Science & Tech Spotlight: Engineered Biofertilizers

Print
WHY THIS MATTERS
Chemical fertilizers account for up to 45 percent of input costs
for some crops. Engineered biofertilizers may reduce these
costs and increase crop yields.
KEY TAKEAWAYS
» Engineered biofertilizers are made of microbes and other
organic materials that improve nutrient supply in soil.
» The lack of a clear definition for biofertilizers leads to
uncertainty about whether existing regulations apply.
» Current regulations may also not be equipped for
genetically engineered microbes, which may hamper
U.S. competitiveness.
