Where
Aroressa district, Sidama region, Ethiopia ·
Why
Uniform nutrient management persists in Ethiopian highlands due to inadequate characterization of spatial soil heterogeneity, hindering agricultural productivity.
The Frontline Impact
How this affects you
The study successfully delineated five optimal nutrient management zones, significantly reducing within-zone variability for key soil properties like Potassium (74.2%) and Organic Carbon (49.3%). This supports a transition to site-specific nutrient management strategies, including variable-rate fertilization and targeted soil restoration, to improve agricultural productivity.
