Our project conducted multi-year cropping system experiments in two sub-watersheds in Ecuador: a pasture-potato system in the Illangama (3400 m), and a beans-maize system in the Alumbre (2000 m). All experiments included treatments involving tillage, crop residue management and fertilizer inputs. Here we report on yields, nutrient removal and uptake in these CAPS experiments.
