Influence of gypsum treatment on extractability of nutrients from soils

Popis výsledku v původním jazyce

In an incubation experiment with 36 soils we tested the influence of application of 3.3 g of CaSO4.2H2O per kg of soil on extractability of nutrients (P, K, Mg, Ca, Mn, B and S). After 134-day incubation of gypsum-treated soils the soils were extracted with water (1:5, w/v), 0.5 M ammonium acetate with NH4F addition (pH 7) and by Mehlich 3 method. An ICP-technique was used for nutrient detection and colorimetry on a SKALAR analyser was employed to determine phosphates and sulphates. The most interestingresults were measured in phosphorus. P concentration was markedly lower in the H2O extract after gypsum treatment, on average by 69% in ICP detection and by 58% in colorimetric detection of phosphates. A significant depression of P concentration was alsomeasured in the acetate extract, but it was considerably lower (11% in ICP detection, 14% in colorimetry). On the contrary, in Mehlich 3 extraction the concentration after gypsum treatment was higher on average by 31% in ICP detection wh
