"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!"

What does self fertilization have to do with ending farming's toxic reliance on chemical fertilizers?

In this case "self fertilization" refers to fixing nitrogen, not "fertilizing" in the sense of reproduction.

Knowing exactly how much nitrogen they can fix is important. It's unlikely to be enough to take care of the nitrogen requirements of high yield corn.

Context: Most plants pull nitrogen from the soil, and over time the soil becomes depleted and your crops grow more slowly. Bacteria in legumes convert atmospheric nitrogen to plant-usable forms, so historically you've needed to cycle nitrogen-"fixing" crops into your fields to 'restore' the nitrogen balance in the soil. Alternatively, you can use fertilizers, which supply N directly.

This is potentially interesting because the corn acts as its own fertilizer, fixing nitrogen from the atmosphere.
