"Soil Doctors Hit Pay Dirt In Manhattan's Central Park"

"Manhattan's Central Park is surrounded by one of the densest cities on the planet. It's green enough, yet hardly the first place most people would think of as biologically rich.

But a team of scientists gt a big surprise when they recently started digging there.

They were ten soil ecologists — aka dirt doctors. Kelly Ramirez from Colorado State University was among them. "We met on the steps of the natural history museum at 7 a.m. with our collection gear, coolers, and sun block," she recalls."
