Disappointing biotech crops.
One of the selling points for many genetically engineered crops has been that farmers will need fewer inputs and therefore have higher returns per acre. However, two recently released studies indicate that this may not necessarily be the case.
Researchers at the University of Arkansas found that net income from land planted with Bt cotton was less than land planted with conventional cotton by an average of $25 per acre in 1997, based on observations in three Arkansas counties.
A second study released by American Cyanamid, a U.S. multi-national agrochemical company and one of Monsanto's main competitors, found that farmers could experience yield losses up to $43 per acre when planting Monsanto's Roundup Ready soybeans.
