What can too much fertiliser cause?
Fertilisers increase crop yields but cause the problem of eutrophication when they're ... However, if too much fertiliser is used it can pollute water supplies.
Pollution due to excessive fertilisers used by farmers leading to Eutrophication?
Over-application of chemical fertilisers or application of chemical fertilisers at a time when the ground is waterlogged or the crop is not able to use the chemicals, can lead to surface runoff or leaching into groundwater Storage and application of some fertilisers in some weather or soil conditions can cause emissions of the greenhouse gas nitrous oxide (N2O) primarily associated with the use of artificial fertilisers, because of the massive quantities applied and the destructive nature of chemical fertilisers on soil nutrient holding structures The high solubility of chemical fertilisers also exacerbates their tendency to degrade ecosystems
Why do algal bloom occurs?
An increase in nutrients can cause algae growth and reproduction to increase dramatically into a bloom.
What dangers are there to humans from fertilisers?
it can cause rashes to the bodu
What are the cause and effects of Eutrophication?
Massive production of Algae
How can a new fertilizer help the environment?
Fertilisers can cause eutrophication, this is where fertilisers run off hills or steep surfaces when it rains. The fertilisers then run into rivers, where eutrophication takes place, it starts by increasing the amount of phytoplankton in the water, this then blocks out the sunlight, which leads to plants being unable to photosynthesise, which in turn means that the fish and other creatures don't have anything to eat, which means they die and then in turn so do other animals that depend on them such as birds.
Which fuel source has the greatest potential to cause eutrophication?
either diesel or gas
What eutrophication and what are the steps that cause it to happen?
Eutrophication is where a body of water somehow acquires an excessive amount of nutrients and as a result, has a boom in biotic life. Eutrophication usually occurs because the Nitrogen-rich fertilizers are brought into the lake due to rain.
Why is eutrophication bad?
Natural eutrophication isn't as much of a problem as artificial eutrophication. Artificial eutrophication is caused by humans (fertilizer from farms, lawns, gardens, etc. pesticides, herbicides, road chemicals, etc) these chemicals cause eutrophication to happen much faster than it should. If eutrophication happens faster, algal blooms (large floating mats of algae) form. When algal blooms decay, the bacteria that decays it depletes the oxygen in the lake or pond and the fish die of suffocation.
What is overused landfills?
They are a cheap solution to get rid of wastes. They can cause leaks in toxins and pollution.
What is the usual cause of cultural eutrophication in surface waters of both developed and developing countries?
lucia the evil one
How can eutrophication destroy the habitat?
Eutrophication can cause loss of oxygen in the water with severe reductions in fish and other animal populations. Other species may experience an increase in population that negatively affects other species in the local ecosystem.
