In the Bible it talks about letting the soil rest after so many crops, but the way they raised crops was even less damaging than our industrialized agriculture.. as I've gone over on my podcast a few times tilling, non-organic feeding and pest removal, and monocropping on thousands or millions of acres can be very damaging to the top soil. There has been quite a few studies to show that there are around 50-60 crops left in America and maybe less than 40 in the UK, to make it worse vegans want more places to be taken over with vegetable farms including wiping out beef and chicken farms which would damage the top soil even more! Here's some links to studies:
