Sažetak Urban parks play an important role in the ecology of human habitats because they filter the air, produce oxygen and provide shelters and habitats for many species, especially birds. They also represent green oases where people affected by stress or overwork may find a place to rest. Urban parks provide a variety of recreational activities for city residents. The aim of this study is to determine the content of macronutrients (nitrogen, phosphorus and potassium) in grass leaves in the urban parks of public areas in order to recommend optimal lawn fertilization. In addition, nutritional grass leaves statuses as well as analyses were made to determine the amount of macronutrients (N, P, K). Within recreational sport public buildings of the City of Zagreb were selected Recreational Sports Centre (RSC) Jarun and Bundek Park facilities as large green areas that are along with Maksimir Park the “lungs” of the city. Grass leaves and soil sampling were carried out on both lawns three times during the growing season. The content of nitrogen in grass leaves of both lawns is within the limits suggested by current literature whilst there was an determined lack of potassium and especially phosphorus. The determined average value of nutrients in the grass leaves during the vegetation period for Jarun were 3.14% N, 0.31% P and 2.78% K, and for Bundek 3.24% N, 0.41% P and 3.17% K. In general, the results show a slightly higher nutrient value of lawn in the Bundek Park compared to Jarun. On the study sites the largest share of grasses belongs Lolium perenne L. with 70%, Festuca rubra Huds. with 20% and 10% belongs to other plant species. Chemical properties of investigated soils show that the soil on RSC Jarun is alkaline and moderately supplied with nitrogen, very poorly supplied with phosphorus and well supplied with potassium. The soil in the Park Bundek is neutral and moderately supplied with nitrogen, very poorly supplied with phosphorus and slightly supplied with potassium. Consequently, we suggest spring fertilization on both locations with 100 g m–2 NPK 5-20-30 or 7-14-21 with the addition of 20 g m–2 superphosphate because of low P status both in soil and grass leaves and two topdressings during the growing season with 10 g m–2 KAN because of mowing.
