FERTILITY CAPABILITY CLASSIFICATION OF SOILS OF OGBESE RIVER FLOODPLAIN, SOUTHWEST NIGERIA
The potentials of wetlands have remained relatively untapped and under-utilized in rural West Africa as a result of the neglect of most of the floodplain soils due to absence of useful pedological information on them over the years.

| Riassunto: | The potentials of wetlands have remained relatively untapped and under-utilized in rural West Africa as a result of the neglect of most of the floodplain soils due to absence of useful pedological information on them over the years. Therefore, the objective of this study is to evaluate the Fertility Capability Classes of floodplain soils in the upper basin of Ogbese river. The study was conducted at Ogbese in Akure North Local Government Area of Ondo State, Southwest Nigeria. Nine soil profile pits were dug and described along three transects (i.e. upper reach, middle reach and lower reach) within the floodplain. Soil samples were collected from pedogenic horizons for laboratory analyses of physical and chemical properties that are directly related to plant growth following standard procedures. The results showed that six FCC dominated the floodplain. SLke characterized by sandy topsoil, loamy subsoil, low nutrient capital reserve and high leaching potential; SLgke characterized by sandy topsoil, loamy subsoil, gleying, low nutrient capital reserve and high leaching potential; Lke characterized by loamy topsoil and subsoil, low capital nutrient reserve and high leaching potential. Ske characterized by sandy topsoil and subsoil, low capital nutrient reserve and high leaching potential; LCke characterized by loamy topsoil, clay subsoil, low nutrient capital reserve and high leaching potential; LCgke characterized by loamy topsoil, clay subsoil, gleying, low nutrient capital reserve and high leaching potential; SLgke, LCke and LCgke classes had higher potential for high yield in arable crop production than other classes in the study area. |
