Future research should investigate the effects of climate change on soil nitrogen cycling in different ecosystems. Studies should examine the potential for compensatory biological nitrogen fixation to offset soil nitrogen depletion. Research should also explore new strategies to maintain soil nitrogen stocks and ensure the long-term sustainability of intensively managed agroecosystems.
