A Brief History of Our Deadly Addiction to Nitrogen Fertilizer
As investigators and rescuers move through a destroyed fertilizer
factory in West, Texas, it makes me think about just what nitrogen
fertilizer is, and why we use so much of it.
Nitrogen is one of the nutrient elements plants need to grow. Every apple or ear of corn plucked represents nutrients pulled from soil, and for land to remain productive, those nutrients must be replenished. Nitrogen is extremely plentiful—it makes up nearly 80 percent of the air we breathe. But atmospheric nitrogen (N2) is joined together in an extremely tight bond that makes it unusable by plants.
