TIZKAR, B; SEIDAVI, A; SUDAGAR, M  and  PONCE-PALAFOX, JT. Temporal variation of phytoplankton populations in response to granular and liquid fertilizers. Phyton (B. Aires) [online]. 2014, vol.83, n.1, pp.109-116. ISSN 1851-5657.

The aim of this study was to determine the effect of a granular or liquid fertilizer on the temporal variation of phytoplankton. Enrichment of the pond water with nitrogen and phosphorus resulted in an increased gross photosynthesis and biomass of the dominant algal species. Nutrient concentrations and dilution rates can determine the temporal variation in phytoplankton abundance and primary production. The variation may be largely maintained by nutrient regeneration or turnover from different forms.
