The influence of seabird manuring on the phosphorus status of Marion Island (Subantarctic) soils
Tóm tắt
Manuring by penguins, wandering albatrosses and burrowing petrel and prion species substantially enhances P concentrations in Marion Island soils and plants. Non-manured soils contain low levels of plant-available P on a soil volume basis but the evidence suggests that the island soils are primarily deficient in N rather than P.
