Classification of Some Valley Bottom Soils in University of Ibadan
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2017, Vol 4, Issue 12
Abstract
Abstract:Wetland soils are very abundant in Nigeria, but due to poor understanding of their nature and properties, there is underutilization of these soils in Nigeria. Therefore, a detailed survey was carried out to classify some wetland soils in the Valley bottom of the University of Ibadan. Soil survey was conducted using rigid grid method; soil samples collected from genetic horizons were subjected to laboratory analysis using standard procedure. The soils were classified using the local system (Smyth and Montgomery 1962) at the lower level, while at the higher level using USDA Soil Taxonomy (2010) Soil Survey Staff, and World Reference Base for soil Resources (WRB, 2006) systems. Three soil types were identified from the study area. These include Jago Series (Smyth and Montgomery 1962); FluventicEutrudept (USDA Soil Taxonomy, 2010), FluvicGleysol (WRB 2006); Matako Series (Smyth and Montgomery 1962), FluventicEutrudept (USDA Soil Taxonomy, 2010), FluvicCambisol “Eutric” (WRB 2006); and Matako series “browner variation” (Smyth and Montgomery 1962), FluventicEutrudept(USDA Soil Taxonomy 2010), FluvicCambisol “chromic” (WRB 2006);. The soils are young, poorly drained and susceptible to flooding. Drainage and good soil fertility programme will be useful in managing the soils for increased productivity and crop yield.
