Agricultural Production and Prices
Markets for major agricultural commodities are typically analyzed by looking at supply-and-use conditions and implications for prices. From an economic perspective, these factors determine the market equilibrium. In the U.S. agricultural sector, many interactions and relationships exist between and among different commodities. For example, corn production and prices affect feed costs in the livestock sector.
The United States produces and sells a wide variety of agricultural products across the Nation. In terms of sales value, California leads the country as the largest producer of agricultural products (crops and livestock), accounting for almost 11 percent of the national total, based on the 2012 Census of Agriculture. Iowa, Texas, Nebraska, and Minnesota round out the top five agricultural-producing States, with those five representing more than a third of U.S. agricultural-output value.
California, Iowa, Illinois, Minnesota, and Nebraska are the five States with the highest value of crop sales. With its large horticultural sector, California's overall crop value of more than $30 billion in 2012 is about 75 percent higher than that of Iowa, the second-ranked State. In contrast to California, crop values in the next four leading States derive from grains and oilseeds, particularly corn and soybeans. For other crops, Washington State typically leads the country in apple production, while Florida is the largest producer of oranges.
Livestock production and sales occur in all 50 States. Texas, Iowa, California, Nebraska, and Kansas lead the country in sales value of livestock and their products. The cattle sector is the dominant source of value in Texas, Kansas, and Nebraska. Milk from cows accounts for about 57 percent of livestock-sale value in California. Both the hog and cattle sectors are large sources of sales value in Iowa. North Carolina is the leading producing State of poultry and eggs, followed by Georgia.
Since 1990, combined acreage planted to corn, wheat, soybeans, and upland cotton in the United States has ranged from 219 million to 242 million acres. Starting in the 1990s, policy changes increased planting flexibility provided to farmers. These changes have allowed farmers to respond to market signals in their cropping choices. Over the past 10 years (2011–2020), the combined annual planting acreage for these crops has maintained a higher average (236 million acres) than the prior decade (228 million acres). Since 1990, the three highest combined annual planting totals for these crops occurred in 2012, 2014, and 2018. Acreage dropped in 2019, mostly as a result of a large decrease in the planting of soybeans.
U.S. fruit and tree nut value of production has increased steadily over the past decade, while the value of vegetable production has been more stable. Grapes, apples, strawberries, and oranges top the list of fruits; tomatoes and potatoes are the leading vegetables. Tree-nut value rose dramatically to record levels of around $10 billion in recent years, with crop value for most major tree nut crops led by almonds, walnuts, and pistachios achieving historical highs.
With only a few exceptions, production of broilers (the most efficient converter of feed to meat) has outpaced growth in beef and pork production since 1990, and poultry meat has been the major meat produced and consumed in the United States since the mid-1990s. Total domestic per capita beef, pork, and poultry disappearance (a proxy for use) is beginning to increase again after several years of decline that reflected higher feed costs, higher retail prices, and effects of the 2007-09 economic recession. Exports of meats and products also continue to be an important source of demand.
The number of milk cows in the United States generally fell in the 1980s and 1990s but has generally risen since the early 2000s. Milk output has risen 70 percent since 1980 and in 2019 exceeded 218 billion pounds per year. Genetic developments and technological improvements underlie a pronounced upward trend in milk output per cow. Consolidation in the dairy sector also has facilitated efficiency gains in milk production.
Corn is the major agricultural input used in the United States to produce ethanol, which has accounted for over 40 percent of U.S. corn use in recent years. Rapid expansion of ethanol production in the past decade reflected a response to high crude oil prices, the Renewable Fuel Standard, and other factors. However, ethanol production has generally plateaued as oil prices have fallen and the gasoline market has hit a 10-percent blend constraint.
The 10-year phase-out of textile and apparel import quotas that existed under the international Multifiber Arrangement was completed at the start of 2005, leading to increased U.S. imports of those products and contributing to reduced U.S. cotton mill use. As a result, U.S. raw cotton exports have become increasingly important. Exports now account for approximately 85 percent of overall use of U.S. cotton, compared with less than 40 percent in the 1990s. The United States is the leading global exporter of cotton. Vietnam and China are the largest destinations for U.S. cotton exports.
Although prices for agricultural commodities frequently vary from year to year, they have generally moved higher since 2000. In these aggregate measures, inflation adjusted prices for crops were up more than 38 percent above their 2005 levels, while those for livestock rose over 29 percent from 2006 to 2018. Prices for both crops and livestock have fallen since 2014, however, as U.S. and global markets responded to higher prices by increasing production.
Increased productivity in crop production underlies a general decrease in inflation-adjusted prices for corn, wheat, and soybeans over the past century. This downward price trend was reversed during the past decade by global growth in population and income, increasing biofuel production, and a depreciation of the U.S. dollar, but is likely to resume from these recent higher levels as population and income growth slow, biofuel production levels off, and as the U.S. dollar strengthens.
Cattle, hog, and broiler prices have not kept pace with inflation over the past 30 years. Inflation-adjusted hog prices have been lower than 1990 prices from 1991 on. The highest inflation-adjusted cattle and broiler prices in the past 30 years were in 2014. (2014 inflation-adjusted hog prices were the highest they have been in the 21st century.) From 2000 to 2014, inflation-adjusted meat prices reflected slower production growth as meat output responded to lower producer profits due in part to rising feed costs. Cattle production costs, production, and prices also were affected by poor forage conditions due to lingering droughts over much of the past decade, particularly in the Southern Plains. As feed prices have softened, however, livestock production has risen since 2015, lowering U.S. livestock prices.
