Effects of Soil Conditioners on Lawn Grass Growth in Different Year Seasons

Abstract

The field experiment was conducted in Poland between 2013 and 2015. The research was carried out in the split plot design with three replications. The following grass species were used in the experiment (factor B): Lolium perenne, Festuca rubra and Poa pratensis. Another experimental factor tested in the research was soil conditioners (factor A) as Substral (S), Humus Active Papka (HAP), Eko-Użyźniacz (EU), UGmax (UG). In each year of the experiment, among other things, grass growth, i.e. its slow rate of growth, was assessed. It was based on measurements of the height of plants before harvest. A 9-point scale was used. This assessment was conducted in three seasons (spring, summer, autumn). In all seasons red fescue had the most desirable intensity of growth (the slowest) and permanent ryegrass the fastest, both determined as an average effect of all soil conditioners. Of the applied soil conditioners, lawns treated with Humus Active Papka, grew the most slowly, taken as an average for all grass species and for all seasons. Of all grass species tested in the experiment red fescue had the smallest variation of growth intensity during the research.

The effect of soil and climatic conditions on the distribution of nutrients in Actinidia arguta leaves

“…The study of the ecology of nutrients is now becoming increasingly important, since it is known that in different soils mineral compounds are almost never found in such quantities and in such balanced proportions that would be optimal for growth and development of plants (Zaimenko, 2008;Jankowski et al, 2018aJankowski et al, , 2018bLoza et al, 2018;Lykholat et al, 2018). The latter always compensate for the negative effects of the environmental stress factors by triggering adaptive changes in the plant nutrition and other physiological processes (Zaimenko, 2019).…”
