摘要

Abstract > Estimating symbiotic di‐nitrogen (N <sub>2</sub> ) fixation is challenging, especially when working with woody N <sub>2</sub> fixers in field trials. Fortunately, isotope methods based on 15 N natural abundance or on 15 N artificial enrichment (dilution method) make it possible to estimate the proportion of nitrogen derived from the atmosphere (Ndfa) in N <sub>2</sub> ‐fixing species. These methods have been extensively used in the field for herbaceous species, much less for tree species such as alder and acacia, and rarely for black locust ( Robinia pseudoacacia ). The objectives of this study were to characterize the fixation potential of black locust in a plantation by using the two 15 N isotope methods in the field, and to document values of isotope fractionation occurring during N <sub>2</sub> fixation (the B value). B values were estimated both by growing trees on an N‐free medium in controlled conditions ( B <sub>lab</sub> ) and by making Ndfa calculated with the natural abundance method converge with Ndfa calculated with the 15 N dilution method in the field ( B <sub>field</sub> ). The two methods gave consistent estimates of the B value. B values ranging between –1.4 and –3.2‰ were found, varying with the age of the plant material. Up to 76% of the N in the black locust trees came from the atmosphere, representing more than 45 kg N ha ?1 over five years and c </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display:
