Organic operations tend to be short lived operations. You cannot take nutrients from the soil for many years before production drops off substantially. Weed and pest concerns will become a great problem over the course of a couple seasons. Then there's the marketing. Some are willing to pay extra for "organic," just try to find them!
Unless you have a neighbor with a huge dairy/pig/poltry/operation with a surplus of nutreients and no where to put them, you're going to be in trouble in a couple-three years.
