Abstract :
Field geological study of the area revealed that the erosion hazard has remained active over the years, defying control measures put in place by government, communities and individuals. Assessments of effects of organic carbon content and water stable aggregates on the development of rill and gully erosion in Iloro, Ikoyi, Alele and Atiba of Aramoko Ekiti, Ekiti State, Nigeria is presented in this study. Soil samples were collected from different depths of gully sites and their geotechnical properties analyzed using organic carbon content and triaxial tests. Results revealed that the soil in the study area has low organic carbon ranges from 1.39 to 1.43 , which results in less organic carbon, thus high erosion. The triaxial test results ranges from 6 to 150. These could be deduced that the soil is vulnerable to agents of gully erosion such as rainfall, slope of land surface and human activities. An integrated approach including watershed management strategies, construction of ditches, retention pits at appropriate locations and a long term re vegetation strategy is suggested for controlling soil erosion and gulling in the study area.
