OK sustainability goes further than just taking care of the soil.
Lets look at seed. You buy seed that won't grow a subsequent crop. (I know it's not going to happen) The seed companies all fail for what ever reason. What are you planting the next year. Therefore, long term, those seeds were not sustainable. Some soil experts are claiming that with no other inputs other than chemical fertilizer and no till eventually the soil will get to the point where it requires so much chem ferts that it's no longer profitable to plant, therefor not sustainable. They are claiming that organic material, manure, crop residue ECT needs to be put into the soil as well as any needed chemical fertilizers. Rotational grazing or some other method of taking care of the soil in a pasture. Raising animals instead of buying feeders because if the market for feeders drys up. Just kinda follow up with that line of thinking. Now some of the ideas that are being bandied about sound more like organic farming by some proponents of sustainable farming.
