Investigations have shown that, quite independently from the sort and quality of the soil, the best valuation was given to the beech cover on low situated land (1-1.2) and on slopes (1-1.8). On sandy elevated ground (clay sands) and on flatland (no matter what kind of soil), it received somewhat worse valuation (1.2-11.1 and 1.3-11.3 accordingly), while the worst valuation was observed on clayey ridges (11.6-111.0).
