The main subject of research in this paper is the cost of cultivation in chosen forestry divisions which are based in the area of Regional Directorate of State Forests Szczecinek in years 2011-2015. The aim was to verify if the relationship between amount of costs incurred and if the fertility of the habitat exists.
To conduct analysis six cultivation treatments were chosen: soil care, early cleansing, late cleansing, late cleansing with acquisition of the mass, early and late thinning. Cultivation treatments were carried out in selected types of forest habitat (TSL). Research results demonstrated that late thinning is the most expensive treatment. Research also proved that type of habitat has an effect on costs endured.
