Pesticide use on 21 selected crops more than tripled from 1960 to 1981, but has since declined from 632 million pounds to 516 million pounds in 2008, partly due to more efficient active ingredients, Integrated Pest Management, and GE seeds.

Farmers planted about 170 million acres of GE crops in 2013.
ERR-162, February 20, 2014
Farmer adoption of GE crops is associated with time savings, lower insecticide use, and more conservation tillage. Consumer acceptance of GE ingredients varies across countries, product characteristics, and level of information.

Wheat, the third-largest U.S. crop in volume and value, has distinct varieties grown in different regions or seasons. ERS looks at the variation in growers’ production costs, yields, practices, and profitability across the United States.
EIB-112, May 13, 2013
Farmers have adapted to rising energy prices and evolving policies by adjusting their use of energy-based agricultural inputs, altering energy-intensive production practices, and growing more energy-feedstock crops.

The largest agricultural input firms are responsible for a large and growing share of global agricultural research and development (R&D). See the December issue of ERS’s Amber Waves magazine.
EB-20, November 14, 2012
Nitrogen is a critical input in agriculture, and corn is the largest user of nitrogen. An examination of nitrogen management on corn cropland indicates that corn producers appear to be applying less excess nitrogen.
EB-19, September 21, 2012
Eight-page brief examines the funding and performance of agricultural R&D to assess the evolving--and complementary--roles of the public and private sectors in the U.S. agricultural research system.

The 2012 edition provides resource-and environment-related information including farmland area, productivity, irrigation, pesticide use, adoption of genetically engineered crops, fertilizer use, conservation practices, and land retirement.
ERR-130, December 30, 2011
ERS quantifies investment trends by for-profit companies in food manufacturing, biofuels, and agricultural input R&D and explores how the trends are affected by changes in industry structure.
EIB-90, December 30, 2011
Meeting growing global demand for food, fiber, and biofuel requires robust investment in agricultural research and development (R&D) from both public and private sectors. This report highlights the major findings of a study examining global R&D spending by private industry in seven agricultural inpu...

Nitrogen is an important agricultural input that is critical for crop production. However, the introduction of large amounts of nitrogen into the environment has a number of undesirable impacts on water, terrestrial, and atmospheric resources. This report explores the use of nitrogen in U.S. agricul...
Amber Waves, September 01, 2011
Agriculture is the single largest source of nitrogen compounds that can help or harm ecosystems. A range of policy instruments could be used to address different facets of nitrogen management and specific environmental problems.
ERR-123, August 18, 2011
ERS looks at direct and indirect impacts of higher energy prices on the agricultural and rural sectors, with scenarios developed for specific energy price changes.
AP-037, June 25, 2009
The Food, Conservation, and Energy Act of 2008 directed the U.S. Department of Agriculture to evaluate the role of animal manure as a source of fertilizer, and its other uses. About 5 percent of all U.S. cropland is currently fertilized with livestock manure, and corn accounts for over half of the a...

Strong domestic and global demand, coupled with tight supplies and low inventories, contributed to record fertilizer prices in early 2008. Softening global fertilizer demand, disruptions in U.S. farmer application of fertilizers, an increase in fertilizer imports, and tighter credit for purchasing i...
AR-33, February 13, 2009
U.S. prices of fertilizer nutrients began to rise steadily in 2002 and increased sharply to historic highs in 2008 due to the combined effects of a number of domestic and global long- and shortrun supply and demand factors. From 2007 to 2008, spring nitrogen prices increased by a third, phosphate pr...
WRS-0702, August 06, 2007
The volatile and upward trend in U.S. natural gas prices from 2000-06 has led to a 17-percent decline in the Nation’s annual aggregate supply of ammonia. During the period, U.S. ammonia production declined 44 percent, while U.S. ammonia imports increased 115 percent. Also, the share of U.S.-produced...
