In order to feed the predicted population apex of 9 billion people by 2050, we must increase our ag yield by 20 to 30 percent, said Becky Timmons, Alltech’s global director of applications research and quality assurance, at the closing session of the 30th Alltech Symposium. We have two options: We can spread out on more land, which is not possible, or get better yield off the land we have. How can bees and microbes help? Without microbes, there would be no plants or animals. Their biodiversity is significant, and their roles are crucial.
