Description
:
|
Available phosphorus measured in soil after extraction with 0.5 M NaHCO3 and measurement by continuous flow analysis (CFA) using high resolution colorimetry and photometric detection. Ammonium heptamolybdate and potassium antimony(III) oxide tartrate react in an acidic medium with dialysed and diluted solutions of phosphate to form an antimony-phospho-molybdate complex. This complex is reduced to an intensely blue-coloured complex by L(+)ascorbic acid. The complex is measured at 880 nm. |
