You are correct, some soils have lower quantities of the macro-nutrients (Nitrogen, Phosphorus, Potassium) or an unbalanced pH (as Matt referred to). Plants need a stabilizedpHto help absorb or use those nutrients, via theirrootsystems.

Those macro-nutrients, are the major nutrients corn needs to grow, as well as other plants. Other micro nutrients are needed as well, but in much less quantities. Beans, on the other hand, are a legume plant, therefore fixate nitrogen.

Thosenutrients are more prevalent in some soil types, situations, environments, etc. In other soil types, the loss of these nutrients occurs more rapidly and therefore, need to be replenished on a more frequent basis (sandier soilslose nutrients more readily). pH must stay within the appropriate range as well.

Matt hit the nail on the head. . .while some soils are better suited for large scale farming operations, food plots can have success in poor soil conditions, it just requires more work and a lot of $$$.

Hopefully this helps clearify a few things.
