Abstract Phosphorus is an essential macronutrient for all living plants and plant production. Simultaneously, atmospheric nitrogen deposition also affects plant productivity at a global scale. However, few studies have investigated how plants respond to P addition while simultaneously considering N deposition. We investigated plant biomass, nutrient status and stoichiometric ratios on Potentilla tanacetifolia in response to P fertilization under contrasting N addition rates in a typical meadow steppe in Inner Mongolia, China. Aboveground biomass of P. tanacetifolia increased under increasing levels of P fertilization under conditions of N addition. However, there was no significant change in biomass when… More >
