摘要:Fertilizer composition and use has important implications for coastal resiliency. The concept of coastal resiliency has received increased attention in recent years in the context of climate change.5Coastal resiliency refers to a given coastal system's adaptive capacity to external disturbances. That which enhances the ability of coastal ecosystems to prevent or cope with the impacts of external disturbances is understood as having a positive impact on coastal resiliency. Resiliency can be strengthened mainly by decreasing the probability of occurrence of coastal hazards or avoiding or reducing their potential effects.6Harmful algal blooms (HABs) are a specific coastal hazard that have received increased attention over the past decade. Algal blooms involve high concentrations of photosynthetic algae, cyanobacteria and non photosynthetic protists.7HABs are a subset of algal blooms that cause harm by releasing toxins, altering habitat, displacing indigenous species, or depleting oxygen in the water. The U.S national plan for algal toxins notes that recent years have been characterized by a dramatic increase in the number of HABs and the economic losses resulting from them.8This increase can be linked, in part, to increased nutrient loading.9Nitrogen loading resulting from fertilizer use is of particular concern
