Abstract
Lawns play an important role in the urban landscape and are good indicators of the environment conditions. In the near road areas they are however exposed to the drought or salinity. Therefore, diverse agrotechnical treatments are applied in order to make the conditions more suitable for vegetation. One of them may be incorporation the hydrogel to soil. These synthetic polymers can absorb huge amount of water and thanks to that are able to decrease the drought stress in plants. Their application is more cost-effective that irrigation. However, too high concentration of ions in soil may decrease efficacy of hydrogel, since it can absorb water and cations as well. The aim of the study was therefore the assessment of the hydrogels efficacy under turf grasses cultivated in the saline soil. The experience was conducted for three months in a controlled green house conditions. The efficacy of hydrogel amendment was measured by the grass reactions (germination, turfs height and condition) to the three levels of salinity. The results allowed concluding that the salinity decreased the germination, height and condition of tested grasses independent on hydrogel addition.
