| چکیده انگلیسی مقاله |
In the present study, some important physical and chemical soil characteristics of orchid (Dactylorhiza spp.) growing areas in Northeastern Turkey (Vercenek Mountains) were determined. A total of 5 soil samples from different Dactylorhiza spp. growing areas within the border of Vercenek Mountains were collected and analyzed. The main parameters searched to determine soil characteristics were water retention characteristics, pore size distribution, bulk density, electrical conductivity (EC), pH, organic matter, carbonates and microelements. The water retained at the low tensions (<0.03 MPa) in Dactylorhiza spp. growing areas soils were between 27.33-43.34 based on % of volume. The soil samples showed 24.73% and 17.44% the highest and lowest water retention capacity between 0.03-1.5 MPa, respectively. Among the samples bulk density were 0.33 and 1.01 g.cm3, respectively. EC, pH and organic matter values of samples varied from 0.36-1.77 dS.m-1, 6.02 to 7.19 and 2.44-16.18%, respectively. |
