English title: Effects of drain spacing on the economic results of forest drainage investmentsAbstract
The aim of the study was to determine how the spacing of drains affects the economic results of forest drainage projects. On the basis of empirical material consisting of 411 sample plots, it is presented marginal cost curves showing how many meters more of drains it is needed to increase the value of stock, 35 years after the drainage, by a value equivalent of one cu.m of coniferous pulpwood. Results indicate that wider spacings ought to be used on poor sites, on sloping swamps, and in the north.
