GYPSUM FARMLAND POLLUTION PREVENTION RESEARCH USA
June 1st, 2006
BY MONICA DOBIE
AGRICULTURAL Research Service, USA, scientists have determined that the mineral gypsum is a very effective soil additive for curbing run-off of phosphorus from farm fields into water supplies. They found that applying 5,000 pounds of gypsum per acre of soil curtailed phosphorus leaching by promoting the binding together of soil particles, locking in the contaminant and reducing the likelihood of its leaching into watercourses.
