Experiment Description:<\/strong><\/span><\/td>\nThe purpose of this experiment was to understand how nitrogen acquisition strategy, namely the ability to acquire nitrogen through symbiotic nitrogen fixation, influenced carbon costs to acquire nitrogen. The experiment quantified carbon costs to acquire nitrogen in Glycine max (soybean) seedlings that received one of two inoculation treatments (one without inoculation, one with inoculation of Bradyrhizobium japonicum) and one of two nitrogen fertilization treatments (70 ppm N, 630 ppm N) in a full-factorial greenhouse experiment.<\/span><\/td>\n<\/tr>\n

 Greenhouse experiment where soybean seedlings received one of two inoculation treatments (one without inoculation, one with inoculation of Bradyrhizobium japonicum<\/em>) and one of two nitrogen fertilization treatments (70 ppm N, 630 ppm N) in a full-factorial greenhouse experiment. Individuals were harvested after six weeks of development.<\/span><\/td>\nData are available on Zenodo: here<\/a><\/span><\/p>\n
