Abstract
Data are presented on the characteristics of growth and productivity of 36-year-old pine-larch crops on sodpodzolic weak-soddy sandy loam soils (1 category of forest suitability), in the steppe of southwestern Siberia. Larch has better growth rates than pine up to 23 years of age in diameter and up to 14–15 years in height. Then the leadership in growth goes to pine. The predominance of the volumetric indicator in pine occurs at the age of 28–30 years, and a more intensive increase in volume growth occurs from the age of 20 years. In the current forest conditions, local Scots pine is superior to Siberian larch of the Altai form in terms of preservation and taxation indicators. The supply of dampgrowing pine wood amounted to 281 m3/ha, or 75.4 % of the total. The identified features of the joint growth of two species in forest plantations should be taken into account when creating new plantings.
