Abstract
The article states that under the conditions of gray-meadow soils, the influence of laser leveling of the earth's surface on the amount of humus and nutrients. Soil nutrients depend on the evenness of the field surface in fields that are leveled, laser leveling shows a uniform distribution of mobile nutrients over the surface and soil layers. As a result of uniform distribution of irrigation water over the soil surface, the amount of mobile nutrient elements is reduced.
