Abstract

Available soil nitrogen is frequently low in old-field plantings. Underplanting forage legumes and interplanting nitrogen-fixing shrubs can improve growth of hardwood saplings, especially black walnut and pecan. Most of the nitrogen-fixing shrubs and forbs have been introduced, and several are now considered invasive species. Research trials have been established on old-field sites to evaluate the potential benefits of establishing native forbs, grasses, shrubs, and trees with seedlings of black walnut, pecan, chestnut, and five oak species.
