Use of lawn grass mixtures with iron sulphate for the renovation of lawn with moss
Journal Title: Journal of Research and Applications in Agricultural Engineering (ISSN 1642-686X) - Year 2018, Vol 63, Issue 3
Abstract
The experiment was established on the shaded area of the lawn occupied by mosses (Bryophyta sp.) around the Biocentrum building of the University of Life Sciences in Poznań. Lawns with moss were selected for the study, with an average share of at least 55%. Three seed mixtures present on the market in the commercial offer of seed companies were tested in the experiment. Mixture G contained grass seeds coated with a monohydrate form of iron sulphate (FeSO4 H2O) in the amount of 31.92 mg of Fe, while in the mixture R the heptahydrate form (FeSO4 7H2O) in the amount of 1.5 mg of Fe per 1 gram of kernels was used. The seeds of the H control mixture were not coated with iron sulphate. The best effects of moss control in the lawn, among the tested lawn mixtures whose seeds were coated with iron sulphate were obtained after the use of mixture G. This application led to brisk dying and eradication of mosses yet the germination rate of kernels was slower than in the case of other mixtures and so was the pace of sodding in the areas under renovation.. In the case of the lawn mixture R, no toxic effects on mosses and their permanent control were found. Lack of satisfactory effects in moss control was caused by the use of too low concentration of iron sulphate, which coated the seeds. The most effective moss control and surface coverage with new grass seedlings was obtained using the traditional method based on applying Nawomix fertilizer to control mosses, raking dead moss and sowing seeds with lawn mixture H following seeds covering by soil.
