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.

Highlights

Lands taken out from agricultural use have high soil fertility, which creates suitable environmental conditions for the restoration of natural landscapes [1,2,3,4,5]
It should be noted that pine plantations created on postagrogenic lands are characterized by large values of average height and diameter, as well as growing stock: one and a half to two times higher compared to pine plantations created on a former hayfield in a study area of the same age [4]
Assessments of the economic efficiency of production of wood chips from pine wood grown on postagrogenic lands included a set of machines and mechanisms, consumables and wages

Summary

Introduction

Lands taken out from agricultural use have high soil fertility, which creates suitable environmental conditions for the restoration of natural landscapes [1,2,3,4,5]. Productivity of forest plantations on such lands can be quite high. The efficiency of using financial, labor and material resources of the organization characterizes its performance; the latter should be aimed at increasing profitability of a tree plantation as an intensive growing model [10,11,12,13,14,15,16]. A commercial organization, when switching to new promising technologies and types of products when growing such plantations, requires investments in which profitability indicators may temporarily decrease, with proper strategic planning, the costs incurred will pay off in the future [17,18,19,20].
