Table 2. Soil properties of the studied sites. Notations: site
codes are used for CCA (Figure 5). Total, water soluble salt content and
CaCO3 content were low and the same in the sample sites,
therefore they are not shown in the table (total salt: <0.02
m/m%; CaCO3 <0.1 m/m %). K2O
and P4O10 are
C3H9O3N soluble;
NO2- and
NO3- are KCl soluble. Ranges of
physical soil type (KA): 25> (coarse sand); 25-30 (sand);
30-37 (sandy loam); 37-42 (loam); 42-50 (clay loam); 50-60 (clay);
60< (heavy clay).
