In 1999, scientists dropped 45 tons of wollastonite over a 29-acre New Hampshire watershed to replace calcium lost to acid rain; by 2013, it was exporting 30 times more inorganic nitrogen than nearby watersheds
- In October and November 1999, researchers spread about 45 short tons (40 metric tonnes) of a calcium-rich mineral over a 29-acre (11.8-hectare) catchment in New Hampshire.
- The treatment was meant to replace important soil nutrients that had been washed away by decades of industrial pollution.
