Geospatial Analysis and Quadratic Regression Modelling of Soil Chemical Properties and Exchangeable Sodium in Aridisols of Sahel Savannah for Sustainable Soil Management

Soil degradation, particularly sodicity, constitutes a major constraint to soil fertility and sustainable irrigation agriculture in semi-arid environments. Exchangeable sodium (Exch. Na⁺) is a critical indicator of sodicity because its accumulation can impair soil structure, permeability and agricultural productivity....
