A two –year (2004/2005) field investigation was carried out on the runoff plots at the University of Nigeria Nsukka farm, to monitor the effects of cover management practices on physical properties, runoff and soil loss in Nkpologu sandy loam soil. The management practices werebarefallow (BF), cocoyam (CY) sorghum (SG), legume (CP) and grass (PM), under no-tillpractice. There was no change in soil texture due to treatments. The treatments generally increased soil organic matter content compared with the control. Bulk density was significantly increased in all treatments with highest value (1.65Mg/m3) in barefallow and lowest value (1.49Mg/m3) in grass. There was no significant decrease in porosity and pore size distribution. Meanweight diameter (MWD) of aggregates and saturated hydraulic conductivity (Ksat) were significantly increased (p = 0.05).
