Abstract

An investigation was conducted over a period of five years to test the hillculture crop value of various Iowa sumacs as erosion control and economic, tannin-producing plants. The latter phase included the study of the quality and quantity of tannin produced by comparing the species, analyzing the parts of the plants, interpreting the factors affecting the "yield and conducting an experimental harvesting and processing project at the Hillculture Experimental Station near Floris, Iowa. Four species of sumac growing in Iowa were chosen for observation and possible investigation. These species were Rhus aromatica Ait., fragrant or aromatic sumac, Rhus copallina L., black or dwarf sumac, Rhus glabra L. white or smooth sumac, and Rhus typhina Torn., staghorn sumac. Another related plant, Toxicodendron radicans (L.) Kuntze, poison ivy, might have been studied had this species been safe to handle. Rhus trilobata Nutt. occurs in a few places in Iowa but sufficient quantity of this species was not available for consideration. R. copallina was selected because it had been the most used by commercial tanners in the east. R. glabra was included because it seemed to have possibilities for production in Iowa due to its vigorous growth, large leaf and long leaf stem and petiole. Because R. aromatica and R. typhina appear abundantly in localized areas of Iowa, these two species were included in the project.
