First, I think organic vegetables taste better, and there is mounting evidence to support that claim. In a recent study, when rats were given the choice of eating biscuits made with organic, versus conventionally grown wheat, they ate substantially more of the organic biscuits.
Second, many studies have shown that produce grown organically, has a higher percentage of vitamins and phytochemicals. Organically grown produce can contain as much as 40 percent more antioxidants than conventionally grown produce.
Third, growing organic, vegetable container gardens is less expensive and less work. According to Pete Bottomley, of Coast of Maine, makers of organic garden products, until about five years organics were more expensive. Now it is actually cheaper to do organic vegetable gardening.
