>vegetables "as one proceeds from north to south and and from east to west in
>the United States." Samples of cabbage, lettuce, snapbean, spinach and
>tomato were obtained from commercial fields of these crops and analysed for
>mineral composition. These highest and lowest values have been
>misrepresented as vegetables grown organically and inorganically,
>respectively, in various organic farming and health food newsletters which

>The authors discussed the influence of soil type, fertilizer practice, and
>climate on the observed differences in mineral composition. The study only
>provides a general survey of their possible influence and did not compare
>synthetic fertililzer and organic practices."
