Growth of Douglas-Fir Seedling in California Nursery Vary Little Under Four Fertilizer Regimes

Producing good quality nursery stock at the lowest possible cost is a continuing goal in plantation work. In the spring of 1965, the California Regional Office and the Six Rivers National Forest set up a fertilizer test at the Humboldt Nursery in north-coastal California. The species studied was Douglas-fir Pseudotsuga menziesii var. menziesii) , normally shipped by the nursery to the field as 2-0 stock. The test aimed at developing a satisfactory onceper- crop, or once-per-year fertilization program by using slowly soluble fertilizers in granular form rather than the highly soluble fertilizers currently used. The stock then being produced had generally shown good survival and growth after field planting.
