Soil structural properties and resistance to erosion might be increased by adding organic residues into soils. Farmyard manure and legume crops are among the most important organic residues. The main purpose of this experimental work was to investigate the effects of some organic residues, such as, manure and sorghum residues on the structural stability and erodibility of some surface soils. In this laboratory research, three soil samples with different textures were treated with two various kinds of organic residues at different rates. At the end of 13 week of incubation period, structural stability and erodibility of controls and mixtures were determined by means of structural stability index, dispersion ratio, erosion ratio, permeability ratio, aggregate stability and soil erodibility factor (K). As a result, the organic residues applied into the soils improved the structural stability and to some extent decreased the erodibility of soils studied. Keywords: Organic matter, erosion, erodibility factor, aggregate stability, dispersion ratio.
