ABSTRACT
Available elements in soils were extracted with ammonium sulfate [(NH4)2SO4] 0.1 M and total element was measured after acid digestion (nitric acid: hydrogen peroxide), both in soils and plants.
Arsenic was analyzed by HG-AFS in soils, plants and leachates and P was measured spectrophotometrically in soils and by ion chromatography in plants.
