Effect of depth of placement of the hydrogel and the type of soil cover on the initial growth and development of lawn grasses

Abstract

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 dynamics of lawns emergence.

Celem pracy było zbadanie wpływu superabsorbentu Aqua–gel P4 na dynamikę 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.
