Harmful algal blooms can occur when noxious aquatic organisms grow in the presence of elevated urea concentrations. Urea-based fertilizers are ubiquitous, but decompose rapidly in soils. Thus, high urea concentrations found in discharge from agricultural watersheds following storm events during midto late summer, weeks after fertilization, are unexplained by the transport of untransformed fertilizer from fields to waterways.
