Fertilizer exports for the United States have begun to stabilize after their numbers fell just a few years back. According to The Fertilizer Institute, nitrogen (N), phosphorous (P) and potassium (K) are the three primary components of fertilizer and the United States is the second largest producer and consumer of fertilizer in the world.

The top five fertilizer-consuming states are Illinois, Iowa, Ohio, Texas and Indiana, and the fertilizer manufacturing industry is responsible for approximately 33,000 jobs in the United States. The U.S. nitrogen fertilizer industry operates production plants in 27 states, the phosphate fertilizer industry operates production plants in 12 states and potash is mined in Michigan, New Mexico and Utah.
