Wait...What? said:so naturally occurring mineral compounds are not organic in your book then? why not?
Well first we need to look at what real soil is and how it became soil.
An ideal normal soil is 50% parent material (well explain that in a moment), 25'ish% air, 25'ish% water and 5% O.M. (organic matter).
Parent material is made from igneous, metamorphic or sedimentary rock. Igneous rock is cooled magma without crystallization (I.E it cooled underground), metamorphic rock is cooled magma with crstallization (I.E it cooled above ground). Finally, sedimentary rock is exactly what it sounds like, sediment. It is sediment that had settled from generally sea beds of water millions of years ago and has hardened to form rock.
I will make the point that everything on this plant can be viewed as organic. Petroleum, plastics, arsenic and many other undesirable products for our planet.
How our soil's got this parent material in them (carrying these minerals you speak of) was through and/or heat, cold, wind and rain. This process took thousands of years and developed with the ecosystem that surrounded it. Now man strip mines these minerals and processes them through electro-stasis and other techniques. This creates a very concentrated form that would not occur in nature, therefor many organisms cannot tolerate the concentrations. The natural earth is a buffering agent against these minerals. Organic farming is about using bacteria and fungi to your advantage and have organic matter broken down by these microbes.
The processing and mining of these minerals also produces a great amount of waste that is damaging to our environment.
This is one of the main underlying differences between hydroponics and organics. Hydroponics have chelated and plant-available minerals that do not need to be broken down for uptake, man has already done this. Organics is the process of breaking down carbonaceous or nitroceous materials that then make nutrients available for plants. Organics does this in a slow way, so that there is balance in the soil. Conventional agriculture dumps synthetic nutrients into fields and destroys the soil food web. While it is true that many microbes can handle a certain degree of inorganic metal salts, it is not advantageous to an organic style of farming.
Was that a sufficient answer for you?
