Description
Some ecological aspects were studied in semi-natural and temporary grasslands at different levels of fertilizer application. The research was carried out in the upland region of central Slovakia at the altitude of 460 m in Banská Bystrica. At zero fertilizer application, soil CO2 production and Cox content were higher in the temporary grassland. Atmospheric N fixation was also higher in the temporary grassland. However, root accumulation, microbial biomass content and R : S ratio were lower in the temporary grassland. By comparison with the semi-natural grassland, leaf area index (LAI), net assimilation rate (NAR) and crop growth rate (CGR) were higher in the temporary sward. Mean number of grasshoppers was 325 pc/10 m2 in the semi-natural grassland. The number rose with higher N rates applied. Fixation of N2, amount of microbial biomass and R : S ratio decreased at fertilizer application in both the grassland types. On the other hand, root accumulation increased.
