Soil acidity, cation balance, exchangeable potassium status and cation retention capacity under K-bearing rock dust–organic amendment systems in a tropical Alfisol of southwestern Nigeria

Abstract Soil acidity and weak cation-holding conditions reduce nutrient-use efficiency in highly weathered tropical soils and constrain progress towards Sustainable Development Goals (SDGs) 2, 12 and 15. This study evaluated the 14-day soil chemical response to locally sourced p...
