Grown for centuries by indigenous farmers in rural Mexico, this incredibly rare corn can self-fertilise. In episode three of 'Planet Fix', we explore how this wonder crop could help tackle world hunger, and even end farming's toxic reliance on chemical fertilisers for good!

    Well, no, nitrogen leaving the atmosphere is just not a concern. Biomass of all plants: 500 billion tons. Biomass of all human crops: 10 billion tons. Nitrogen’s share of plant mass: 3-4%, or 400 million tons. Mass of the atmosphere: 5.5 quadrillion tons. And most of the atmosphere is nitrogen.
