Topographic Position and Soil Depth Govern Spatial Variability of Soil Physicochemical Properties and Fertility Status along a Humid Tropical Toposequence in University of Uyo Teaching and Research Farm, Akwa Ibom State Nigeria
Topographic position and soil depth are among the principal factors governing soil formation, nutrient redistribution, and spatial variability of soil fertility in tropical landscapes. Understanding their influence on soil physicochemical properties is essential for developing site-specific soil fertility management st...
