Abstract The paper examines economic efficiency of obtaining wood biomass through accelerated cultivation of pine on postagrogenic lands of the Leningrad Region of Northwest Russia. In experimental pine plantations, we selected model trees and calculated the stem wood biomass of 11-year old stands with different stem densities. Assessments of the economic efficiency of the production of wood chips from pine wood grown on postagrogenic lands were based on a set of machines and mechanisms, consumables and wages. A break-even point was determined for the production of wood chips in plantations with different stem densities. In the variant with a stand density of 2900 trees per hectare, it is possible to make a profit, because a break-even point was obtained for the investments made. Pine stands of such density can be taken as a prototype, when creating and growing short rotation plantations. Based on the results of the study, it is possible to predict a further increase in pine wood biomass in a plantation on post-agrogenic soils. On postagrogenic lands, marketable wood pulp can be obtained within a short period of time; thus such lands will be involved in an economic turnover.
