This study compared Mehlich II (MII) and Mehlich III (MIII) extractants to determine available phosphorus, potassium, magnesium and calcium in Czech agricultural soils. A total of 2799 agricultural soils were collected for the study (311 light soils, 1889 medium soils, 599 heavy soils, 369 soils with carbonate content higher than 5%). The soil samples represented all major soil types, climatic regions and proportion of agronomic cultures in the Czech Republic.
