As Baltimore officials begin to tackle the polluted runoff fouling the harbor and the Chesapeake Bay, they are turning to a technique long used by farmers. At Yorkwood Elementary School in Northeast Baltimore this week, a tractor plowed deep into a half-acre patch of playground that until recently had been covered in asphalt. The farm vehic earth le towed a claw-like contraption with long curved blades that slice far into the packed. “That’s what Freddy Krueger would have done if he was trained as an agricultural engineer,” said Stuart Schwartz, a senior scientist with the Center for Urban Environmental Research and Education.
