Artificial fertilizers have become a vital tool in food production around the globe . They are responsible for many of the gains of the agricultural revolution of the 20th century, which has enabled the world to feed many of its growing population. Artificial fertilizers provide many benefits to crops including nitrogen and phosphorus, key limiting nutrients, to crop plants, removing the normal barriers that would otherwise limit the rate of growth. As a result, fertilized crops grow much more rapdily, and farms that use fertilizer produce much larger crop yields.
However, careless use and overuse of artificial fertilizers have been demonstrated to have significant negative impacts on aquatic ecosystems, both freshwater and marine. Fertilizers that are applied at inappropriate times or in too-large quantities allow nitrogen and phosphorus compounds to escape use by crop plants and enter drainage systems. Inappropriate use of fertilizers in residential settings can also contribute to nutrient loads, which find their way to lakes and coastal marine ecosystems. As water warms and nutrients are plentiful, microscopic algae bloom, often changing the color of the water because of the high cell density.
Most algal blooms are not directly harmful to humans or wildlife; however, they can cause harm indirectly. As the algal population expands and then dies, it provides a large increase in organic matter to the bacteria that live in deep water. With this large supply of nutrients, the population of nonphotosynthetic microorganisms explodes, consuming available oxygen and creating “dead zones” where animal life has virtually disappeared.
Depletion of oxygen in the water is not the only damaging consequence of some algal blooms. The algae that produce red tides in the Gulf of Mexico, Karenia brevis, secrete potent toxins that can kill fish and other organisms and also accumulate in shellfish. Consumption of contaminated shellfish can cause severe neurological and gastrointestinal symptoms in humans. Shellfish beds must be regularly monitored for the presence of the toxins, and harvests are often shut down when it is present, incurring economic costs to the fishery. Cyanobacteria, which can form blooms in marine and freshwater ecosystems, produce toxins called microcystins, which can cause allergic reactions and liver damage when ingested in drinking water or during swimming. Recurring cyanobacterial algal blooms in Lake Erie have compelled local towns to issue drinking water bans for weeks at a time because of highly elevated toxin levels.
This is just a small sampling of the negative consequences of algal blooms, red tides, and dead zones. Yet the benefits of crop fertilizer—the main cause of such blooms—are difficult to dispute. There is no easy solution to this dilemma, as a ban on fertilizers is not politically or economically feasible. In lieu of this, we must advocate for responsible use and regulation in agricultural and residential contexts, as well as the restoration of wetlands, which can absorb excess fertilizers before they reach lakes and oceans.
Algae Bloom Eliminator (ABE-20) is a unique mineral composition formulated for the control of algae blooms. ABE-20 is a non toxic formulation designed to treat water bodies where human activities are present. ABE-20 is effective in all temperatures and can remove any type of algae. In laboratory testing, we were able to neutralize algae within 24 hours. Algae can be both harmful and toxic to humans. Nearly one fourth Phytoplankton blooms are toxic and exposure in those people with weak immune systems can sometimes be fatal.
All over the world and including in Canada, algae blooms are present in select water bodies. Not only are they harmful but they reduce the visual appeal of a lake and can negatively impact the ecosystem. Algae increases the biological demand on a water body and deprives aquatic species from taking in enough oxygen.
ABE-20 is a broad-spectrum non-biocide algaecide that combats/inhibits algae bloom in lakes and rivers. It does not contain any chemicals or copper which can harm the environment. It eliminates blue green, brown, hair algae and blanket weed.
