Morphological signs of soil are one of the main indicators of soil properties. As a result of cultivation and irrigation of soils, there are great changes in its morphological characteristics. The article presents the morphological characteristics of soil sections placed in the old part of Mirzachol. In order to compare the changes in the morphological characteristics of the soil, repeated soil sections were placed in the areas where the previous soil sections were placed and studies were conducted. As a result of the increase in the duration of development and irrigation, it was noted that there were changes in the depth of the arable layer, the color of the soil, the gypsum layer, and the depth of the carbonates.
