Effect of fertilizer application on Urtica dioica and its element concentrations in a cut grassland
Original language description
Little is known about the effects of nutrient availability in cut grasslands on growth characteristics of Urtica dioica and its aboveground chemical composition (N, P, K, Ca, Mg, Cu, Fe, Mn and Zn). The effects of N, P and K application on the growth ofU. dioica were studied over five years in a Dactylis glomerata grassland cut twice per year under unfertilized control, P, N, NP and NPK treatments (300, 80 and 200 kg of N, P and K ha-1 per year). Nitrogen application in the form of NH4NO3 over five years decreased the soil pH, while P and K application increased P and K availability in the soil. Over five years, cover of U. dioica increased from 1% initially to 7, 9, 58, 83 and 99% in the control, P, N, NP and NPK treatments, respectively. Concentrations of N, P and Ca in the aboveground biomass of U. dioica were very high in comparison to other species and concentrations of Cu, Fe, Mn and Zn were comparable with other grassland species. N and P limitation of U. dioica growth was expe
