Soybean seed chemical composition as influenced by Bradyrhizobium inoculation in soils with elevated nickel concentrations

Symbiotic nitrogen-fixing bacteria, rhizobia, besides their intrinsic ability to fix atmospheric nitrogen (N), may influence other element concentrations in leguminous plants. Adequate nickel (Ni) supply is of special importance for growth and N status of soybean, due to the role Ni holds as an enzyme component involved in N metabolism. However, high soil Ni availability also represents risks. Therefore, the objective of the study was to...
