Abstract
This study was designed to assess the fertility potential of agricultural soils for optimal and sustainable production. Soils under five land uses were characterized and evaluated for fertility status using Fertility Capability Classification (FCC) systems. The results showed that the morphology, physical, and chemical properties of the soils varied from one land type to another in all the five land use types with the major differences being in texture, structure, colour, drainage, and soil consistence. The FCC systems classified pedons in land use 1 as Leg’ (Loamy acidic moist), Cevd’’ (Clayey acidic dry), and Led’’ (Loamy acidic dry); land use 2 as Le’’ (Loamy acidic), and SLe’ (Sandy Loam acidic); land use 3 as Le’’ and Led’’; land use 4 as Le, Le’ and SLe; and land use 5 as Leg’, SLe’’ and Led soils. The FCC results showed that the basic differences between soils in all land use types examined were in the texture and condition modifiers with low ECEC (e) and gravel concentration (‘ and ‘’), being most prominent. In order to improve the productive capacity of the soils, the application of inorganic fertilizer and organic manures, cultivation of cover crops, and correct usage of the land for the purpose it is best suited are recommended.
