Soybean oil takes away the protein (nitrogen) but leaves most of the other nutrients in the meal. To be recycled as animal manure or sludge to refertilize future crops. The net loss can be quite low of real nutrients if we try.

Nitrogen can be supplied in many ways doesn’t need to be mined somewhere; and soybeans themselves supply their own N we don’t need to add any, so it is pretty close to ‘sustainable’ but I guess that depends on who is using that buzz word and how they want to define it.

Generally ‘sustainable’ is the code word to say farmers are the worst evil of the world and only non farmers know how farming should be done.
