Adsorption/desorption of organic anions in Brazilian Oxisols

Organic anions affect solute mobility in soils. This study evaluated citrate and oxalate adsorption (0 to 4 mmol L(-1), soil-solution 1:100, pH 5.5, ionic strength 30 mmol L(-1) as NaCl, 72-h reaction) and desorption (pH 5.5, 30-mmol L(-1) NaCl, 72 h) on A- and B-horizon samples of two Brazilian Oxi...
