Fertilization is one possible way of increasing the growth of forest stands. Results of the Cooperative Forest Fertilization Project have shown that the growth of red spruce (Picea rubens Sarg.) in unthinned natural stands in Maine can be increased considerably by fertilization with nitrogen. A series of experiments was performed to further determine the effect of fertilization on (1) the lignin content of the wood, (2) the alcohol/benzene extractables in the wood, and (3) the ash content. The results of the alcohol/benzene extraction analysis were taken as a measure of the waxes, fats, resins, and certain other ether-insoluble components of wood produced after fertilization.
