In order to achieve the established objectives of research,
both laboratory tests and field investigation were conducted.
The research work aimed at showing the impact of different
hydrogel concentrations and investigation of its capacity
to retain water by soil water absorption by seedlings was
conducted in the laboratory as well as in the greenhouse.
The ability of soil to retain water was recognized by means
of moisture measurement of soil with the use of the Time
Domain Reflectometry (TDR) method and through the implementation
of pF curves using the dust-blocks Eijkelkamp
and Soil Moisture Ltd pressure chambers.
