DOIAbstract
The use of nitrogen and phosphorus sediment fertilization for seagrass restoration is explored. Special attention was given to the effects of nitrogen sediment fertilization. The sediment fertilization treatment combined different levels of nitrogen (0, 30, 500 mg N g DW-1) with sufficient phosphorus to avoid P-limitation (fertilizer N:P ratio<0.25). Using indoor mesocosms, we studied the effects of sediment fertilization, and its interactions with light availability (55, 200 mol m-2 s-1) and sediment redox conditions (300, -100 mV), on Zostera marina L. We assessed (1) treatment effects on growth and plant biomass distribution, (2) the capacity of Z. marina roots to meet the plant nutrient demand, (3) plant tolerance to high nutrient porew...
