The aim of this work to determine the effect of superabsorbent Aqua–Gel P4 on the
dynamics of lawns emergence. The experiment was established in 2007. The studies were
carried out on the base of two lawn experiments. The first experience was a monoculture lawn
where in pure sown four species of lawn grasses were studied. In the second experiment four
designed mixtures of the same grass species were used. At the beginning of the study (2007)
after 15 and 30 days, evaluating of the grasses emergence was done. The type of used soil
cover (cultivated soil or garden peat) did not cause significant variation in the emergence of
both lawn grasses sown in pure stand and in mixtures. With the increasing of the depth of
hydrogel placement (5, 10, 15 cm) in soil, the emergence value of the lawn grasses sown in
both as pure stand and in mixtures has worsThe aim of this work to determine the effect of superabsorbent Aqua–Gel P4 on the

wschodów traw w zakładanych trawnikach. Doświadczenie założono w 2007 roku i było ono
prowadzone do 2009 roku. Badania były realizowane na podstawie dwóch doświadczeń
trawnikowych. Pierwsze doświadczenie stanowił trawnik monokulturowy gdzie w siewie czystym
badano cztery gatunki traw gazonowych. W drugim doświadczeniu wykorzystano cztery
zaprojektowane mieszanki tych samych gatunków traw. W początkowym okresie prowadzenia
doświadczenia (2007) po 15 i 30 dniach dokonano oceny wschodów traw. Rodzaj
zastosowanej okrywy glebowej (gleba uprawna, torf ogrodniczy) nie powodował istotnego
zróżnicowania we wschodach zarówno traw gazonowych wysianych w siewie czystym jak
i w mieszankach. W miarę zwiększania głębokości umieszczenia hydrożelu (5; 10; 15 cm)
w podłożu glebowym wschody traw gazonowych wysianych zarówno w siewie czystym, jak
i mieszankach uległy pogorszeniu.
