Non-toxic species of desiccated blue-green algae, or cyanobacteria, may offer potential for use as a fertilizer on irrigated crops. Here, the non-toxic cyanobacteria species Aphanizomenon flos-aquae (AFA), collected from Upper Klamath Lake, Oregon, was evaluated for use as a biofertilizer in a controlled experiment on Swiss chard “Bright Lights” (Beta...
Cyanobacterial harmful algae blooms (cyanoHABs) are a growing concern worldwide due to damage of ecosystems and threats to human health. Previous research indicates that plant humics from aquatic and wetland vascular plants are effective inhibitors of cyanobacterial metabolism and growth and may be useful as control agents for mitigating cyanoHABs....
Upper Klamath Lake in south central Oregon annually experiences intense
blooms of cyanobacteria, primarily Aphanizomenon flos-aquae. Domination of the
lake phytoplankton community by this single species regularly results in drastic
changes to water quality. Photosynthetic activity of such extensive populations can
result in pH over 10. Blooms typically expire in...
