I think at that point they just didn't have any money left to import fertilizer. You can grow organic but not on soil that has been fertilized for years. The soil is completely dead and any water you pour into it will more or less vanish instantly. You probably need a decade or two to fertilize is naturally. Of course you also need a lot more land as you need crop rotations and the soil needs time to regenerate.
