EUTROPHICATION

BY KENGO, MATT and DERGLAS

Causes

• Natural run-off nutrients from the soil and the weathering of rocks

• Run-off of inorganic fertilizers

• Run-off from farm manure and erosion

• Discharge of partially treated or untreated sewage and other harmful chemicals such as detergents

Consequences

• Increased vegetation may impede water flow and the movement of boats

• Decrease in the amenity of the water• Disappearance of commercially important species• The water may become unsuitable for drinking

water even after treatment

Ways to Control EutrophicationEutrophication can be avoided by using minimal

required amounts of chemical fertilizers or better still do away with them and use natural ones instead.

Don’t have fields too close to bodies of water and clear manure and loose soils to stop erosions.

When using fertilizers during monsoons as due to run-offs they get transmitted to the water bodies. Then, they can cause blockage, death of marine life, and breakage of food chains.

Debate in Fertilizers There is a huge debate in the world about Fertilizers used on golf courses and how it is damaging the ground. Throughout the year there are many chemicals put onto the grass and used to keep it clean and free of diseases. Phosphorus is a large chemical used and in Australia there is a case where the ground has been damaged and slowing down a large amount of growth of plants which leads to a shorter life and as the climate changed they cant survive the change and die. On the whole they have drastically changed he future of natural plant growing in the area.
