“…The results of a joint institutional project in Czechia, Hungary, Poland and the Netherlands on the calibration of the 0.01M CaCl 2 soil testing procedure for Mg are presented by Loch et al (1998). With the relatively weak extractant, 0.01M CaCl 2 , somewhat lower quantities of Mg were extracted from the soil samples compared to the extraction solutions used in Poland (0.0125M CaCl 2 ), in Hungary (1M KCl) and in the Netherlands (0.5M NaCl).…”

“…In most comparative studies, the results of the two extraction procedures are related by using statistical techniques like (multiple) linear regression. To increase the explained variance of the relationships, soil characteristics like the soil type, organic matter, clay, and carbonate contents are also arbitrarily included (Baier & Baierova 1981;Matejovic & Durackova 1994;Mamo et al 1996;Loch et al 1998). We can https://doi.org/10.17221/92/2019-SWR also conclude that not only the extraction method, but also soil properties like the carbonate content, have an effect on the evaluation of the magnesium measurements.…”

Magnesium is one of the most important nutrient elements. Soils are tested for magnesium in many countries with several extractants. Each country has its own validated methods, best-suited for its soils. The current study was designed to compare different magnesium content measuring methods with 80 Hungarian samples. The magnesium content was determined by the potassium chloride (1 M KCl 1:10), Mehlich 3 and CoHex (cobalt hexamine trichloride) methods. The maximum, mean and median values resulting from all the Mg determination methods showed the following order of measured magnitude: KCl < CoHex < M3.

More exact information on soil nutrient management is crucial due to environmental protection, nature conservation, decreasing sources for mining, general precaution, etc. Soil magnesium (Mg) analytical methods of potassium chloride (KCl), Mehlich 3 (M3), water (WA) and cobalt hexamine (CoHex) extractions are compared with an elemental analysis and X-ray fluorescence (XRF) analysis. The ratio of the available to the total Mg content was calculated and compared on the whole dataset. The results showed that the linear regressions between all the pairs of Mg content measurement methods were significant. The linear relationship between the KCl and CoHex methods has the highest determination coefficient (R2 = 0.96), followed by WA–M3 (R2 = 0.68), M3–CoHex (R2 = 0.66) and M3–KCl (R2 = 0.60). The M3 solution demonstrated a greater capacity for extracting Mg from the soil. The second part is the analysis of the influence of CaCO3, pH, soil texture and clay content on the measurable magnesium content of soils. It was established that the extraction methods, the soil and the classification method of the soil properties affect the evaluation. These results may help through the nutrient replenishment and the melioration of soils. These results can help the examination of mineral nutrients, especially the Mg uptake.
