentinel imagery improves mapping of SOC and NPK farm level.
•SOC predicted by bare soil reflectance, N: vegetation, P: topography, K is indiscrete.
•Map reveal SOC & NPK stoichiometric thresholds at scale for small-farm management.
