Nearly All Conventional Food Crops Grown with Fluoride-Laced Water, then Sprayed with More Fluoride

By Ethan A. Huff
The average American today is exposed to a whole lot more fluoride than he or she is probably aware. Conventional produce, it turns out, is one of the most prevalent sources of fluoride exposure besides fluoridated water, as conventional crops are not only irrigated with fluoride-laced water in many cases, but also sprayed with pesticide and herbicide chemicals that have been blended with fluoride, and later processed once again with fluoridated water.

This fact may come as a surprise to many who have bought into the idea that eating more fresh produce is automatically beneficial for health, regardless of how that produce was grown. Thinking that they are doing their bodies a favor, millions of Americans have incorporated conventional fruits and vegetables into their everyday diets, not realizing that the resulting cumulative effect of fluoride exposure from these foods could be harming their health.

Many food crops uptake fluoride chemicals from water, soil

According to the U.S. Centers for Disease Control and Prevention (CDC), nearly 75 percent of the U.S. population is being forcibly medicated with fluoride chemicals via their water supplies. This means that a significant percentage of U.S. crops are also irrigated using this same fluoridated water, particularly in the "Bread Belt" states, many of which are almost entirely fluoridated. (http://www.cdc.gov/fluoridation/statistics/2010stats.htm)

While not all crops uptake fluoride from water in the same amounts, many absorb significant amounts of fluoride through their root systems every time they are watered. Tea plants, for instance, are among the worst when it comes to absorbing fluoride from soil and water, and storing it in their leaves (http://lpi.oregonstate.edu/infocenter/phytochemicals/tea/). Grapes are another crop that tends to accumulate fluoride in high levels as well.

Organic Farming Can Be More Profitable in the Long-Term than Conventional Agriculture

By Jeremy Hance
Organic farming is more profitable and economically secure than conventional farming even over the long-term, according to a new study in Agronomy Journal. Using experimental farm plots, researchers with the University of Minnesota found that organic beat conventional even if organic price premiums (i.e. customers willing to pay more for organic) were to drop as much as 50 percent.

"Doing an economic study like this, it's important to get as complete a picture of the yield variability as we can," explains Timothy Delbridge, lead author of the study and a doctoral student studying agricultural economics at the University of Minnesota. "So, the length of this trial is a big asset. We're pretty confident that the full extent of the yield variability came through in the results."

Conducted over 18 years, the study found that a conventional farm, rotating corn, soy, oat, and alfalfa over 4 years brought in $273, while an organic farm netted $538. Even if the organic premium dropped by half, it would still be more profitable given that the cost of production was lower for organic, since organic farmers would spend nothing on chemicals.

"What we're looking at here are results between an established organic and an established conventional system. This research doesn't take into consideration the issue of the transition itself: how difficult or costly that may be," cautions Delbridge.

Organic Farmers Can Sue Conventional, GMO Farmers whose Pesticides 'Trespass' and Contaminate Their Fields

By Ethan A. Huff
Purveyors of conventional and genetically-modified (GM) crops -- and the pesticides and herbicides that accompany them -- are finally getting a taste of their own legal medicine. Minnesota's Star Tribune has reported that the Minnesota Court of Appeals recently ruled that a large organic farm surrounded by chemical-laden conventional farms can seek damages for lost crops, as well as lost profits, caused by the illegal trespassing of pesticides and herbicides on its property.

Oluf and Debra Johnson's 1,500-acre organic farm in Stearns County, Minn., has repeatedly been contaminated by nearby conventional and GMO farms since the couple started it in the 1990s. A local pesticide cooperative known as Paynesville Farmers Union (PFU), which is near the farm, has been cited at least four times for violating pesticide laws, and inadvertently causing damage to the Johnson's farm.

The first time it was realized that pesticides had drifted onto the Johnson's farm in 1998, PFU apologized, but did not agree to pay for damages. As anyone with an understanding of organic practices knows, even a small bit of contamination can result in having to plow under that season's crops, forget profits, and even lose the ability to grow organic crops in the same field for at least a couple years.

Organic Farming Just as Productive as Conventional, and Better at Building Soil, Rodale Finds

By Tom Philpott
Organic agriculture is a fine luxury for the rich, but it could never feed the world as global population moves to 9 billion.

That's what a lot of powerful people -- including the editors of The Economist -- insist. But the truth could well be the opposite: It might be chemical-intensive agriculture that's the frivolous luxury, and organic that offers us the right technologies in a resource-constrained, ever-warmer near future.

That's the conclusion I draw from the latest data of the Pennsylvania-based Rodale Institute's Farming Systems Trial (FST), which Rodale calls "America's longest running, side-by-side comparison of conventional and organic agriculture." Now, Rodale promotes organic ag, so industrial-minded critics will be tempted to dismiss its data. But that would be wrong -- its test plots have an excellent reputation in the ag research community, and the Institute often collaborates with the USDA's Agricultural Research Service.

Housed on Rodale's 330 acre farm, the FST compares three systems for growing corn and soy, the first two organic and the third conventional: 1) one based on rotating feed crops with perennial forage crops for cows, and fertilizing with manure; 2) another based on rotating grains with cover crops, with fertility coming from nitrogen-fixing legumes; and 3) a system reliant on synthetic fertilizers and pesticides.
