NITROGEN LEVELS ON A DECLINE IN ‘NITROGEN-RICH WORLD’

In a recent study, an imbalance in nitrogen availability has been reported across the globe, with some places having an excess and others a shortage of the element. Nitrogen availability has been shrinking in grasslands in central North America for a hundred years. Many forests in North America and Europe have also suffered from nutritional declines for several decades or longer due to the same reason.
