Nutritional differences between organic vs conventional farming methods

Nutritional differences between organic vs conventional farming methods

Note: This study was taken in 1995 Organic vs Conventional... GMOs are not even listed here to compare with the other two!

"One study that’s often mentioned in the organic vs. conventional debate is the Firman E. Bear report. This report DID NOT look at the nutritional differences between organic and conventionally raised produce, though the popular press has incorrectly portrayed it in this manner for many years. The study, published in a 1948 edition ofProceedings of the Soil Science Society of America (7), examined the mineral composition of vegetables grown in different regions and on different soil types. Part of the more recent confusion may stem from the way the results were presented; i.e., organic and inorganic soil types rather than organic and conventional production methods.

Dr. Bear and his colleagues found that vegetables grown on heavy soils in the Ohio Valley had a greater mineral content than produce grown on sandy Coastal Plain soils near the East Coast. Interestingly, fertilizer rates on farms in the coastal-plain states were much higher in contrast to fertilizer rates used on farms in east north-central states. Clover sods and manures were more prevalent in the east north-central region. These results are important in themselves because they show that soil type (and quite likely differences in clay mineralogy, soil organic matter, and biological soil activity) affect the mineral composition of foods grown on them. In general, they found that trace element and mineral content increases from south to north, and from east to west. Overall, mineral composition is affected by geography, climate, and fertilizing practices".

I agree the issue of organic vs. conventional is complex as to why the produce does typically have higher nutritional content. Soil quality, including depletion from overfarming, is just as important. Organic and biodynamic practices do more to replenish soil, as they rely on it more heavily than conventional farming and its petrochemical fertilizers and pesticides. It is all related.
