⠀⠀⠀⠀⠀

Nitrogen-fixing bacteria in the soil saturate it with inorganic N-containing compounds, which are necessary crop nutrients. When fixation bacteria die, the accumulated N in their biomass is released into the soil. This way, they boost soil fertility naturally, allowing farmers to save on synthetic fertilizers.
