"Mass application of nutrients causes pollution in some areas while under-use hampers food production in others."
"The world is facing a fertiliser crisis, with far too little in some places, and far too much in others, a new report from the United Nations says today.
The mass application of nitrogen, phosphorus and other nutrients needed for plant growth has had huge benefits for world food and energy production, but it has also caused a web of water and air pollution that is damaging human health, causing toxic algal blooms, killing fish, threatening sensitive ecosystems and contributing to climate change, says the report, “Our Nutrient World”.
However, in some parts of the world, insufficient access to fertilisers remains the problem, and still hampers food production and contributes to land degradation – even while supplies of some nutrients such as phosphorus are more and more seen to be limited."
