Comparitive Growth of Black Spruce Container Seedlings Grown in Worm-Casting-Amended Soilless Media

Black spruce (Picea mariana (Mill.) B.S.P.) container seedlings grown in peat vermiculite amended with pig manure worm castings at two concentrations and sewage sludge worm castings at three concentrations were compared with and without fertilization to seedlings grown in peat-vermiculite without amendments. In general, we found that non-fertilized seedlings grown in medium amended with 10% pig manure castings showed the best growth of any of the seedlings. Concentrations of foliar macroelements and microelements (except zinc) were within an acceptable range for container seedlings. Tree Planters' Notes 43(2):43-47; 1992.
