  3. The synthesis of the data: establishment a new complex soil qualifying system Six positive and six negative soil parameters were selected from the summer collected soil samples: The maxima of + parameters get +40 „soil value points” The maxima of negative ones ( the heavy metals) get -40 . All measured parameters had been proportioned to these +40, -40 values, after that the soil value points were summed in all cases of samples.
