Erodibility of UNAAB soil series for nine plots behind the female hostel ( i.e. plot A – I) using regression equation were determined by evaluating first organic matter content, using the Walky Blanks method, the particle size analysis, permeability test, bulk density and chemical properties of the soil such as Sodium, Cation Exchange Capacity, acidity, Potassium, Magnessium and calcium.
The organic matter content of the soil(Ibadan series-sandy loam) was found to be;plot1 depthA&B( 2.017%, 2.133%),plot2 depthA&B(2.084%, 2.133%),plot3 depthA&B( 1.278%, 1.307%),plot4 depthA&B( 1.200%, 1.221%),plot5 depthA&B( 2.622%,2.734%),plot6depthA&B(1.523%,1.549%),plot7depthA&B(1.479%,1.514%),plo t8 depthA&B(3.967%,4.058%),plot 9depthA&B(1.143%,1.169%) and the average particle size was fou.3nd to be; plot1(87.05% sand, 1.79% clay,11.5% silt),plot2(86.8%sand,1.85%silt,11.5%clay),plot3(84.7%sand,2.8%silt,12.5%clay),plot4( 86.0%sand,3.8%silt,10.5%clay),plot5(86.0%sand,3.3%silt,11.5%clay),plot6(87.3%sand, 2.5%silt,9.8%clay),plot7(87.3%sand,1.0%silt,11.4%clay),plot8(83.8%sand,4.7%silt,11.4 %clay),plot9(86.3%sand,3.3%silt,11.5%clay).This confirms the earlier report that the soil can be classified as Ibadan series.
The erodibility values (factor) for the plot were determined as follows: plot 1,depth A&B(0.00000922,0.003587), plot2 depthA&B(0.00346,0.00383),plot3 depth A&B(0.0212, 0.00354),plot4 (0.003966, 0.00397),plot5 deptA&B(0.003304,0.003255),plot6 deptA&B( 0.004088, 0.004088),plot7 depthA&B( 0.003673, 0.000354),plot8 depthA&B( 0.002805, 0.00335),plot 9 depthA&B( 0.003957, 0.003756). The values of erodibilities as presented is low and this indicate that the soil will be susceptible to erosion.Both terrace and strip cropping conservation measure is therefore recommended to curb erosion menace as witnessed in the area.

CHAPTER ONE INTRODUCTION Maryland is located in Enugu South in Enugu State. The subsoil of this region consists of fine grained soils with a considerable part of soft soil deposit which extends to a considerable depth. When a compressive load is applied to a soil mass, the volume of the soil mass tends to reduce, due to reduction in... Continue Reading
