CAN WOOD CONTRIBUTE TO SOIL IMPROVEMENT?
SAWDUST, WOOD CHIPS & SHAVINGS, AND WOODY PLANT STEMS ARE CONSIDERED TO BE VERY VALUABLE SOURCES OF SOIL ORGANIC MATTER. WOOD CONTAINS LARGE PERCENTAGES OF LIGNIN WHICH IS BROKEN DOWN INTO A HUMUS MUCH LONGER LASTING THAN A HUMUS OF ORGANIC MATTER HIGH IN CELLULOSE DERIVED FROM THE BACTERIAL DESTRUCTION OF PLOWED UNDER GREEN MANURE CROPS. LARGE AMOUNTS OF SAWDUST, WOOD CHIPS AND SHAVINGS, AND PLANT STEMS MAY BE ADMIXED WITH SOIL TO THE BENEFIT OF CROPS OR GROUND COVER PLANTS PROVIDED ADEQUATE NITROGENOUS FERTILIZERS ARE ADDED IN THE PROCESS OF SOIL IMPROVEMENT. MULCHES DERIVED FROM WOOD CAN BE CHEAPLY MANUFACTURED BY PORTABLE "HOGS" AND GRINDERS NOW AVAILABLE. HEAVY SAWDUST OR WOOD SHAVING MULCHES HAVE BEEN USED IN IMPROVING SOILS AND INCREASING THE PRODUCTION OF ORCHARD CROPS. /AUTHOR/
