Measurement of ammonium in 1 M KCl extract |
|
Description
:
|
Extraction of ammonium-N by 1 M KCl followed by measurement by continuous flow analysis (CFA) using high resolution colorimetry and photometric detection. During the CFA measurements, samples were dialyzed on-line and NH4-N was determined by the Berthelot reaction. Ammonia is buffered and chlorinated to monochloramine which reacts with salicylate to 5-aminosalicylate. After oxidation and oxidative coupling a green coloured complex is formed. The absorption of the formed complex is measured at 660 nm. |

Measurement of nitrate in 1 M KCl extract |
|
Description
:
|
Extraction of nitrate-N by 1 M KCl followed by measurement by continuous flow analysis (CFA) using high resolution colorimetry and photometric detection. After on-line dialysis, the sample is buffered at pH 8.2 and is passed through a column containing granulated copper-cadmium to reduce the nitrate to nitrite, which is determined by diazotizing with sulfanilamide and coupling with N-(1-naphthyl)ethylenediamine dihydrochloride to form a highly coloured azo dye which is measured at 540 nm. The determination of NO3-N concentrations by cadmium reduction usually includes a small amount of originally present nitrite-N (NO2-N), which was below the detection limits and hence considered negligible. |

Extraction of ammonium-N by 1 M KCl followed by measurement by continuous flow analysis (CFA) using high resolution colorimetry and photometric detection. During the CFA measurements, samples were dialyzed on-line and NH4-N was determined by the Berthelot reaction. Ammonia is buffered and chlorinated to monochloramine which reacts with salicylate to 5-aminosalicylate. After oxidation and oxidative coupling a green coloured complex is formed. The absorption of the formed complex is measured at 660 nm. |

Extraction of nitrate-N by 1 M KCl followed by measurement by continuous flow analysis (CFA) using high resolution colorimetry and photometric detection. After on-line dialysis, the sample is buffered at pH 8.2 and is passed through a column containing granulated copper-cadmium to reduce the nitrate to nitrite, which is determined by diazotizing with sulfanilamide and coupling with N-(1-naphthyl)ethylenediamine dihydrochloride to form a highly coloured azo dye which is measured at 540 nm. The determination of NO3-N concentrations by cadmium reduction usually includes a small amount of originally present nitrite-N (NO2-N), which was below the detection limits and hence considered negligible. |

Measurement of effective CEC and exchangeable cations |
|
Description
:
|
Excheangeable cations K, Na, Mg, Ca, Al, Fe, Mn are measured by ICP-OES after extraction of soil samples with 1 M NH4NO3. Effectice CEC is calculated as sum of cations. |
