A Review . . . Fiber, Chemical, and Agricultural Products from Southern Pine Bark

Published information on fiber, chemical, and agricultural products from southern pine bark is reviewed. Southern pine barks do not yet appear uniquely attractive for many uses. They do not appear competitive as a source of tanning extracts and cannot compete with wood waste by hydrolysis to sugars. Their sugars do not appear competitive with spent sulfite as a base for yeast growth. They cannot compete with western barks as a source of wax, cork, and flavonoids. They do compare favorably in lignin content, extractable polyphenols, and rate of deterioration for soil and humus building. Also, their manufacturing source is much nearer to large eastern population centers. Most promising immediate uses of southern pine bark appear to be as fuel and soil amendments.
