Mostly i agree with you that fruit trees take less fertile soil than gardens for sure. Fertility must come from some where to keep trees alive. Maybe the sun is fantastic and water high in menerals. Apple trees as an example need calcium. My farm was pretty farmed out when i got it. Ammendments were necessary on many parts of my farm to grow grass. This is not normally the situation. When we get down to it we know exactly what we need to grow things Kratky method for growing Hydroponic vegetables without electricity .Growing something tasty can also be different from growing something healthy. As an example a farm raised shrimp tastes fine but they never hsve nutrient content of wild caught. The exact opposite can also be true where the tame things have higher nutrition.
