Nitrogen is the principal nutrient limiting life in the biosphere. Population growth has made food security an international priority. However, the drive for yield alone has led to very high application of nitrogen, leading to substantial contamination of groundwater and associated problems of regional, national and international scope. An alternative to added nitrogenous fertilizer is biological nitrogen fixation from legumes. How this process might be used effectively to help ameliorate the nitrogen crisis will be discussed.
