This study is conducted in order to determine some of the physical and chemical properties of the soils on which 17 species of the spring–flowering Colchicum genus that are natural grown in flora of Turkey. For this purpose 109 soil samples were taken from 36 provinces between 2007–2014. For this objective pH, salinity, lime (CaCO₃), organic matter, available phosphorus (P) and potassium (K) of soil samples were detected. According to the results of the study; all of the taken soil samples were considered within non saline or slightly saline soil class. The soil pH was found to be between 5.06 to 8.77. Highly calcareous soils were also discovered although the amounts of CaCO₃ were generally medium or low in soil samples. More than half of the soils were found very high levels of organic matter while the rest had different contents of organic matters. While 62.3% of the total number of samples contained moderate phosphorus, 12% of them had low phosphorus content. The remaining samples had low phosphorus content. For potassium, these values were 12.9% low, 29.3% medium and 57.8% high.
