DescriptionThe interplanting and underplanting of nodulated nitrogen-fixing plants in tree plantings can increase early growth and foliage nitrogen content of hardwoods, especially black walnut and pecan. Recent studies have demonstrated that some non-nodulated woody legumes may be capable of fixing significant levels of atmospheric nitrogen. The following nine nurse crop treatments were established with and without interplanted northern pecan: the nodulated legumes black locust, false indigo, and smooth false indigo; non-nodulated thornless honeylocust, Kentucky coffeetree, and redbud; non-leguminous buttonbush; 16N- 8P-8K tree food spikes; and a control without shrubs or fertilizer.
