Estimation of Annual Erosion in Six Soil Series of the Federal University of Agriculture Abeokuta Nigeria using Rusle in Map Algebra
OYEDEPO, JA; OLAWALE, RA; OLUYEGE, DE & BABAJIDE, EI
Abstract
Anthropogenic activities such as deforestation, bush burning and extensive opening of farmlands in
the 10,000 hectares at the Federal University of Agriculture, Abeokuta (FUNAAB) have increased vulnerabilities of
the seven soil series in the campus to agents of erosion. Therefore it is important to evaluate the rate and locations of
soil erosion in the study area inorder to develop erosion control intervention programme using standard methods. The
results show that overall soil erosion ranges from 0 to 167.8 tons per hectare per annum. 10% of University land now
has high risk of soil erosion being grasslands exposed to annual fires. Soil erosion is pronounced in the two soil series
(Oke-imesi and Apomu) that are found along river fringes with topographic factors (Slope length and steepness) playing
major role in the soil erosion
