Short summary
We studied soil degradation in smallholder grazing areas in Western Kenya, comparing remote sensing (RS) classifications with soil data from 90 sites. Carbon and nutrient measures aligned somewhat with RS, but fast-changing variables did not. Results suggest combining RS with microbial biomass C, soil P, % C, % N, and pH can improve detection of degraded soils and guide restoration efforts
