Control fertiliser usage; this action will show a high decrease in the effect of harmful growth of algae
How will it work?
The fertilisers are chemical or biological mixtures that provide the essential inorganic and organic nutrients that a soil ordinarily lacks yet that plants need for healthy growth and crop production.
Increased fertiliser use has the potential to contaminate both land and water. Due to the addition of fertiliser minerals to the nearby water body as a result of surface runoff, plants and algae flourish excessively due to the availability of nutrients. Eutrophication is the term for this phenomenon.
As a result, fertilisers should only be used in limited quantities to prevent eutrophication.
