abstract:
The most characteristic feature of hydrogels is the ability of binding significant amounts of water. They also include cations, most frequently sodium ones. The aim of the research was to assess the effect of hydrogel Alcosorb AS 400 as medium amendment on the nutritional status of lawn grasses grown in green area (Red Fescue ‘Nimba’, Sheep’s Fescue ‘Noni’, Variousleaf fescue ‘Sawa’, Perennial ryegrass ‘Info’, Kentucky Bluegrass ‘Nandu’). Hydrogel in the doses of 0, 1, 2 and 3 g per dm3 was added to the medium. Increase of hydrogel Alcosorb AS 400 doses caused increase of sodium content in the grass species grown in the experiment. It modified the nitrogen and calcium status of plants.
