A Note on Effects of Sewage Effluent Irrigation on Specific Gravity and Growth Rate of White and Red Oaks

P. S. Szopa, L. C. Tennyson, E. A. McGinnes

Abstract


A 2.5-acre forested terrace of mixed hardwoods (predominately oak) in southern Missouri was sprinkler-irrigated with treated sewage effluent. Ninety-two oak trees were sampled (increment cores) at breast height. There were 41 white oaks and 52 red oaks. Growth rate increased significantly for white oaks and specific gravity increased significantly for red oaks.
