AbstractA nitrogen and phosphorus fertiliser experiment on Sitka spruce (Picea sirchensis (Bong.) Carr.), which had been running since 1967, was subdivided in 1977. Half of the original experimental plots were left untreated, half received lime and further applications of nitrogen and phosphorus in factorial combination. In the plots of the section unlimed and unfertilised in 1977, the 1967 fertiliser application has shortened the rotation by 6 to 9 years. The section limed and fertilised in 1977 showed growth responses to the new applications of nitrogen and phosphorus. Nevertheless, the indications were that the unlimed trees were superior to those which had been limed. The results indicate that no benefit is to be gained from liming under these circumstances. There is no evidence of nitrogen deficiency in either experiment, but it is possible that further applications of phosphate will prove beneficial.
