Chemical and Physical Characteristics in Uncultivated Soils with Different Lithology in Semiarid Mediterranean Clima

Table 3

Average values in soils from investigated areas for pH, electrical conductivity, CEC, macronutrients (, micronutrients (, and organic matter (OM). Standard deviation, minimum, and maximum are also presented. Identical letters in the same column denote no statistical difference in average values according to t-test with alpha coefficient 5%.
