The study focused on the influence of hydrogel on seedlings. Hydrogel is a good absorbent
of macromolecule compound that can effectively bind water. The possibility of hydrogel
to retain water is very important in the case of poor soils, especially when seedlings are
growing in unfavorable drought conditions. From a theoretical point of view, hydrogel and
its positive influence on survival and growth of seedlings is proved, but the question arises
how it may affect, for instance, soil water increasing potential, reduction of mycorrhizas
or pollution absorption. The investigation was conducted on areas difficult for afforestation,
such as agricultural, after-military, post-industrial and post-drainage peat-bogs. The
influence of hydrogel on soil moisture, pF curve, water consumption by seedlings was also
observed under laboratory conditions and in greenhouse. Main objectives of the present
study include detection of effects of hydrogel application on survival and growth processes
of pine (Pinus sylvestris) seedlings.
