Determination of soil microbial diversity
The new molecular diversity methods - DGGE = Denaturing Gradient Gelelectrophoresis - TGGE = Temperature Gradient Gelelectrophoresis - TTGE= Temporal Temperature Gradient gelelectrophoresis - SSCP= Single Strand Conformational Polymorphism - RISA, ARISA (Automated) Ribosomal Intergenic Spacer Analysis - Community ARDRA, Community ITS RFLP - T-RFLP= Terminal Restriction Fragment Length Polymorphism

Variability of the size of the ITS region in distinct fungal groups
Multiplication of the ITS region and electrophoresis of the PCR products PCR was carried out in a final volume of 50 μl containing 5 μl of Taq polymerase 10 x puffer, 1. 6 m. M Mg. Cl 2, 200 μM for each of the d. NTPs, 10 p. M primers, 5 μl of template DNA (app. 100 ng) in distilled water and 1 U Taq DNA polymerase (Fermentas). The PCR product was visualized with gelelectophoresis, and the DNA fragments in the gels were stained with SYBR Green and analyzed under UV light. Primers used in bacteria: For the amplification of the bacterial ITS region, the Eub-ITSF as forward and Eub-ITSR as reverse primers were used. Eub-ITSF: 5’-GTCGTAACAAGGTAGCCGTA-3’ Eub-ITSR: 5’- GCCAAGGCATCCACC-3’ Primers used in fungi: the best is the ITS 5 –forward ITS 4 -reverse combination.

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: Trypsin-like protease +40 Palmitoylesterase (PE) +40 Bacterial species richness (SR) +40 Humus +40 Phosphorus, mobile (P mobile ) +40 Potassium, mobile (K mobile ) +40 Zinc -40 Copper -40 Manganese -40 Nickel -40 Cadmium -40 Lead -40 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.
