The effects of two nitrogenous fertilizers, applied on bare ground in October and on 70 cm of snow in February, were studied in a 15-year-old lodgepole pine (Pinus contorta Dougl. var. latifolia Engelm.) stand near Spillimacheen, B.C. Fertilizers were applied at three stocking levels: 16 000, 2500 and 800 stems ha-1. Urea (300 kg N ha-1) was applied on bare ground and on snow, whereas ammonium nitrate (300 kg N ha-1) was applied only on snow. Over a 3 year period, height growth was not significantly affected by any treatment. Absolute volume growth was significantly (P
