The paper presents the experimental results obtained in the period 2019-2021 regarding erosion and runoff processes, measured at standard plots for runoff control. They are located on the left slope of Tarnii Valley, Tutova Rolling Hills, eastern Romania, on soft soils (cambic chernozem), developed on a loamy substrate, moderately eroded, with a slope of 12%.The annual average of precipitation is 442.6 mm.The experience is composed of 10 parcels structured as follows: 8 parcels have an area of 100 m2, with a strip of grassy land 1 m wide, and there are 2 parcels that have an area of 150 m2.A number of eight plots were cultivated with various crops, such as: corn, wheat, beans, soy, sunflower and bromus. Two control plots, of 100 m2 and 150 m2, are maintained as permanent bare field.Also, annually, one of the cultures exists both in the 100 m2 and in the 150 m2 version. The average soil loss during the studied period was 0.0 t/ha/year for bromus, 0.274 t/ha/year for soybean, 1.220 t/ha/year for wheat, 2.503 t/ha/year for pea stubble, 11.083 t/ha/year in maize and 44.261 t/ha/year in permanent bare field
