%K Development strategy of protective afforestation in the Russian Federation in the period up to 2020 plans to improve productivity and sustainability of agriculture. In condition of Central Black Earth Region will grow 148.300 hectares of field-protection plantations where they coot arable land is 1.26 %. Forest belts were created by woody, wood-handicraft, wood-typical methods and using a linear, square-cluster, diagonally group, block planting (seeding) and with the participation of poplars (balsamic, white, black, pyramid, etc.), silver birch, english oak, european ash, green, Chinese elm, acacia yellow, red elderberry, oleaster and others. A study of melioration feature of artificial protective forest are carried out in the period 1989-2014 years by conventional means, in taxation, forest plantations and agroforestry. Field-protection plantations of balsam poplar have the best growth when placing seats 3.0 x 1.0 m and a density of 3334 pcs. / ha, where an increase in the width and number of rows reduces biometric performance and safety of 4.0-8.3 % . This should be considered when creating agroforestry systems. In the forest belt of silver birch when placing seats 3.0 x 0.8 m safety and growth higher at 7.0-8.6 %, than in forest belt of other creation parameters. Mixed stands of birch, ash, oak and ash are more resistant and have higher biometric growth by 3.0-25.4 %, rather than pure stands. The greatest growth in height and diameter from balsam poplar, silver birch, english oak and european ash diagnosed at age 4-17 years. Field-protection plantations of purged and openwork structure is most strongly (by 9.9-17.6 %) increase in effect on productivity artificial phytocenoses (winter wheat) in closed to field areas up to 22-30 h (height).
