Demand for organic soybeans is outstripping supply but farmers are having a difficult time increasing supply due to a shortage of seed and biotech contaminates from their non-organic neighbors, The Wall Street Journal reported. Currently 91% of USA soybeans are grown from genetically modified seed which is banned under the USDA Organic protocol. The premium for organic beans currently runs 15 to 20% above the $10 per bushel price of conventional soybeans. This has sent organic soybean users in two directions. One, to substitute non-organic beans for organic beans, and two, to buy their beans from China. Currently, China is the world’s largest grower of organic soybeans. Organic acreage there has increased from 40,000 hectares in 2002 to 3.4 million acres in 2006. Recently Dean Foods introduced a non-organic line of their Silk soymilk that is 30 cents a half gallon cheaper than their Certified Organic version. Of course, if consumers really want to save money, old-fashioned milk from cows is 50 cents a half gallon cheaper than the cheapest soybean milk.
