Fine root biomass and morphology in a temperate forest are influenced more by canopy water addition than by canopy nitrogen addition

Introduction Increasing atmospheric N deposition and changes in precipitation patterns could profoundly impact forest community structure ecosystem functions. However, most water (W) addition experiments have focused on direct application to leaf litter or soil, neglecting canopy processes such as evaporation absorption. Methods In this study, we aimed assess the effects of increased fine root biomass morphology plants a temperate deciduous forest. To achieve this, applied W above quantified seasonal dynamics (January, July, October) morphology. Results Our results revealed that only significantly roots January compared other seasons ( p < 0.05). We observed no significant interaction effect biomass. found different growth had 0.001). The combined affected tip density = 0.002). Although was positively correlated with available soil 0.05), detected association Discussion findings study indicated morphology, are greater extent by provision than application. These provide new perspective more precise understanding actual plant ecosystems.
