All of us are trying to acomplish the same thing, and soils that are high in active carbon greatly improve the effient uptake of nutrients. I'm impressed that no one said anything about the "organic molecules" of my previous post. Especially since ammonia, nitrite, and nitrate have no carbon molecules in them. Under the traditional definition of an organic molecule, they are not organic compounds, but I think you've demonstrated that there is more to ecological processes than just adding fertilizer, effective biocatalyst are important factors in the life processes, especially when they effect banana growth!
Best wishes! Healthy disscussions like this are part of (or should be) part of the scientific process.
