The effect of inert media and fertilization levels on nutrition status of green house tomato cv. ‘Maeva F₁’ was investigated. Mean microelement content was: 118.5 mg Fe, 51.7 mg Zn, 269.0 mg Mn and 11.43 mg Cu kg⁻¹ of dry mass of the index parts of the tomato (9–10 leaf form the top). No significant effect of rockwool, expanded clay and polyurethane foam on microelement contents was found in the index parts of the greenhouse tomato, except for zinc whose content was significantly higher in the leaves of the plants grown in rockwool and polyurethane foam than in expanded clay. Fertilization levels did not affect significantly the content of iron, manganese and copper in the index parts, except for zinc whose content lowered at higher fertilization level. High tolerance of the tomato plants to zinc and manganese content in feeding solutions was indicated. No phytotoxicity of zinc nor manganese was found at the content of 2.01 mg Zn and 1.78 mg Mn dm⁻³ of water or feeding solution.

Roses cv. 'Trixx' were grown in 4 different slabs of mineral wool (100 cm length, 15 cm width and 7.5 cm height), which were placed on specially constructed racks in a greenhouse. The cultivation method using bent shoots was used. The studied growth media were: rockwool slabs - Master and Pargro which had a horizontal fibrous structure, Bomat slabs with a homogeneous structure and glasswool Cultilene slabs with a homogeneous structure. The physical properties of mineral wool slabs were obtained from 15 cm long and 15 cm width samples. The samples were taken from slabs before cultivation, and periodically from a greenhouse during the 2.5 year growing period (6, 12, 18, 24 and 30 months after planting). The bulk density increased and total porosity decreased in the Master and Cultilene slabs as early as after six months of cultivation. Other changes in the remaining slabs were not evident until the end of the cultivation stage. The air-water properties depended on the cultivation time and were very different at -4 cm H2O. More stable values of air-water properties were observed at -10 cm H2O. Usually in the beginning of the cultivation period, water content was lower - especially at the -10 to -5 0 cm H2O range of water potential.
