Algae
Management in Lakes and Ponds

Based on the
stoichiometric composition of algae, typically, either nitrogen (N) or
phosphorous (P) is the element present in the algal environment that, when
supplied at a rate less than needed, can limit the growth of algae; this is the
limiting element. This is important in managing eutrophication-related
water-quality impairment.
