In 1967, urea was spread by hand at a rate of 50 kg active ingredient per ha in a pure Scots Pine stand of age class IV [60-80 years] and site class III. Data are given on diameter increment for 5 years before and 5 years after the treatment. The average increase in diameter increment was 15% and in volume 18%, this representing 0.56 m3 per ha per year.
