    • Abstract:
      The article examines the influence of tropical forest conversion to grazed cattle pasture in the Brazil's Amazon forest on different forms of nitrogen and phosphorus in soil solution and stream water. It compares two pairs of watersheds containing streams that drained land in either forest or pasture at Fazenda Nova Vida, a cattle ranch in Rondonia. Results indicate forest soil solution having higher concentrations of nitrate than pasture, but with same concentrations of ammonium and phosphate.
