Publisher's Synopsis
Excerpt from The Influence of Waste Bark on Plant Growth
M AN Y pulp and paper manufacturers, including the Brown Company, Berlin, New Hampshire, have to dispose of several tons of fresh bark produced at the mill every day. Present practice is to truck it away and dump it. This necessitates the use of trucks, grading equipment and labor. Experiments, therefore, were started in an effort to discover, if possible, a profitable outlet for waste bark, including possible benefits to agriculture through soil improvement. A search of the literature reveals that very little work has been done on the effects of bark from pulpwood on soil and plants. Very little has been published on the subject. Rettie and Simmons (6) report that water-soaked bark, as it comes from the barking drums, contains upwards of 80 percent moisture. In this condition the fuel value is almost nil. Other reviews (5) indicate that bark may have possible industrial uses as well as soil building potentialities. Studies with sawdust (1, 3, 4, 7) applied either directly to soil or as compost show that when well decomposed it may in either case benefit plant growth. The experimental work with bark may be divided into two parts: (1) that dealing with greenhouse pot and bench cultures, and (2) field plot trials, and will be considered in that order.
