Analysis of Physico-chemical and Hydraulic Characteristics of Soil in Forest Area of Southwestern, Nigeria

In this area of agricultural transformation by the government of Nigeria, every opportunity in order to achieve food security should not be ignored. Most studies on soil characteristics had centered on the suitability of the soil for agricultural   production and it is observed that any soil that does not support crop production refers to as poor and unproductive. Achieving efficient production and high yield requires adequate knowledge of the soil and climatic conditions that are favorable to the crops. The study was conducted to investigates physico-chemical and hydraulic properties of forest soils in southwestern, Nigeria in latitude 7o5’3’’N and 7o 21’57.6’N and longitude 5o 10’31’’E and 5o56’6.3’’E. The soil samples were randomly taken from four (4) forest locations in Ondo State, Nigeria. The soils were taken at different depths (0-15 cm, 15-30 cm, and 30-45 cm) and the samples were taken to the laboratory in order to determine their pH, electrical conductivity, exchangeable cations, and texture. The results of the soil test were then subjected to appropriate statistical analyses. Results show that sandy soil had the highest percentage in the forest at kajola oju-irin (70%). The bulk density is high in Ijare with 1.6 g/cm3 which could allow easy penetration of water and nutrient. Also, the soil pH, electrical conductivity and exchangeable cations range from 4.65 to 6.99,78.28 to 89.20 mS/cm and 0.40 cmol/kg to  2.60 cmol/kg respectively. The soils are described as light and falls under sandy loam soil. This study provides information on the suitability of the soils in the forest areas in south west Nigeria.
