Physicochemical Properties, Degradation Rate and Vulnerability Potential of Soils Formed on Coastal Plain Sands in Southeast, Nigeria

Ackley Ufot Akpan-Idiok

Abstract:
The aim of this research was to study the physicochemical properties, degradation rates and vulnerability potential of coastal plain soils and suggest appropriate management strategies. Twenty composite soil samples (0-15 and 15-30 cm) collected from agricultural lands at ten locations in Akpabuyo Local Government Area of Cross River State of Nigeria were studied. The soils were characterized as follows: texture of loamy sand surface overlying sandy loam subsurface; pH (4.9-5.2), organic carbon (4.2-26.5 g kg-1), total nitrogen (0.4-2.2 g kg-1), carbon-nitrogen ratio (11-18), available P (45-73 mg kg-1), effective Cation Exchange Capacity (CEC) (2.63-5.52 cmol kg-1), base saturation (39-92%), Ca:Mg ratio (1.50-3.00) and Mg:K ratio (2.94-20.00). The Soil Degradation Rate (SDR)/Vulnerability potential (Vp) weighted values of texture (4/2), soil pH(H2O) (5/1), organic carbon (4/2), total nitrogen (1/5) and effective cation exchange capacity (2/4) showed susceptibility of the soils to degradation or vulnerability. The soils could be managed by liming, planting of acid tolerant species and adopting appropriate cultural practices.
