Donaldsonville, CF Industries, is one of the biggest Ammonia plants in the US. What we are just passing in our canoes is a planetary reactor: nitrogen from the atmosphere is put together with hydrogen from natural gas from the lithosphere, to make the industrial biosphere grow faster. The production of artificial ammonia from the elements by help of an already artificial iron-kali-potash catalyst was high-tech in 1910. But it is still this process that makes industrial agriculture work.
From Donaldsonville nitrogen products are shipped into the world as we just see at the terminal of the plant. But even if they go upstream to fertilize the soy and corn belts, most of the industrial molecules would see the place of their production in Donaldsonville again, as they are washed from the fields into the rivers and thus into the Mississippi river flowing by.
