Pesticide use has held steady while some types fluctuate slightly

Friday, September 28, 2012

Total pesticide use on corn, cotton, fall potatoes, soybeans, and wheat was stable during 1982-2010, increasing in some years and declining in others, with an average annual increase of 0.2 percent. Herbicide and insecticide quantities applied declined 0.2 percent and 3.9 percent per year, while fungicide and other-chemical quantities increased 3.3 and 6.0 percent. Changes in the use of pesticides during this period are due to several factors, including the widespread adoption of genetically engineered crops, the expiration of the glyphosate patent in 2000, the availability of new compounds with lower application rates, boll-weevil eradication, and changes in pesticide prices, which increased slowly compared to the prices of other inputs such as fertilizer. This chart can be found in the ERS report, Agricultural Resources and Environmental Indicators, 2012 Edition, EIB-98, August 2012.

Fertilizer prices trend upward, often outpacing recent growth in crop prices

Tuesday, May 15, 2012

Fertilizer prices paid by farmers outpaced the increase in crop prices received by farmers from 2004 to 2008, driven largely by high energy prices and input material costs. In response to record fertilizer prices in 2008, farmers reduced fertilizer consumption, which contributed to a large decline in fertilizer prices in 2010. Since then, fertilizer prices have started to climb once again, driven mainly by strong domestic demand for plant nutrients resulting from high crop prices despite a steady decline in nitrogen fertilizer input (natural gas) costs. This chart is based on the data in table 8 of the ERS data product, Fertilizer Use and Price, updated May 4, 2012.
