Summary:The investigation is focused on the conditional characteristics of the soil on the erosion-threatened sloping lands devoted to agriculture. The studied territory is situated in the Equatorial Andes. The analyzed samples were taken from the key-sites located on the slopes with inclinationangle of 10°. The comparative analysis was carried out within the borders of a key-site divided into 4 sectors with different agricultural crops: corn, oats, beans and a permanent grass pasture. It is defined that the agricultural fields used for corn cultivation are the most vulnerable to erosion. The organic matter content in the plow layer is decreasing up to 0,53 %. The process of erosion is the leading degradation factor. Observationshave shown that such erosion forms as gullies are being formed. It is recommended to reduce corn cultivation in steeply inclined areas unless erosion control measures are taken.
