The aim of this study was to determine the effects of organic wastes such as bio-solid (BS) and tea waste (TW) on erosion ratio index (ER) of eroded soils in different levels (slight, moderate and severe). Soil samples used in this research were taken from surface soil (0-20 cm depth) located on agricultural land of Samsun province in the northern part of Turkey. These soil samples were treated with organic residues at four different levels (0, 2, 4, and 6% basis w/w) and each treatment was replicated three times in a split block design. All pot mixtures were incubated for 4 weeks under greenhouse conditions and later tomato plants were grown in all pots. When plant growth was in its 14th week, the experiment was ended. After greenhouse work, changes in ER values of eroded soils were determined. It was detenuined that the BS and TW treatments dramatically decreased ER values of the eroded soils compared to the control treatment. Statistical test results showed that erosion level (p <0.001), type of residue (p <0.01) and the application dose (p <0.001) caused the changes of the ER values.
