A: Your question is a bit broad, so I’m going to address how effective GM plants are in bioremediation. Genetic engineering techniques are very useful in helping with bioremediation. For example, certain plants have been used to help decontaminate polluted soils. The plants can absorb certain pollutants through their roots, and transport them to the above ground parts of the plants, which can then be harvested and disposed of properly. Using plants to clean up contaminated soils is... Continue Reading
Q: Do you think it would be possible to grow GM crops in a large scale contained environment?. This way, it would prevent GM crops from unintentionally spreading out of GM cultures and thus lower the risk of causing important modification to the...

A: First, thank you for an interesting question. The simple answer to your question is yes. Let me amplify though on some of the points to which I think you are alluding. First, growth of any experimental transgenic plant material in an outside environment is not a decision investigators can make by themselves. Outside growth requires that a permit be issued by the U.S. Department of Agriculture. This agency examines the gene inserted and its probable function and then makes a... Continue Reading

A: When it comes to keeping our operation sustainable GE crops can play an important role. Herbicide resistance traits aren't a requirement for no-till farming, but we find the ability to select from a wider range of herbicides in a given crop allows for more flexibility in our weed management program as we transition our farm into more no-till acres. It's nice to have options like this at hand when tillage is no longer a method used for weed control. Two of the best... Continue Reading

A: Will Rogers is credited with the quote: "The farmer has to be an optimist or he wouldn't still be a farmer." Optimistically, each winter we review our harvest data comparing our crop yield by variety to our cost of production for that crop that season, in consideration of the type of growing season we had, in order to decide what seeds to purchase for the coming season. Since 1998, we have been growing both GM and non-GM corn and soybeans. (We don’t actually... Continue Reading

A: There are currently no potatoes sold in the United States that are genetically modified. In 1995, NatureMark introduced NewLeaf potatoes, with resistance to the Colorado potato beetle, and subsequent generations with resistance to potato leaf roll virus (PLRV), and potato virus Y (PVY). The potatoes were withdrawn from the market in 2001. More recently, the J.R. Simplot Company received USDA approval for Innate genetically modified potatoes. These potatoes — available in Russet...
