    An important feature of crop-forest integration (ICF) systems is the creation of a microclimate in the area in which it is deployed. The objective of this work was to evaluate the application quality and soil losses in soybean crop in monoculture and crop-forest integration areas. The work consisted of two experimental fields. The first was installed in the crop-forest integration system of the State University of Northern Paraná (UENP). The second was installed in a monoculture system, located 300 meters from the first field. The experimental design was randomized blocks, composed of 6 treatments in a 3x2 factorial scheme, being 3 classes of drops (very fine, fine and medium) and 2 periods of the day (morning and afternoon), with 4 repetitions. Temperature, air humidity and wind velocity were measured during the application of each plot in both experimental fields. The spray mixture used to apply the treatments consisted of water, FD&C Bright Blue marker dye (0.6 %, v v⁻¹) and fluorescent dye LRM 100 (0.6 %, v v⁻¹). Subsequently, the application quality was evaluated by the deposit (mg L⁻¹) and leaf coverage (%). Soil losses were also evaluated. The conditions of temperature, relative humidity and wind speed were influenced by the cultivation system present in the area. Soil losses were higher in the monoculture system. However, deposit (mg L⁻¹) and coverage (%) values were higher in the monoculture system when compared to the ICF system.
