The chanelling is one of the most freqently applled anti-corosive soil processing in the countries that are advanced in the agrotechnical field. This present work discusses the changes of erosin parameters depending on the different depth of chanelling, applied to the inter-row distance of corn crop, not irrigated, the soil being medium erosive carbonate black earth of the average inclination 5 degrees. The depths that have been observed are as follows: 25 cm and 40 cm, the distance between chanlling being 1.4m. The results obtained out of the experiments, that have been realised, show that soils and liquid run-off decreases for the two depths. With the second depth (40 cm) the values of those parameters are better and it is more convenient with regard to soil - conservation.
