Nitrogen fixation, the process by which nitrogen is converted to
ammonia, is vital for plants to survive and grow. However, only a very
small number of plants, most notably legumes (such as peas, beans and
lentils) have the ability to fix nitrogen from the atmosphere with the
help of nitrogen fixing bacteria. The vast majority of plants have to
obtain nitrogen from the soil, and for most crops currently being grown
across the world, this also means a reliance on synthetic nitrogen
fertilizer.
