A few small orange flags stuck in the dirt are the only markers that distinguish Kwesi Joseph’s kale and collard plantings from the rows of other lush vegetables at the Hands and Heart Community Garden on New Lots Avenue in East New York. But Joseph, an urban gardens specialist for the Cornell Cooperative Extension, is conducting a low-tech and audacious experiment with those vegetables. His thesis is simple – crushed basalt rock mixed with soil and compost in this Brooklyn garden will both capture more carbon from the air and also help plants grow bigger, thus increasing the potential yield of fruits and vegetables. “If urban gardens can assist in sequestering carbon, why not?” Joseph said.
