The systems of protective plantations transform agro-territories of the forest-steppe of the European part of Russia. With an area of artificial linear plantings in the Central Black soil region of 6 ha, negative natural phenomena and erosion processes in landscapes were significantly reduced. In windbreaks with fast-growing tree species, the highest growth rates are observed with a row spacing of 3.0 m and a tree spacing of 1.0 m. A convex transverse profile is formed in middle-aged stands, where the height of the middle rows is higher by 12.1 - 17.2% than in the extreme. The average tree growth continues up to 30 years. The growth rate is 0.73 - 0.83 m/year with the decrease from the age of 15-24 years. In the system of forest belts during the growing season, there is an increase in relative humidity of 1.8 - 9.8%, which altogether leads to an increase in the yield of grain crops by 330 - 550 kg/ha. The formation of plantings on the arable land of optimal parameters and structures will make it possible to have biological structures of long-term use with an increasing reclamation effect.
