Phosphorus fractionation and distribution in Nitisols of the central Ethiopian highlands affects soil nutrient management strategies in barley (<i>Hordeum vulgare</i> L.) production.

ABSTRACT: Optimizing nutrient management is essential for sustaining crop productivity on fertilizer-unresponsive acidic soils, particularly through a comprehensive understanding of soil phosphorus (P) dynamics. Phosphorus availability is often limited by soil physicochemical properties, necessitating site-specific amendment strategies. This study evaluated the status of inorganic P fractions and their response to various nutrient and soil amendment treatments in acidic Nitisols from Welmera and Ejere districts in the central Ethiopian highlands, with a focus on barley (Hordeum vulgare), a crop that is sensitive to low soil pH. Field and laboratory investigations revealed that strongly acidic soils responded positively to lime application combined with optimal P fertilization, resulting in si
