| heal.abstract |
For 15 soils with widely different extractability of phosphorus (P) two newly introduced digestion techniques for determining total P (Pt) were compared with the standard perchloric acid digestion procedure. The two digestion techniques were: (1) concentrated H2SO4 plus 30 % H2O2 at 360 °C, (2) concentrated HCl plus concentrated HNO3 in the ratio 3:1 (aqua regia) at 140 °C. Almost equal amounts of Pt were extracted by the two methods (mean = 188.7 mg kg-1 for H2SO4/H2O2 and 188.4 mg kg-1 for aqua regia) which were slightly higher than the standard method (mean = 183.8 mg kg-1). However, there is no statistical difference among the three digestion methods, suggesting that the tested methods should be useful for estimating Pt in soils with high content of organic C, eliminating the danger of explosion when hot concentrated HClO4 is used. |
