Growth of larch stands on former arable lands
Discusses the economic situation related to the bankruptcy of a significant number of agricultural enterprises and the exclusion from agricultural use of former agricultural land with low productive soils. The question of the need of man-made forests growing economically valuable species, they are much more productive, since many areas of former arable lands, hayfields and pastures overgrown with shrubs, the species composition of which indicates ineffective use of land resources data. Recommendations on increase of efficiency of use of former agricultural land. In the process of studies from five sample plots analyzed the productivity of 63-year-old plantations of Larix sukaczewii. It is established that in the specified forest reserve stem wood depends on the density of forest stands and reaches 618 m3/ha. The currently used table significantly overstate the stock of forest stands, thus necessitating the development of regional tables of quantities for artificial larch forest stands established on former agricultural lands. The high productivity of larch forest stands established on former arable lands, allows us to recommend the creation of artificial plantations of this breed in predisaster pine-birch forests of the TRANS-Ural plain province of the West Siberian lowland forest area. This approach will improve the efficiency of land use through the cultivation of highly productive forest stands and will ensure real carbon sequestration, i.e. the implementation of the Kyoto agreement. Planting larch will ensure the creation of firebreaks and reduce the possibility of the spread of forest fires on agricultural land. The findings also stated that currently used on the production volume table for Larix sukaczewii are very different, which makes it necessary to develop regional tables for artificial stands.
