Studies were conducted in the equatorial Andes, in the region of the canton of Latacunga, Republic of Ecuador. A comparison was made of eroded soils on the slopes with corn crops and pasture areas. In the soil sectors occupied by corn, a low organic matter content of 0.31–0.82% is revealed. Pasture soil soils have indicators of 1.67–1.71%. It has been established that the cultivation of corn on steeply inclined slopes in the mountainous part of Ecuador leads to significant erosion degradation of land.
