Over 2004Over -2006, effects of mineral fertilisers (60 N + 30 P + 60 K kg/ha or 120 N + 30 P + 60 K kg/ha) and farmyard manure (12 or 24 t/ha) application on biological and chemical properties of soil were studied in seminatural grassland. The research trial was established at Radvaň site, central Slovakia (altitude 480 m, loamy to sandy-loamy Cambisol). These parameters were investigated during the growing seasons: CO 2 production, intensity of total N mineralisation (TMN), the rate of nitrification (NIT), total C content in microbial biomass (MB-C), C ox , N t , P, K, Mg and the humic acids to fulvic acids ratio (HA:FA). At the application of mineral fertilisers, the highest N rate significantly increased TMN and NIT, mainly in 2004 and 2005. The manure application showed the strongest effects on the biological parameters. The manure rate of 12 t/ha significantly increased the soil respiration in 2005 and 2006 as well as TMN and NIT throughout the research. The manure application increased also the soil pH, MB-C, N t , Mg, P and C ox .

Meadow grassland communities were monitored in situ in the region around the town of Banská Bystrica (Central Slovakia) over the 2008 growing season. The botanical compositions were determined at the sites listed in NATURA 2000 (Donovaly, Tajov, and Priechod). The respective site coordinates were determined using a Global Position System, and then put on the digital map of the Google server. A range of rare, endangered, and protected plant species were found at the monitored sites (e.g. Gymnadenia densiflora, Lilium bulbiferum, Lilium matragon, and Stipa joannis).
