Note générale :	Some physical properties of the surface and profile soils of the loes plain soil unit of Northen Nigeria are presented - The transported soil material extending to a depth of some 5 feet has the bulk of particle size between 2u-5u diameter. The clay fraction inereases in depth from about 13 pr cent at the surface to about 40 per cent at its base. The partiele densite of the transported material is less than 2.66g/cc. The sedentary portion of the profile contains varied proportion of stones and gravel and has distinethy higher proportion of coorser partieles. The specific granty of soil partieles is higher than 2.66 g/cc. The total porotity of the profile ranges from 46-34 per cent, with the porosity of the transported section of the profile above 40 per cent. Low porosity of the surface sol is a reflection of poor structural condition.
