Abstract

Results are presented from a restocking experiment on shallow peat investigating the effects of intensity of drainage and planting position on growth and foliar nutrient levels of Sitka spruce (Picea sitchensis (Bong.) Carr.). The previous crop of Sitka spruce had been felled prematurely after 36 years. Growth was significantly enhanced by drainage at 10m and 5m intervals, compared to an undrained control treatment, and by planting on mounds of spoil compared with planting directly into uncultivated soil. Foliar nitrogen concentration was significantly lower in undrained plots 16 years after planting. The physical or nutritional condition of the peat does not appear to have been improved by the first rotation crop.
