Case studies on cultural eutrophication on watersheds around lakes that contribute to toxic blue-green algal blooms

Abstract

Over the years, farmers have sought fertilizers containing increasing amounts of phosphorus and nitrogen to enhance crop yields. Excess nutrients, particularly phosphorus and nitrogen, are known to stimulate excess growth of blue-green algae (cyanobacteria). Cyanobacteria blooms are also named cyanobacteria harmful algal blooms (CHABS). These harmful blooms are detrimental to people, profits, and aquatic ecosystems and are increasing in abundance. This chapter summarizes the process of cultural eutrophication, the connection to farming, and sustainable means of remediation.
