The scientific article considers methods for studying the underlying surface of agro landscapes of slope lands - local and integral: contact and non-contact. Each group in turn includes a visual, optical and mechanical approach. For carrying out experimental studies on sloping lands, a method has been developed for determining the average slope, roughness and waviness of an elementary site in the field, and profilographs for its implementation. Using the moving average method, it is possible to break the data into components and isolate, on a general background, the average surface slope, randomly distributed irregularities, surface roughness and technological furrows with a corrugation of the surface. In order to automate the process of determining these parameters, a program has been developed that allows you to directly calculate and display information on the monitor screen. Field studies using a profiler with contactless profilograph were conducted on different soil fertility, including the examination of the field station, located on the slope of the complex after the pre-winter tillage BDM-3x4P in Morgaushskiy District of the Chuvash Republic. After data processing, the average slope of the elementary area for a certain point of the field was 0.06 or 3.440. The direction of the main soil cultivation was determined from the angle of deviation of the technological grooves from the direction of the slope, which amounted to 93.60. The data obtained are presented in the Excel spreadsheet as a relationship between two parameters: the angle of rotation and the height of the surface profile of the soil, in the form of a sweep. Further, using the moving average method for the field section with soil disking, the average slope of the surface was determined to be 3.440, the surface roughness was 3.54 mm, and the waviness (soreness) of the soil surface was 7.94 cm.
