Document Summary
Consequences of excessive nutrient loading on aquatic ecosystems in extreme cases of eutrophication, massive fish kills can occur in sensitive lakes and rivers. The kills result from anoxic conditions that are brought on by the decay of the masses of algae stimulated by elevated inputs of phosphorus (or sometimes of nitrogen). How to mitigate environmental risks?-->goals of nutrient management develop nutrient budgets a useful step in planning nutrient management is to conceptualize the nutrient flows for the particular system under consideration. Such a flowchart should attempt to account for all the major inputs and outputs of nutrients. Consequence of getting it wrong at continental scales the gulf of mexico dead zone the. Gulf of mexico dead zone is an area of hypoxic (less than 2 ppm dissolved oxygen) waters. Its area varies in size, but can cover up to 6,000-7,000 square miles.
