Fertilizer use has fluctuated over time and varied by primary nutrient

Fertilizers provide nutrients (such as nitrogen, potash, and phosphate) essential in the production of crops. The total consumption of fertilizers grew rapidly throughout the 1960s and 1970s, as U.S. farmers devoted more acreage to crop varieties and hybrids (such as corn and wheat hybrids) that respond well to more intensive use of commercial fertilizer, especially nitrogen. In 1960, farmers used about 7.5 million short tons of fertilizer—and use peaked at nearly 23.7 million short tons in 1981. After 1981, total fertilizer use fluctuated from year to year but displayed no trend, as modest growth in nitrogen use was offset by modest declines in potash and phosphate. Annual fluctuations in fertilizer use since 1981 reflected several factors, including changes in fertilizer and crop prices and changes in the mix of crops (e.g., corn uses more fertilizer than soybeans or wheat). Higher fertilizer prices limited use to some extent, while higher crop prices encouraged greater fertilizer use. Finally, macroeconomic events can affect use: for example, fertilizer use dropped in 2009, concurrent with the Great Recession.
