Abstract. The achievements of world science and technology provide an opportunity to increase the productivity of sloping agricul- tural ground (first and foremost arable land) by different kinds of land reclamation, fertilizer, etc. Given the General high culture of farming and a significant basis of productivity runoff-regulating forest belt (SLP) also have a significant impact on improv- ing the gross yield of agricultural crops by preventing erosion processes and further detention of precipitation. In this article to assess the effectiveness of anti-erosion forest reclamation in the current environmental and economic conditions presented a detailed analysis of dynamics of basic agro-economic indicators in the change of locality incline, degree of soil erosion and bioengineering parameters of forests. Given models of calculation of zonal (for climatic zones forest-steppe — dry-steppe) parameters of the discounted and over the life agro-economic effect. It is established that the most significant size of prevented from using the forest reclamation of post-harvest losses of basic grain crops is achieved when the locality incline 5.1–6.0° on highly eroded soils (3.8–5.4 thousand rub./ha of arable ground), additional net income from crop products — at a locality in- cline 2.1–3.0° on weakly eroded soils (2.6–4.2 thousand rub./ha). Use early maturing breeds are increases the average annual (discounted) the effect on 20–26 %. On the functional durability the greatest benefit in the forest-steppe and steppe receive from agroforestry arrangement of agricultural land system durable plantings — 70–240 thousand rub from 1 ha undeveloped site. On chestnut soils of dry-steppe at 10–14 % is effectively growing early-maturing breeds. The conducted research will improve the economic feasibility of agroforestry interventions to assess the different modes of afforestation of sloping arable land.
