Nitrogen standing stock in Phragmites australis growing in constructed wetlands-Do we evaluate it correctly?
Original language description
It is quite obvious that nutrient standing stocks in live biomass depend on both nutrient concentrations in the plant tissue as well as on the amount of live plant biomass. While determination of plant biomass is usually easy through harvesting of defined area of vegetation, determination of nitrogen concentration of the biomass is complicated by the fact that the concentration varies widely in various plant tissues and also in relation to position on the shoot. During 2013, three constructed wetlands and five natural stands were surveyed in order to evaluate biomass of plant tissues (leaves, stems and flowers) and nitrogen concentrations in these tissues in relation to their position on the shoot. Our study clearly indicated that most biomass weight is formed by lower parts of the stems (33%) followed by middle stem parts (19%) and leaves from the upper part of the shoot (18.8%). The nitrogen standing stock exhibited the opposite pattern with the highest values found in the upper leav
