Abstract

Comparative analysis of degraded and non-degraded soils in Irepodun local government of kwara state Nigeria was carried out. Soil samples were collected from five different communities (Landmark University {representing Omu-aran}, Ipetu, Aran Orin, Oko, and Rore), all in Irepodun Local government of Kwara State, using random sampling. Auger samples were collected from each sampling unit at 0- 15cm. The physical and chemical properties of both degraded and non-degraded soils from these communities namely Omu-Aran, Ipetu, Aran-orin, Rore and Oko were examined. All the samples fell in into the textural class loamy sand with the exception of the degraded soil sample obtained from Aran- Orin. Non-degraded soils in all the study sites have higher values of N, P, K and Ca than degraded soils. Nitrogen in non-degraded samples ranges from (0.1 to 0.46cmol/kg/N), with Ipetu soil (IPND) having the highest and LUND having the lowest, While for degraded soils, the range is between (0.046- 0.09cmol/kg/N) for AOD and OKD respectively. CEC is seen lower in most of the non-degraded soils than in the degraded soils. Three of the five degraded soils samples (LUND, AOND and RORND) have higher CEC value, but lower in the remaining two samples. However, there is no correlation seen between pH and other soil parameters for the non-degraded soils. It was concluded that apart from leaching of basic cations that has led to degradation of soils, farmers also need to be trained on how to save the soil to reduce degradation. Ranging from the addition of soil amendments (organic manure, bio-fertilizers) to the use of integrated soil management practices, strategic steps must be employed to reclaim these soils and boost agricultural production in thearea.
