In 2006, a field trial was established in two localities, Lednice and Starec, with two model plants, Acer pseudoplatanus and Quercus robur. TerraCottem, Agrosil LR and Hydrogel were tested as soil conditioners. Four variants (each of the conditioners and control) were tested in 3 replications. Several physiological characteristics were followed during the growing season using special equipments, viz. Porometer AP 4 (stomatal conductivity), SunScan AT (photosynthetically active radiation) and Chlorophyllmeter CCM 200 (chlorophyll content index). Morphological characteristics (i.e. length of shoots and dry mass of leafs) were measured to the end of the growing season. The best results were obtained with the soil conditioner Hydrogel. The soil conditioners showed a significant effect on both morphological and physiological characteristics of the experimental plants. Soil conditioners eliminated the influence of abiotic stressors on both tree species.
