They do it, and you learn a lot about 'ins and out' or 'vagones y barrigas', because each one cultivates differently.

One overall consequence is soil acidification from rain runoff, I am using contour-building to correct over time, but the trees do this naturally on slopes in what is called 'fish scaling'.

Got it. One issue we have in Brazil, on land like that, is that people remove the native trees and well... we know the result, landslides. Luckly we only have a tiny part of our land kinda sloping, where we have rain runoff.
