Fertilisers, though currently essential to Australia's agriculture industry, are being over-used in order to extract as much profit from the land as possible. Excessive consumption results in devastating consequences to our surrounding environments as these often harmful chemicals are carried by runoff into local waterways.
When fertilisers are flushed into a waterway they alter its balance of nutrients. This creates room in an ecosystem for the bloom of a singular species. The species uses the excess of nutrients to reproduce at a rapid rate, disturbing the pre-existing eco-system. These blooms smother organisms through a variety of mechanisms such as reducing light availability - constraining the ability of photosynthesis to occur. This destabilises the entire ecosystem by creating knock on effects up the food chain.
It is clear that the use of fertilisers have negative environmental impacts, so how do we reduce or eliminate their impact?
