Windrowing Affects Early Growth of Slash Pine
On the Bradford Experimental Watersheds, Morris et al. (1983) previously demonstrated that, contrary to appearances, windrows were composed primarily (>85%) of soil rather than wood, and they contained large amounts of nutrients (e.g., about 333 lb nitrogen/ac of plantation). The present study addressed the question: do planted pines respond to such nutrient translocations? At five years of age planted slash pine (Pinus elliottii) on beds nearest windrows had 9%, 33%, and 45% more height, basal area, and volume, respectively, than trees three beds away. These are probably conservative estimates of differences due to better soil nutrition near windrows--because competing vegetation was much more abundant there. South J. Appl. For. 10:81-84, May 1986.
