Differences in available phosphorus evaluated by soil tests in relation to detection by colorimetric and ICP-AES techniques

Popis výsledku v původním jazyce

Differences in the evaluation of soil phosphorus status by three soil tests (Mehlich 3, extraction with NH4-acetate and water extraction) were tested on 63 agricultural soils with different agrochemical characteristics. The median of P-supply in soils determined by soil tests was considerably different. Compared to the colorimetric detection of water extraction of soils the median of the NH4-acetate test showed 2.2 times higher values and in Mehlich 3 test the values were 34.8 times higher. The largestdifference between the end-point analytical P-determination was observed in the soil test of water extraction. The median of the values determined by ICP-AES was higher by 47%. In NH4-acetate soil test the median of the measured phosphorus was higher by12% and in Mehlich 3 by 7%. Differences of P-concentrations determined by colorimetry and by ICP-AES increased as P-supply in soils decreased. When the supply of ?available? phosphorus in soil is given, it is always necessary to specify t
