*3.5. Soil Chemical Properties*

The effects of fertilizer treatments on soil chemical properties are shown in Tables 8–10 and the relationship between the parameters, localities, and fertilizer treatments are shown in Figure 3. The value of pH was not affected by any treatment in Ivanovice (Chernozem) and Lukavec (Cambisol). On the other hand, the application of mineral fertilizers significantly decreased the soil pH value in Caslav (Phaeozem). Application of all fertilizers significantly increased the Nt (%) and Cox(%) in all localities. The same pattern can be seen in the case of P (mg kg−1) and K (mg kg−1). Only in Lukavec, we did not record any differences in P and K concentrations between the control, FYM+N1, and FYM+N2 treatments. The concentration of Ca (mg kg−1) was not affected by any treatment, except for low, but significant differences in Caslav (Control and FYM+NPK treatments). On the other hand, the Mg (mg kg−1) content varied significantly in Ivanovice and Caslav, while no fluctuation was recorded in any fertilizer treatment in Lukavec.
