The high yields achieved in crop production in the United States require that large amounts of nutrients be applied to the soil to replace those withdrawn during the production cycle. While animal manure and other organic materials contribute to nutrient replacement, commercial fertilizers remain the major source of applied plant nutrients. ERS provides information on U.S. fertilizer trade, commercial fertilizer application rates, and the adoption of nutrient management practices for selected crops.
