- Abstract
Fertilizing turfgrass helps keep the turf green in good aesthetic condition. Regular fertilisation makes turfgrass more resistant to adverse weather conditions, for example droughts, and gives it the characteristic dark green colour. Fertilisers also protect turfgrass from moss and various diseases. A visual assessment was carried out (general aspect, turf area, leaf colour and structure), in addition to which selected vegetation indices and content of minerals were evaluated. Conducted at the Experimental Station of the University of Agriculture in Krakow, Poland, the research was carried out to assess the functional value of turfgrasses. An amino acid product sprayed at a dose of 2.0 dm³·ha-1 and iron chelate at a dose of 130 g Fe·ha-1 constituted experimental factors. The visual assessment of turfgrass characteristics was made on a 9-point scale. The mineral content of the plant material was also determined. During the growing period, the grass was mowed to a height of 6 cm. The combination of both products significantly increased the quality of turfgrass. The turfgrass in the plots treated with amino acids and Fe chelate applied together had the highest aesthetic and functional values. Satisfactory results were also obtained in plots where the amino acid product was applied on its own.
