Book excerpt: The Interprovincial Forest Fertilization Program comprises 81 standardized experiments established by the provincial forest services of New Brunswick, Quebec, Ontario, Manitoba, and Alberta, and by the Canadian Forestry Service in the provinces of Nova Scotia and Saskatchewan. Seventy-three experiments were remeasured after 10 growing seasons. The field trials were designed to test the effect of nitrogen when applied as urea at the rates of 112 and 224 kg/ha, and the effects of combined nitrogen, phosphorus, and/or potassium additions on the growth of pole-size and semimature conifer stands. In the combination treatments, nitrogen was applied at the high rate, phosphorus as triple super phosphate at the rate of 112 kg/ha, and potassium as potassium chloride, also at the rate of 112 kg/ha. This final report contains the 10-year response data, with sections of the 5-year report included to present a more complete picture.
