| Popis: | Results of fundamental and applied studies of V. N. Sukachev Institute of Forest Russian Academy of Sciences, Siberian Branch and the Research Institute for Agrarian Problems of Khakassia, Federal Agency of Scientific Organizations of Russia in soil deflation control using management, also agrotechnological and agroafforestation measures, have been given in this scientific review. These activities were undertaken for 55 years. It was established that an average annual humus loss on arable lands in the south of Central Siberia made 1.6 t per 1 ha in the result of soil erosion. The system of usage and protection of soils subjected to erosion has been considered which covers the net of forest shelter belts, strip planting of agricultural crops, application of soil protective farming equipment and fertilizing. In the result of complex studies of soils prone to erosion the following activities were worked out: the way for fertility increase of sandy-loam soils by deep application of organic fertilizers; the way for growing the Siberian larch shelter forests; the way for growing the shelter stands using diagonally- wide meshed construction; the way for growing stands on slope pastures; the technology for growing the two-row shelter forests with a wide row- spacing; ways for growing stands for cattle-breeding purpose; ways for growing massive Scots pine stands; principles of choice of trees and bushes for shelter forests; the main standards for evaluation of linear steppe stands in the south of Krasnoyarsk Krai, Khakass Republic and the Republic of Tyva; concept for growing a new generation of shelter forests ect. Protective forest stands established in the south of Central Siberia in the area more than 50 thousand ha are shown to give a new environmental effect resulting in an increase of soil fertility and crop capacity. Studies of tactical and perspective levels have been shown in the paper, realization of which will promote solving the problems of research progress. |
