What happens is lightning causes oxygen and nitrogen to combine and form nitrogen oxide, a key ingredient in many fertilizers.

Lightning provides the intense energy needed to combine atmospheric nitrogen and oxygen into nitrates. The rain then carries these nitrates down to the earth’s surface enriching the soil. Acting as a fertilizer, nitrates in an indirect way helps make the grass green.
