Properties of the soils of Bellevalia (Bellevalia spp.) species naturel grown in flora of Turkey

This study is conducted in order to determine some properties of the soils on which different species of Bellevalia genus that are natural grown in flora of Turkey. For this purpose 41 soil samples were taken from 19 provinces between 2010-2014. Texture, pH, salinity, CaCO3, organic matter, available phosphorus, exchangeable potassium, calcium, magnesium and available iron, manganese, zinc, copper of soil samples were analyzed. According to the results of the study; all of the taken soil samples were considered within non saline or slightly saline soil class. In the evaluation, it was observed that the plants preferred the loamy texture soils. Mostly the soil samples within the observed area were determined to have light alkaline characteristics. Although the amount of CaCO3 was generally low and medium in soil samples, highly calcareous soils were also discovered. It has been determined that soil samples had high or very high levels organic matters substantially. The available phosphorus values of the soils were ranged between 1-82 mg kg-1. The exchangeable potassium, calcium and magnesium contents of soils were found on average 1.00, 38.65 and 3.80 me 100 g-1 respectively, and almost all were at medium or high levels. In terms of micro-elements, copper and manganese were found to be sufficient in all soils, while zinc had a deficiency of 39% and iron 22%
