Abstract

A trial comparing the effect of spot scarification and fertilization on stock types of coastal Douglas-fir was conducted in a 25-year-old backlog site in the CWHxm2. Bareroot and container stock types were planted and treated, and mortality and growth were measured for 3 years. Despite the high fertilizer-related mortality of the bareroot stock type in the first year, the 3-year height growth performance of all treatments was better but more variable than that of the untreated seedlings. The value of site preparation and fertilization for stimulating early growth varied by stock type. Bareroot stock type did not respond strongly enough to fertilization or site preparation to justify the cost of either of these treatments. Container stock types did not respond strongly enough to site preparation alone to justify the high cost of site preparation. The largest growth gains in the container stock types were associated with the combination of site preparation and fertilization.
