Soil functioning indicators decline with land-use intensification in the Peruvian Amazon: evidence from Ucayali

Introduction Rapid land-use change in the Peruvian Amazon threatens soil processes that sustain productivity and ecosystem resilience. This study assessed soil functioning indicators along a land-use intensification gradient in Ucayali, Peru. Methods We evaluated physicochemical (texture fractions, pH, organic matter, cation-exchange capacity, carbon, and micronutrients) and biological indicators (cultivable microbial groups, microbial biomass carbon, respiration, and macrofauna) from 54 indepen
